The key length used for a cryptographic protocol determines the highest security it can offer.
If the key is found or 'broken', the security is undermined. Thus, key lengths must be chosen …

One of the most important classes of cryptographic algorithms in current use is the class of
cryptographic hash functions. Hash functions are ubiquitous in today's IT systems and have …

Compare-by-hash is the now-common practice used by systems designers who assume that
when the digest of a cryptographic hash function is equal on two distinct files, then those …

We present an approach to design cryptographic hash functions that builds on and improves
the one underlying the Panama hash function. We discuss the properties of the resulting …

In this article, the RIPEMD-160 hash function is studied in detail. To analyze the hash
function, we have extended existing approaches and used recent results in cryptanalysis …

This paper describes a new software-efficient 256-bit hash function, FORK-256. Recently
proposed attacks on MD5 and SHA-1 motivate a new hash function design. It is designed …

HMAC is one of the most famous keyed hash functions, and widely utilized. In order to
design secure hash functions, we often use PGV construction consisting of 64 schemes …

6,028,937 A* 2/2000 Tatebayashi et a1......... 713/169 dance with other embodiments of the
invention, in order to protect against a security compromise at the server, the server is not in …

Hash functions are special cryptographic algorithms, which are applied wherever message
integrity and authentication are critical. Implementations of these functions are cryptographic …

Recent breakthroughs in cryptanalysis of standard hash functions like SHA-1 and MD5 raise
the need for alternatives. A credible alternative to for instance SHA-1 or the SHA-2 family of …
