The Order of Encryption and Authentication for Protecting Communications (Or: How Secure Is SSL?)?
The Order of Encryption and Authentication for Protecting Communications (Or: How Secure is SSL?)? Hugo Krawczyk?? Abstract. We study the question of how to generically compose sym- metric encryption and authentication when building \secure channels" for the protection of communications over insecure networks. We show that any secure channels protocol designed to work with any combina- tion of secure encryption (against chosen plaintext attacks) and secure MAC must use the encrypt-then-authenticate method. We demonstrate this by showing that the other common methods of composing encryp- tion and authentication, including the authenticate-then-encrypt method used in SSL, are not generically secure. We show an example of an en- cryption function that provides (Shannon's) perfect secrecy but when combined with any MAC function under the authenticate-then-encrypt method yields a totally insecure protocol (for example, ¯nding passwords or credit card numbers transmitted under the protection of such protocol becomes an easy task for an active attacker). The same applies to the encrypt-and-authenticate method used in SSH. On the positive side we show that the authenticate-then-encrypt method is secure if the encryption method in use is either CBC mode (with an underlying secure block cipher) or a stream cipher (that xor the data with a random or pseudorandom pad). Thus, while we show the generic security of SSL to be broken, the current practical implementations of the protocol that use the above modes of encryption are safe. 1 Introduction The most widespread application of cryptography in the Internet these days is for implementing a secure channel between two end points and then exchanging information over that channel. -

AISHWARYA1 K.DEVIKA RANI DHIVYA*2 III MSc (SS), Assistant Professor, Department of CA & SS, Department of CA & SS, Sri Krishna Arts and Science College, Sri Krishna Arts and Science College, Coimbatore, Tamil Nadu, Coimbatore, Tamil Nadu, India India ABSTRACT: Credit card is a small plastic card issued by a bank, building society, etc., allowing the holder to purchase goods or services on credit. Debit card is a card allowing the holder to transfer money electronically from their bank account when making a purchase. The use of credit cards and debit cards are increasing day by day. People are relying more on both cards nowadays than in the previous days. As credit cards and debit cards becomes the most popular mode of payment for both online as well as regular purchase, cases of fraud associated with it are also rising. In real life, fraudulent transactions are scattered with genuine transactions and simple pattern matching techniques are not often sufficient to detect those frauds accurately. In this project the process of Cryptography has been followed, it is one of the most important security technologies which used to secure the data transmission and the data itself. -
Cyber Risks to Public Safety: Ransomware, September 2020
CYBER RISK TO PUBLIC SAFETY: RANSOMWARE RANSOMWARE IMPACTS ON PUBLIC SAFETY If you are experiencing a ransomware attack, please go directly to page 3 for incident reporting resources Ransomware is a type of malicious software that encrypts information stored on hard drives or network drives and disrupts access to compromised devices or networks. Ransomware applications threaten to erase, lock, or otherwise damage compromised drives and data unless payment is provided. Ransomware programs often elicit a sense of urgency (e.g., a short deadline for payment) to encourage affected organizations to pay. Ransomware applications may threaten to escalate demands (e.g., increase payment) if payment is not provided quickly. Even when payments are provided, malicious actors may steal sensitive information, default on agreements to restore access, or conduct follow-up cyberattacks. While ransomware typically aims to extort money from organizations, malicious actors may also target public safety agencies or critical infrastructure with the goal of disrupting emergency response capabilities.1, 2 Figure 1. Recent Ransomware Attack Statistics Ransomware can have a significant impact on public safety operations, including services provided by fire, emergency medical services, law enforcement, emergency communication centers/public safety answering points, and other public safety partners. Disruptions to public safety operations directly and negatively impact the health and safety of the communities they serve. For example, delays dispatching fire and emergency medical services may lead to increased loss of life and property damage. Malicious actors may target public safety agencies specifically to exploit these negative outcomes, creating a strong sense of urgency to accommodate perpetrator demands. Public safety agencies are highly encouraged to plan and prepare for a ransomware event to mitigate service disruptions, conduct effective response operations, and ensure rapid recovery. -
Ransomware Is Here: What You Can Do About It?
