The sender’s unique information should be used in a signature; It should be easy to create a signature; It should be impossible to falsify a signature computationally; A signature should be small.

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 ...

Security pros often ask about the weaknesses of the Message-Digest version 5 algorithm (MD5) and whether it should still be used. MD5 is a cryptographic one-way hash function that produces a value ...

The original author of the MD5 password hash algorithmhas publicly declared his software end-of-life and is "no longer considered safe" to use on commercial websites. This comes only a day after a ...

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 ...
