Reconfigurable crypto processor design of encryption algorithms operation modes methods and FPGA integration

Security is a crucial issue for the provision of net or communications. Encryption algorithms are used to ensure security in the transmission channel. In addition to the common way of operation of ECB, the encryption algorithms have to perform efficiently in a variety of operation modes, for alternative security applications and purposes, these modes are CBC, CFB, OFB, CTR and CBC-MAC. In this paper, a multi-mode operation architecture is proposed. In addition, based on a full-rolling architecture the most well known encryption algorithms have been implemented.
