Abstract

Symmetric key cryptography is a common cryptographic technique using the same key at both the transmitter and receiver side. The main advantage of symmetric key encryption is its less computational cost compared to its counterpart-public key encryption. In this work a new symmetric key encryption scheme is proposed. This proposed algorithm provides new step to avoid shortcomings. We use some famous algorithms to encrypt a data as follows. At first, we create new algorithm in order to provide security issue and time constraint of operation then we combine AES and CAST-128 algorithm, then we encrypt data using the proposed algorithm. This can enhance the security and complicates the Encryption. And the major advantage of this algorithm is key reusability. In this paper we provide both the encryption and decryption that supports in real time application and algorithm has a practical value.
