Case study: integrated design of RC5 encryption

With the wireless communications coming to homes and offices, the need to have a secure data transmission is of utmost importance. Today, it is important that information is sent confidentially over the network without fear of hackers or unauthorized person having access to it; this makes security implementation in networks a crucial demand. RC5 is an encryption algorithm which is widely used in wireless transport layer security. In this paper, RC5 system architecture is investigated and a high-performance design in terms of encryption throughput is introduced. The proposed architecture designed with a pipeline technique achieves a higher throughput. In this study, over 80% increase was reported in the encryption throughput as compared to related work.
