Implementation of Dedicated Hardware for Encryption
Recently, the number of electronic devices handling confidential information has increased. In these devices, encryption is applied to protect the confidential information. Therefore, technologies to incorporate cryptographic circuits into these cards have become important. This paper proposes a new hardware dedicated to a typical cryptograph. In the proposed RC5 dedicated hardware, by introducing an architecture suitable for each operation used for the encryption, high-speed processing and area reduction can be realized. Experimental results of which proposed hardware architecture is implemented on FPGA proved the validity of the proposed one.
