In this research the security issues are discussed for securing big data. Encryption algorithms play an essential part to secure information. This paper demonstrates analysis of well-known block cipher CAST-256 and its modified version using modified S-Box and key generator. In this research the implementation of the modified CAST cryptography algorithm was discussed. It was worked dynamically on...
Today, information has become an important resource and so is its security. Many scientists attempted to use new methods inspired from DNA bio-techniques in the field of cryptography and steganography. The idea of using DNA cryptography has been specified as possible technology that gets a new hope for unbreakable algorithms as traditional cryptographic systems are now vulnerable to certain attacks...
