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 ...

This standard specifies hash algorithms that can be used to generate digests of messages. The digests are used to detect whether messages have been changed since the digests were generated. This ...

The National Institute of Standards and Technology (NIST) has opened a competition to develop a new cryptographic "hash" algorithm, a tool that converts a file, message or block of data to a short ...

Louvain‐la‐Neuve, Belgium, May. 24, 2017 – Barco Silex, leading provider of IP cores for embedded security, has added the new SHA-3 hashing functions to its extensive offering of IP blocks. Hashing ...

Networks utilize encryption in many ways: during user authentication, to keep data confidential, to guarantee the integrity of information and to ensure non-repudiation. In fact, we now use encryption ...

Previous articles (Part one, Part two) in this series on implementing VPN gateways using Cisco routers discussed the IPsec protocol and basic IPsec VPN connection models. Now we'll learn how to ...

Security researchers have achieved the first real-world collision attack against the SHA-1 hash function, producing two different PDF files with the same SHA-1 signature. This shows that the algorithm ...
