Nowadays, more than ever, security is considered to be critical issue for all electronic transactions. This is the reason why security services like those described in IPSec are mandatory to IPV6 which will be adopted as the new IP standard the next years. In fact E.U. has set the target of moving to IPv6 for about 25% of European e-infrastructures in 2010.(More)
High-throughput and area-efficient designs of hash functions and corresponding mechanisms for Message Authentication Codes (MACs) are in high demand due to new security protocols that have arisen and call for security services in every transmitted data packet. For instance, IPv6 incorporates the IPSec protocol for secure data transmission. However, the(More)
Many cryptographic primitives that are used in cryptographic schemes and security protocols such as SET, PKI, IPSec, and VPNs utilize hash functions, which form a special family of cryptographic algorithms. Applications that use these security schemes are becoming very popular as time goes by and this means that some of these applications call for higher(More)
