A message authentication code based on latin squares

, 1997
This is a proposal on the construction of a Message Authentication Code (MAC) based on Latin Squares. The design is inspired by Wegman-Carter construction which takes advantage of provable security. The MAC is described and its security is examined. It is also compared with other MACs and its advantages are shown.

Two-Level QR Code for Private Message Sharing and Document Authentication

IEEE Transactions on Information Forensics and Security, 2016
International audienceThe quick response (QR) code was designed for storage information and high-speed reading applications. In this paper, we present a new rich QR code that has two storage levels and can be used for document authentication.

Updatable Signatures and Message Authentication Codes

2021
Cryptographic objects with updating capabilities have been proposed by Bellare, Goldreich and Goldwasser (CRYPTO’94) under the umbrella of incremental cryptography. They have recently seen increased interest, motivated by theoretical questions (Ananth et al., EC’17) as well as concrete practical motivations (Lehmann et al., EC’18; Groth et al.

Approximate image message authentication codes

IEEE Transactions on Multimedia, 2001
This paper introduces approximate image message authentication codes (IMACs) for soft image authentication. The proposed approximate IMAC survives small to moderate image compression and it is capable of detecting and locating tampering. Techniques such as block averaging and smoothing, parallel approximate message authentication code (AMAC ...

Message Authentication with Manipulation Detection Code

1983 IEEE Symposium on Security and Privacy, 1983
In many applications of cryptography, assuring the authenticity of communications is as important as protecting their secrecy. A well known and secure method of providing message authentication is to compute a Message Authentication Code (MAC) by encrypting the message.

Vectorization of Poly1305 Message Authentication Code

2015 12th International Conference on Information Technology - New Generations, 2015
This paper describes software optimizations for the message authentication code Poly1305. We leverage the wide vectorization capabilities of the new AVX2 architecture, to speed up the authenticator generation on the latest x86_64 processors. In addition, we show how to apply vectorization for the future AVX-512 architecture to achieve a further speedup.

On the security of iterated message authentication codes

IEEE Transactions on Information Theory, 1999
Summary: The security of iterated message authentication code (MAC) algorithms is considered, and in particular, those constructed from unkeyed hash functions. A new MAC forgery attack applicable to all deterministic iterated MAC algorithms is presented, which requires on the order of \(2^{n/2}\) known text-MAC pairs for algorithms with \(n\) bits of ...

Throughput Optimization of the Cipher Message Authentication Code

2007 15th International Conference on Digital Signal Processing, 2007
A new algorithm for producing message authenticating code (MAC) 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 only someone who knows the secret key could be able to generate a valid MAC.
