The Algorithm Developed by NIST, the AES algorithm is a complex cryptographic algorithm. Figure 1 shows the typical data flow for one “round” of the algorithm. For a 128-bit key, there are 10 rounds.

• AES (Advanced Encryption Standard): AES is a symmetric encryption algorithm widely used in government and industry. It offers key lengths of 128, 192 and 256 bits, providing strong security.

This paper proposes a high-throughput implementation of AES (Advanced Encryption Standard) supporting encryption and decryption with 128-bit cipher key.

A New Hardware Approach While existing architectures provide mechanisms for improving the performance of AES encryption, they still fall short in providing the cycle counts required for ...
