An Introduction to Block Cipher Algorithms and Their Applications in Communication SecurityAdded by Papergrl
Description:
Block Cipher algorithms are a type of Symmetric Key Encryption. Symmetric Key encryption is a key-based encryption in which the same key that is used to encrypt sensitive data is used to decrypt the sensitive data. The disadvantage of Symmetric Key encryption is that it only requires the person wishing to break the encryption to obtain only one key. For this reason, the key must be protected and secured. The key is often called a secret key.
