Message authentication algorithm based on fully homomorphism MAC method
There are many problems of security and authentication in communication channel with data transmission. After studying the fully homomorphism encryption and message authentication code(MAC) algorithm, this paper presents a scheme of message ...

Message Authentication Code over a wiretap channel [PDF]
Message Authentication Code (MAC) is a keyed function $f_K$ such that when Alice, who shares the secret $K$ with Bob, sends $f_K(M)$ to the latter, Bob will be assured of the integrity and authenticity of $M$. Traditionally, it is assumed that the channel is noiseless. However, Maurer showed that in this case an attacker can succeed with probability $2^

Differential Attack on Message Authentication Codes [PDF]
We discuss the security of Message Authentication Code (MAC) schemes from the viewpoint of differential attack, and propose an attack that is effective against DES-MAC and FEAL-MAC. The attack derives the secret authentication key in the chosen plaintext scenario.

On authentication codes based on orthogonal tables
The authentication codes resistant to messages imitation and substitution are investigated. The case when the probabilities of imitation and substitution reach the lower limits has been highlighted. Such authentication codes are called optimal.

Digital signatures over HMAC entangled chains
In this work we present a new digital signature method based on hash chains and the hash message authentication code (HMAC). Unlike Blockchain technology, our approach establishes that the database of transactions is distributed among users, so each one ...

Quantum-Secure Message Authentication Codes [PDF]
We construct the first Message Authentication Codes (MACs) that are existentially unforgeable against a quantum chosen message attack. These chosen message attacks model a quantum adversary’s ability to obtain the MAC on a superposition of messages of its choice.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Novel Hardware Implementation of the Cipher Message Authentication Code
A new algorithm for producing message authenticating codes (MACs) was recently proposed by NIST. The MAC protects both a message's integrity—by ensuring that a different MAC will be produced if the message has changed—as well as its authenticity because ...
