IPsec incorporates several cryptographic operations to ensure message authenticity, data integrity, and sender nonrepudiation. In this section we will describe the mechanics of these cryptographic ...

Abstract: Presents a new proposed message digest (MD) algorithm. Many of its characteristics (application domain, performance and implementation structure) are similar to those of the MD4 family of ...

An algorithm that transforms a given amount of data (the "message") into a fixed number of digits, known as the "hash," "digest" or "digital fingerprint." Hash functions are a fundamental component in ...

A digital signature, an asymmetric cryptography is designed using VHDL. The implementation has a Message Digest block and a RSA block. Implemented Digital Signature Algorithm on a Spartan 3 FPGA board ...
