The continuous increase in demand for security in electronic systems and communication systems which lacks a secure architecture has resulted in the need to provide cryptography architecture with high secure core. The hardware implementation of the cryptography core which incorporates multiple algorithm for security purpose was already developed but if the architecture is capable of switching between the algorithms used for encryption/decryption as controlled by the host computer dynamically, then the security over the data path will be increased by making the attempt for hacking too difficult. The switching between heterogeneous algorithms will also increase the confusion level. This proposed architecture implements three symmetric algorithms namely the standard AES, standard DES and proposed Modified DES (MDES) algorithms.
