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 ...

Chaotic hash functions represent a cutting‐edge convergence between nonlinear dynamics and cryptographic science. These functions employ chaotic maps—mathematical systems that exhibit extreme ...

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 ...

Part I introduced some of the challenges in the way of the public understanding of how Bitcoin works, and summarized the strategic roles of the open source software model, peer-to-peer networking, and ...

The National Institute of Standards and Technology is seeking comments from the public on it’s latest cryptographic hash function, SHA-3. The National Institute of Standards and Technology (NIST) is ...

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 ...

Understanding Bitcoin is a one-way hash function should make sense because a hash function cannot be reversed. Once you understand that, it is hard to go back to thinking otherwise. The secure hash ...

The nice thing about standards is that there are so many to choose from. And if you really don't like all the standards you just have to wait another year until the one arises you are looking for. -- ...
