The different algorithms like AES, DES and triple DES achieve more security but it takes more time for encryption and decryption files. These algorithm increases the complexity of the algorithm. In ...

The more unintelligible the encrypted image, the more secure it is. This paper proposes a method to encrypt and decrypt images with the help of linear feedback shift registers (LFSR). An LFSR produces ...

For example: A weak cipher is defined as an encryption/decryption algorithm that uses a key of insufficient length. Using an insufficient length for a key in an encryption/decryption algorithm opens ...
