Калилец THE IMPORTANCE OF ORATORICAL SKILL OF AN ADVOCATE IN THE TRIAL To begin with, the oratorical skill was born in Ancient Greece, where with the gradual development of statehood, the activity of the masses in the domestic life of Greek policies increased. The fate of many politicians depended on their ability to speak publicly. So, this skill was taught and widely appreciated [1]. As for the present time, the oratorical skill, as an integral part of the professional competence of a lawyer, is a complex of the speaker‟s skills and knowledge in preparing and pronouncing of a public speech. First and foremost, this is the ability to select the appropriate material; this is the skill of constructing speech and public speaking with the task of having a certain impact on listeners; this is the ability to prove and disprove, the ability to persuade and over-persuade; it is a speech skill. The shortcoming of today‟s law graduate lies not in a deficient knowledge of law but that he has little, if any, training in dealing with facts or people – the stuff of which cases are really made. It is a rare graduate, for example, who knows how to ask questions – simple, single questions, one at a time, in order to develop facts in evidence either in interviewing a witness or examining him in a courtroom. And a lawyer who cannot do that cannot perform properly – in or out of court. Inasmuch as the lawyer defends the interests of citizens in court, he will certainly participate in criminal proceedings, an integral part of which is judicial debate, in which the public prosecutor and the defender state their conclusions, namely, pronounce the court speeches. Trial advocacy is the art of persuasion. More completely, trial advocacy is the composition of fact extraction, legal reasoning, strategic judgment, and persuasive speech, structured by the rules of professional responsibility, evidence, procedure and substantive law. Cases are not won or lost merely by applying a particular principle of law or legal rule. Rather, these principles and rules become effective only in the hands of an advocate who supports them with a strong factual foundation and propounds them with persuasive argument. The purpose of judicial speech, first of all, is to: 1) to establish the issue; 2) to promote certain persuasion of judges (jurors). In the presence of the jury, the oratorical skill is even more powerful, because in this situation, the human factor is manifested to a greater extend. Also, judicial speeches increase the level of legal literacy of citizens and bring up respectful attitude to the law. There is no doubt that oratory plays an important role in the professional activity of the lawyer. This is one of the most responsible, complex and creative moments of his participation in criminal proceedings. It should be noted that some other form of procedural activity does not impose so many demands on the lawyer and does not need such thorough and in-depth preparation as the pronouncement of court decisions in judicial debate [2]. When one thinks of “trial advocacy,” perhaps the first image is that of great courtroom orator, the “king of the advocacy”, Vladimir Danilovich Spasovich. He was not merely a technician trained in the mechanics of courtroom skills and etiquette, but a 4 lawyer who was able to extract the pertinent facts from a seeming maze of information, integrate those facts with legal principles, and present a reasoned argument. Though, according to Vladimir Ivanovich Taneyev (Russian lawyer), Spasovich‟s lectures at the School of Jurisprudence, shocked the listeners with “incredible tongue-tie”: “He could not properly, coherently say two words. With incredible efforts he seemed to squeeze every word out of himself, helping himself with his hands, feet, head, and the whole body. He irritated the entire nervous system...” [3]. But eventually, thanks to constant hard work, a terrible effort, he became the most famous Russian skillful advocate. “Every thought was a picture, every word was a figure.” The speeches of this great man are an example of the result of multilateral and long-term development not only as a lawyer, but also as a person. It is also worth noting an important feature of Spasovich‟s oratorical manner: it is encyclopedic, obviously not only having legal knowledge with a deep understanding of any secrets of criminalistics, not only wise digressions into history, philosophy, literature, but also persuasive interpretation of ethical, logic, morality issues. In each case, he used his skills of persuasion, which were based on the following ten principles: comprehensiveness; theme; consistency; plausibility; legal Structure; accountability; congeniality; simplicity; community; flexibility. Spasovich always proceeded from the fact that judicial research “must consist in the investigation of truth in exactly the same ways as any study of truth. Therefore, the “nature of judicial speeches,” according to Spasovich, “depends on what views the defender is guided by – whether he sets himself the task of only winning a case, defeating an opponent, or investigating the truth” [3]. Summarizing all of the above, it is worth repealing that legal advocacy is an art that transcends the courtroom walls. It is difficult to conceive of a legal practitioner who does not, in some way and at some time, utilize the skills of advocacy – fact analysis, legal integration, and persuasive presentation. Oratory is an advantage through which you can achieve success. REFERENCES 1. Жидков, О. А. История государства и права зарубежных стран : учеб. пособие для студентов вузов : в 2 ч. / О. А.

