Course 5 Lesson 2
This material is based on work supported by the National Science Foundation under Grant No. 0802551 Any opinions, findings, and conclusions or recommendations expressed in this material are those of the author (s) and do not necessarily reflect the views of the National Science Foundation C5L3S1 With the advent of the Internet, social networking, and open communication, a vast amount of information is readily available on the Internet for anyone to access. Despite this trend, computer users need to ensure private or personal communications remain confidential and are viewed only by the intended party. Private information such as a social security numbers, school transcripts, medical histories, tax records, banking, and legal documents should be secure when transmitted online or stored locally. One way to keep data confidential is to encrypt it. Militaries,U the governments, industries, and any organization having a desire to maintain privacy have used encryption techniques to secure information. Encryption helps to boost confidence in the security of online commerce and is necessary for secure transactions. In this lesson, you will review encryption and examine several tools used to encrypt data. You will also learn to encrypt and decrypt data. Anyone who desires to administer computer networks and work with private data must have some familiarity with basic encryption protocols and techniques. C5L3S2 You should know what will be expected of you when you complete this lesson. These expectations are presented as objectives. Objectives are short statements of expectations that tell you what you must be able to do, perform, learn, or adjust after reviewing the lesson. -
NSA Vs. Encryption Article Written by Datto Developer Dan Fuhry First Appeared on Mspmentor.Com in November 2013
SuccessArticle: EncryptionStory NSA vs. Encryption Article written by Datto developer Dan Fuhry first appeared on MSPmentor.com in November 2013. If you’ve been watching the news lately, there is no doubt you have heard about the National Security Agency’s (NSA) surveillance scandal. “We will stand in our firm Recent months have seen a revelation of programs commitment to protect you and that capture domestic and international traffic indiscriminately. Encrypted data gets saved for a your customers.” certain number of years, in case they ever decide to decrypt it. If this alarms you, that’s good. You should be alarmed. I was too, on a very personal level, and have actively been working on changing some long-established habits in order to protect the information that is private and personal to me. For MSPs not in the United States you should be even more alarmed. It’s not even your own government that has the encrypted data, and since you don’t have constitutional protection in the U.S., there is nothing legally standing in the NSA’s way to prevent them from using their dark magical cryptographic powers to obtain your confidential business or personal data. This is a frightening proposition indeed, which is why I want to talk about the position Datto has taken regarding the recent revelations. Before we go any further, allow me to briefly describe my role here. I’m a developer with Datto, and I designed the encryption feature for Datto SIRIS. I picked the ciphers, hash algorithm parameters, and random number generator algorithm, had them peer-reviewed, and then wrote the code. -

Implementation and Performance Analysis of PBKDF2, Bcrypt, Scrypt Algorithms
Implementation and Performance Analysis of PBKDF2, Bcrypt, Scrypt Algorithms Levent Ertaul, Manpreet Kaur, Venkata Arun Kumar R Gudise CSU East Bay, Hayward, CA, USA. [email protected], [email protected], [email protected] Abstract- With the increase in mobile wireless or data lookup. Whereas, Cryptographic hash functions are technologies, security breaches are also increasing. It has used for building blocks for HMACs which provides become critical to safeguard our sensitive information message authentication. They ensure integrity of the data from the wrongdoers. So, having strong password is that is transmitted. Collision free hash function is the one pivotal. As almost every website needs you to login and which can never have same hashes of different output. If a create a password, it’s tempting to use same password and b are inputs such that H (a) =H (b), and a ≠ b. for numerous websites like banks, shopping and social User chosen passwords shall not be used directly as networking websites. This way we are making our cryptographic keys as they have low entropy and information easily accessible to hackers. Hence, we need randomness properties [2].Password is the secret value from a strong application for password security and which the cryptographic key can be generated. Figure 1 management. In this paper, we are going to compare the shows the statics of increasing cybercrime every year. Hence performance of 3 key derivation algorithms, namely, there is a need for strong key generation algorithms which PBKDF2 (Password Based Key Derivation Function), can generate the keys which are nearly impossible for the Bcrypt and Scrypt. -

Milan Brož iii Acknowledgement I would like to thank my supervisor for his guidance and support, and also for his extensive contributions to the Cryptsetup open- source project. Next, I would like to thank my family for their support and pa- tience and also to my friends who were falling behind schedule just like me and thus helped me not to panic. Last but not least, access to computing and storage facilities owned by parties and projects contributing to the National Grid In- frastructure MetaCentrum, provided under the programme “Projects of Large Infrastructure for Research, Development, and Innovations” (LM2010005), is also greatly appreciated. v Abstract Key derivation functions are a key element of many cryptographic applications. Password-based key derivation functions are designed specifically to derive cryptographic keys from low-entropy sources (such as passwords or passphrases) and to counter brute-force and dictionary attacks. However, the most widely adopted standard for password-based key derivation, PBKDF2, as implemented in most applications, is highly susceptible to attacks using Graphics Process- ing Units (GPUs). -

Harden Zero Knowledge Password Proofs Against Offline Dictionary
Harden Zero Knowledge Password Proofs Against Offline Dictionary Attacks Gijs Van Laer Rono Dasgupta Aditya Patil [email protected] [email protected] [email protected] Matthew Green [email protected] December 12, 2016 Abstract Traditional authentication systems offer ease of use but the security they provide often proves to be inadequate. Hackers use means to gain access to company servers and steal entire databases of password hashes. These hashes are then subject to offline dictionary attacks resulting in the disclosure of millions of passwords. Such password breaches have become commonplace and have caused several major companies to face major losses. Password reuse is a common practice among users and a password breach disclosing a single password on a particular service could result in a user also losing access to their other accounts. Solutions such as multi-factor authentication add some level of security but do not completely solve the problem. There is a need to move towards stronger authentication schemes that do not compromise on ease of use, both for the user and the service provider. In this paper, we propose a novel authentication protocol that is proven hard against offline dictionary attacks. Our protocol implements a combination of a Zero Knowledge Password Proof and a sequentially memory hard hash function. In a concrete instan- tiation of the protocol, we use Schnorr's Zero Knowledge Password Proof combined with the Fiat-Shamir Heuristic for the Zero Knowledge Password Proof and scrypt for the sequentially memory hard hash function. We also describe a library implementing our protocol that we have developed along with an example web application that uses the library. -
