Deniable encryption

It is broadly divided into two types: lockscreen ransomware and encryption ransomware (Microsoft Malware Protection Center). The former prevents access to files by using a full-screen message, while the latter encrypts files with a key known only to the attackers (Microsoft Malware Protection Center). In both cases, the…

Introduction Over the last couple of decades, the world as we know it has been transformed drastically. At the center of this transformation is technology, fueled by innovation and research. It is important to realize that the term technology encompasses all manner of innovations in every aspect and field of life; whether it is engineering, agriculture, manufacturing, etc. But how did the world come to be defined entirely by technology? When did this happen? A key constituent and catalyst of…

Penetration tests assesses the overall security. It is the process of attempting to gain access to resources without knowledge of specific user names, their passwords, or other normal means of access (similar to what an attacker would do). The big different between a penetration tester and an attacker basically is permission. A penetration tester will already have some permissions (such as an normal user account) in place from the owner or managers of the computing resources that are to be…

infrastructure is the combination of software, encryption technologies and services that enables enterprises to maintain the security of their business transactions on over the internet. It integrates digital certificates, public key cryptography and certification authorities into a complete enterprise-wide network security architecture. It is also defined as a set of roles, policies and procedures needed to create, revoke digital certificates and manage public-key encryption. It is used to bind…

MD5 is a calculation that is utilized to confirm information trustworthiness through the formation of a 128-piece message process from information input (which might be a message of any length) that is asserted to be as one of a kind to that particular information as a unique mark is to the particular person. Proposed where a vast record must be "compacted" in a safe way before being scrambled with a private key under an open key cryptosystem such as PGP. There are a lot of applications and we…

Government shouldn’t have an automatic right to read anyone’s private messages/information at any time. One pro of end-to-end encryption is that data is secured when it travels from a source to its destination. It also offers high flexibility for user in selecting a data to encrypt. Another pro is that we can easily integrate with the existing solution. We can just add an encryption/decryption layer to the existing solution. One problem is that the authentication of users may be an issue. To add…

2.3.1 Frequency attacks Techniques that are based on deterministic encryption are usually susceptible to frequency attacks. The party receiving the “so thought” secure encrypted data can perform a frequency analysis on selected fields in order to uncover the original data. For example, if the attacker has access to the demographic or census data of a particular population, he could calculate the frequency of a selected field and try to map it to the encrypted data frequencies to deduce a…

because obviously different countries laws contradict other countries’ laws. So in order to resolve this policy vacuum, the American government can’t ask a company or business sending encrypted data to other countries to provide a back-door in their encryption. Therefore, it would not be morally right for America to ask companies or individuals to provide back-doors in data that goes outside of…

In most cases, this is recorded real communication. with a flawed encryption algorithm you can use that to break the rest of the encryption. For example: with the old pkzip encryption method. In this case if you had any of the unencrypted files in the archive, you could use that to obtain the key to break the rest. Plain text attack is the other type of attack for cryptanalysis…