Акопджанова Республика Беларусь, Минск, БГПУ имени М. Танка Научный руководитель – В.М. Шелег THE THEME OF HOMESICKNESS AND NOSTALGIA IN THE SHORT STORY OF WILLIAM SAROYAN “THE ARMENIAN AND THE ARMENIAN” William Saroyan is a well-known American writer of Armenian origin, the writer who made his initial impact during the Depression with a deluge of brash, original and irreverent stories celebrating the joy of living in spite of poverty, hunger and insecurity. Saroyan was concerned with the basic goodness of all people, especially the obscure and naive, and the value of life. His mastery of the vernacular makes his characters vibrantly alive. Most of his stories are based on his impressions of childhood and family priorities [1]. Dark, thin and hawk-like when he was young, peasant-stocky and heavily moustached in later years, Mr. Saroyan dominated all groups, everywhere, with his huge bass voice and his booming laugh. He explained that he came from an ancient tradition of Armenian singers and storytellers – “If I talk too much, it‟s a cultural problem.”[2]. Saroyan‟s famous short story “The Armenian and the Armenian” was written in August 1935 in New York and was first published in 1936. In the story, author tells about his meeting with an Armenian waiter he accidentally meets at a beer parlour in Rostov in 1935. The main hero – an Armenian, meets another one, also an Armenian. But it‟s very interesting how the main hero explains his confidence about the nationality of the waiter: “I don‟t know how I could tell he was an Armenian, but I could. It is not the dark complexion alone, nor the curve of nose, nor the thickness and abundance of hair, nor is it even the way the living eye is set within the head. There are many with the right complexion and the right curve of nose and the same kind of hair and eyes, but these are not Armenian.

  • State of the Art in Lightweight Symmetric Cryptography
    State of the Art in Lightweight Symmetric Cryptography Alex Biryukov1 and Léo Perrin2 1 SnT, CSC, University of Luxembourg, [email protected] 2 SnT, University of Luxembourg, [email protected] Abstract. Lightweight cryptography has been one of the “hot topics” in symmetric cryptography in the recent years. A huge number of lightweight algorithms have been published, standardized and/or used in commercial products. In this paper, we discuss the different implementation constraints that a “lightweight” algorithm is usually designed to satisfy. We also present an extensive survey of all lightweight symmetric primitives we are aware of. It covers designs from the academic community, from government agencies and proprietary algorithms which were reverse-engineered or leaked. Relevant national (nist...) and international (iso/iec...) standards are listed. We then discuss some trends we identified in the design of lightweight algorithms, namely the designers’ preference for arx-based and bitsliced-S-Box-based designs and simple key schedules. Finally, we argue that lightweight cryptography is too large a field and that it should be split into two related but distinct areas: ultra-lightweight and IoT cryptography. The former deals only with the smallest of devices for which a lower security level may be justified by the very harsh design constraints. The latter corresponds to low-power embedded processors for which the Aes and modern hash function are costly but which have to provide a high level security due to their greater connectivity. Keywords: Lightweight cryptography · Ultra-Lightweight · IoT · Internet of Things · SoK · Survey · Standards · Industry 1 Introduction The Internet of Things (IoT) is one of the foremost buzzwords in computer science and information technology at the time of writing.

German Lorenz cipher machine, used in World War II to encrypt very-high-level general staff messages Cryptography (or cryptology; from Greek κρυπτός, kryptos, "hidden, secret"; and γράφ, gráph, "writing", or -λογία, -logia, respectively)[1] is the practice and study of hiding information. Modern cryptography intersects the disciplines of mathematics, computer science, and engineering. Applications of cryptography include ATM cards, computer passwords, and electronic commerce. Cryptology prior to the modern age was almost synonymous with encryption, the conversion of information from a readable state to nonsense. The sender retained the ability to decrypt the information and therefore avoid unwanted persons being able to read it. Since WWI and the advent of the computer, the methods used to carry out cryptology have become increasingly complex and its application more widespread. Alongside the advancement in cryptology-related technology, the practice has raised a number of legal issues, some of which remain unresolved.

  • Cryptography
    Cryptography Cryptography, or cryptology (from Ancient Greek: κρυπτός, romanized: kryptós "hidden, secret"; and γράφειν graphein, "to write", or -λογία -logia, "study", respectively[1]), is the practice and study of techniques for secure communication in the presence of third parties called adversaries.[2] More generally, cryptography is about constructing and analyzing protocols that prevent third parties or the public from reading private messages;[3] various aspects in information security such as data confidentiality, data integrity, authentication, and non-repudiation[4] are central to modern cryptography. Modern cryptography exists at the intersection of the German Lorenz cipher machine, disciplines of mathematics, computer science, electrical engineering, used in World War II to encrypt very- communication science, and physics. Applications of cryptography high-level general staff messages include electronic commerce, chip-based payment cards, digital currencies, computer passwords, and military communications. Cryptography prior to the modern age was effectively synonymous with encryption, converting information from a readable state to unintelligible nonsense. The sender of an encrypted message shares the decoding technique only with intended recipients to preclude access from adversaries. The cryptography literature often uses the names Alice ("A") for the sender, Bob ("B") for the intended recipient, and Eve ("eavesdropper") for the adversary.[5] Since the development of rotor cipher machines in World War I and the advent of computers in World War II, cryptography methods have become increasingly complex and its applications more varied. Modern cryptography is heavily based on mathematical theory and computer science practice; cryptographic algorithms are designed around computational hardness assumptions, making such algorithms hard to break in actual practice by any adversary.