WHITEPAPER Ransomware is Here: What you can do about it? Overview Over the last few years, ransomware has emerged as one of the most devastating and costly attacks in the hacker arsenal. Cyber thieves are increasingly using this form of attack to target individuals, corporate entities and public sector organizations alike by holding your system or files for ransom. Unlike other forms of cyber theft that often involve stolen financial or healthcare information, ransomware cuts out the middleman. In cases where an attacker steals health or financial documents, they must sell them on to third parties to make money. As far as ransomware is concerned, the money comes directly from the victim. Ransomware is a quickly growing threat vector. According to the FBI’s Internet Crime Complaint center (IC3), infected users made complaints about ransomware 2,453 times in 2015—nearly double the figure for 2014. What’s more, these figures most likely represent only the tip of the iceberg, as many users pay their ransom without making a report to the authorities. A recent survey conducted by a Cyber Security Research Center at the University of Kent found that over 40% of those infected with CryptoLocker actually agreed to pay the ransom demanded, which is a big incentive for hackers to target more systems. Lastly, hackers are rapidly iterating both malware and distribution techniques. In early Q2 of 2016, a new variant of ransomware, known as CryptXXX, emerged on the scene. This program is packed in such a way that users and antivirus software may initially confuse it for a Windows DLL file. -
Internet Security
Internet Security Personal It’s second nature for us to access the internet throughout the day. Our smartphones, laptops and desktops have essentially become an extension of ourselves. Just like a seatbelt in a car or a helmet on a bike, we all need some type of internet security to protect ourselves from potential hazards. Here are a few internet security tips to ensure you’re safety online. Shop Safely: Check for the padlock: It’s important when shopping online to make sure the site you’re on uses an SSL (secure sockets layer) certificate encryption. You can easily identify a site that uses this certificate by finding an image of a padlock in one of two places: either the status bar or the bottom of your web browser. This encryption ensures your credit card information, email or other personal information is protected from hackers. Phishing Protection: Periodically, you may receive fraudulent email messages appearing to come from a valid source. These emails are generally referred to as SPAM or 'Phishing' messages. To protect yourself and your family from phishing scams: • Be suspicious of any unsolicited emails asking for personal information. You should always be very suspicious when asked for personal information, especially when asked by companies or organizations that should already have such information. If you need to update your information call 1.800.746.4726 to speak to a Customer Service Representative. • Always report fraudulent or suspicious email. Reporting such instances will help get these "bad guys" tracked down. You can report any suspicious emails like these via the Spam button within webmail. -

Security, Encryption, and Certificates FAQ
Security, Encryption, and Certificates FAQ Overview In Security Center 5.4, several new capabilities will be added that further strengthen the security of the platform itself, as well as the privacy of data. The aim is to prevent unauthorized access to stored and transmitted messages and data, as well as prevent attacks through the use of stronger encryption and authentication mechanisms. With growing demand for privacy, new capabilities in Security Center 5.4 will strengthen Genetec’s position and overall value proposition. This FAQ addresses some of the most common questions in relation to the new capabilities of Security Center: Encryption, Authentication, and Digital Certificates. These concepts are first described in generic terms; the FAQ then outlines how these new measures are used within Security Center 5.4. Encryption vs. Authentication vs. Authorization What is the difference between encryption, authentication, and authorization? Encryption is used to encrypt data so that only authorized users can see it. Authentication determines whether an entity is who they claim to be, eg. in the case of an individual, it is usually based on a username/password combination. Authentication does not actually say anything about what someone is authorized to do or has the right to do. o Client-side authentication uses username/password combinations, tokens (dual authentication), and other techniques. o Server-side authentication uses certificates to identify trusted third parties. Authorization is the function of specifying the rights, eg. defining the access rights someone has over a set of recourses such as a private data, computing resources, or an application. When users log into a Security Center system, what they are allowed or authorized to do depends on the set of privileges assigned to them by administrators. -
