Pipelined implementation of Camellia encryption algorithm

In modern communication networks, the security aspect is very important. Encryption algorithms are used to protect user communication from eavesdropping. Symmetric key algorithms must be used to achieve high speed secured communication. In this paper, we propose and evaluate the pipelined implementation of the Camellia encryption algorithm which has been approved for use by the ISO/IEC. Camellia algorithm achieves the same level of security as the AES while having similar hardware complexity.
