Popis: 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 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. This proposed architecture implements two symmetric algorithms namely the standard DES and complex DES (CDES) algorithms. Representing these algorithms in the functional block level and also using the new concept of common S-Box , results in operations that are common to all the two algorithms, thus there is an area reduction of 14.5% in cryptography core with 2 S-Boxes rather than using 11 S-Box.
