Hash Algorithm In Verification Of Certificate Data Integrity And Security
Aptisi Transactions on Technopreneurship, 2021 The hash function is the most important cryptographic primitive function and is an integral part of the blockchain data structure. Hashes are often used in cryptographic protocols, information security applications such as Digital Signatures and message ...

Random Structures & Algorithms, 2000 AbstractWe define a family of functions F from a domain U to a range R to be dispersing if for every set S ⊆ U of a certain size and random h ∈ F, the expected value of ∣S∣ – ∣h[S]∣ is not much larger than the expectation if h had been chosen at random from the set of all functions from U to R.We give near‐optimal upper and lower bounds on the size of ...

Trigonometric words ranking model for spam message classification
IET Networks, EarlyView., 2022 Abstract The significant increase in the volume of fake (spam) messages has led to an urgent need to develop and implement a robust anti‐spam method. Several of the current anti‐spam systems depend mainly on the word order of the message in determining the spam message, which results in the system's inability to predict the correct type of message when

Extended integer tent maps and dynamic hash function
Tongxin xuebao, 2010 Based on the analysis of uniform distribution property of the extended integer tent maps,a novel dynamic hash function with the output length of 160bit was constructed.In addition,the MD structure was improved so that the capacity of collision resistance

A Fast Single-Key Two-Level Universal Hash Function
IACR Transactions on Symmetric Cryptology, 2017 Universal hash functions based on univariate polynomials are well known, e.g. Poly1305 and GHASH. Using Horner’s rule to evaluate such hash functionsrequire l − 1 field multiplications for hashing a message consisting of l blocks where each block is one ...

Cryptanalysis of the 10-Round Hash and Full Compression Function of SHAvite-3-512 [PDF]
, 2010 In this paper, we analyze SHAvite-3-512 hash function, as proposed for round 2 of the SHA-3 competition. We present cryptanalytic results on 10 out of 14 rounds of the hash function SHAvite-3-512, and on the full 14 round compression function of SHAvite ...
