Symmetric key encryption, also known as secret key encryption, is a type of encryption where the same key is used to encrypt ... works by applying a mathematical function, called an algorithm ...

program1.h - Header file for global variables, class objects, and functions ... and the resulting block is 64 bits. This is a symetric key system so the encryption and decryption processes are the ...

We introduce a symmetric block encryption scheme based on a secret key which is a table of strong generators of a permutation group. We discuss how the proposed scheme can be adopted to be used as an ...

Having only one key to serve both the encryption and decryption functions ... block ciphers. Block ciphers encrypt data in chunks (blocks), whereas stream ciphers encrypt data one bit at a time. So, ...