  • How to Evaluate the Security of Real-Life Cryptographic Protocols? the Cases of ISO/IEC 29128 and CRYPTREC
    How to Evaluate the Security of Real-life Cryptographic Protocols? The cases of ISO/IEC 29128 and CRYPTREC Shin’ichiro Matsuo1, Kunihiko Miyazaki2, Akira Otsuka3, and David Basin4 1 NICT 2 Hitachi Ltd. 3 AIST 4 ETH Zurich Abstract. Governments and international standards bodies have estab- lished certification procedures for security-critical technologies, such as cryptographic algorithms. Such standards have not yet been established for cryptographic protocols and hence it is difficult for users of these pro- tocols to know whether they are trustworthy. This is a serious problem as many protocols proposed in the past have failed to achieve their stated security properties. In this paper, we propose a framework for certifying cryptographic protocols. Our framework specifies procedures for both protocol designers and evaluators for certifying protocols with respect to three different assurance levels. This framework is being standard- ized as ISO/IEC 29128 in ISO/IEC JTC1 SC27/WG3, in which three of the authors are project co-editors. As a case study in the application of our proposal, we also present the plan for the open evaluation of entity- authentication protocols within the CRYPTREC project. Keyword: Cryptographic protocols, formal verification, standardization 1 Introduction 1.1 Background Over the past 20 years, many security technologies have been developed using cryptographic protocols. For example, the widely deployed Secure Socket Layer (SSL) protocol, uses a combination of digital signatures, public key cryptography, and symmetric key cryptography. From the viewpoint of users of such security technologies, a major concern is whether they should trust their security. For cryptographic algorithms, such as block ciphers, stream ciphers, hash functions, and public key encryption, open competitions are held by NIST, NESSIE, ECRYPT, and CRYPTREC.

  • Key Management Systems at the Cloud Scale
    cryptography Article Key Management Systems at the Cloud Scale Matthew Campagna 1,† and Shay Gueron 1,2,*,† 1 Amazon Web Services Inc., Seattle, WA 98101, USA 2 Department of Mathematics, University of Haifa, Haifa 3498838, Israel * Correspondence: [email protected] † These authors contributed equally to this work. Received: 14 July 2019; Accepted: 28 August 2019; Published: 5 September 2019 Abstract: This paper describes a cloud-scale encryption system. It discusses the constraints that shaped the design of Amazon Web Services’ Key Management Service, and in particular, the challenges that arise from using a standard mode of operation such as AES-GCM while safely supporting huge amounts of encrypted data that is (simultaneously) generated and consumed by a huge number of users employing different keys. We describe a new derived-key mode that is designed for this multi-user-multi-key scenario typical at the cloud scale. Analyzing the resulting security bounds of this model illustrates its applicability for our setting. This mode is already deployed as the default mode of operation for the AWS key management service. Keywords: AES-GCM; cloud computing; key management 1. Introduction Key management for a public cloud is based on the promise for availability, durability, and absolute security and privacy. This requires the following: (a) adherence to best known cryptographic practices and standards, in a highly available low-latency service; (b) the ability to provide (semantic) security while handling extremely large volumes of requests that are placed by an extremely large number of users that utilize different keys (i.e., a multi-user–multi-key scenario).

    FREE THE JEFFERSON KEY PDF Steve Berry | 512 pages | 12 Apr 2012 | Hodder & Stoughton General Division | 9781444709407 | English | London, United Kingdom The Jefferson Key : Berry's Best | HuffPost When novelist Steve Berry is not at his The Jefferson Key, as was the case with The Emperor's Tombhe is still a good writer. When he is at his best, as he is with The Jefferson Keyhe is a terrific writer. With this latest novel, Berry turns down the volume on his excesses and goes straight for the plot. He manages to make almost five hundred pages seem much too short as The Jefferson Key races from one exciting segment to the next. In some of Berry's previous books he gave us too much background. It was interesting to be sure but it was out of proportion to the plot. This was the case in The Emperor's Tomb. The reader learned so much about Chinese history that we lost our place in the modern day story. By the time that book ended we had had a great history lesson but we were exhausted by the sheer volume of it all. This is not the case with The Jefferson Key. In this one the plot concerns an attempted assassination of the President of the United States, and the rest of the book deals with who did it and why -- and how they can be caught. Berry's great continuing hero is Cotton Malone and he is The Jefferson Key man who comes back to the States just as the attempt is made.
