Efficient Message Authentication Codes with Combinatorial Group Testing
Message authentication code Combinatorial group testing Data corruption
2019/4/23
Message authentication code, MAC for short, is a symmetric-key cryptographic function for authenticity. A standard MAC verification only tells whether the message is valid or invalid, and thus we can ...
Universal Forgery with Birthday Paradox: Application to Blockcipher-based Message Authentication Codes and Authenticated Encryptions
Universal forgery birthday attack CBC-MAC
2017/7/6
We also propose another some generic universal forgery attacks using collision finding with structural input messages, by birthday paradox in the classic setting. Since our attacks are based on the co...
While standard message authentication codes (MACs) guarantee authenticity of messages,
they do not, in general, guarantee the anonymity of the sender and recipient. For example it may be
easy for an...
Authentication Codes Based on Resilient Boolean Maps
Authentication Schemes Resilient Maps Finite Fields
2016/1/8
We introduce new constructions of systematic authentication codes over finite fields and Galois rings. One code is built over finite fields using resilient functions and it provides optimal impersonat...
Design and Analysis of Information-Theoretically Secure Authentication Codes with Non-Uniformly Random Keys
authentication code non-uniformly random key information-theoretic security
2016/1/3
The authentication code (A-code) is the one of the most fundamental cryptographic protocols in information-theoretic cryptography, and it provides information-theoretic integrity or authenticity, i.e....
Message Authentication Codes Secure against Additively Related-Key Attacks
message authentication code related-key attack
2013/4/18
Message Authentication Code (MAC) is one of most basic primitives in cryptography. After Biham (EUROCRYPT 1993) and Knudsen (AUSCRYPT 1992) proposed related-key attacks (RKAs), RKAs have damaged MAC's...
Multiple forgery attacks against Message Authentication Codes
Multiple forgery attacks Message Authentication Codes MACs
2009/2/9
Some message authentication codes (MACs) are vulnerable to multiple forgery attacks, in which an attacker can gain information that allows her to succeed in forging multiple message/tag pairs. This pr...
SOME NEW CONSTRUCTIONS OF CARTESIAN AUTHENTICATION CODES FROM SYMPLECTIC GEOMETRY
Cartesian authentication code construct
2007/8/7
Two new constructions of Cartesian authentication codes from symplectic geometry are presented and their size parameters are computed.
