In cryptography, a universal hashing message authentication code, or UMAC, is a message authentication code (MAC) calculated using universal hashing, which involves choosing a hash function from a class of hash functions according to some secret (random) process and applying it to the message. The resulting digest or fingerprint is then ...

Abstract This specification describes how to generate an authentication tag using the UMAC message authentication algorithm. UMAC is designed to be very fast to compute in software on contemporary uniprocessors. Measured speeds are as low as one cycle per byte.

UMAC is a message authentication code: an algorithm for generating authentication tags, which are used to ensure the authenticity and integrity of transmitted messages. UMAC is the fastest message authentication code that has been reported on in the cryptographic literature.

This paper describes a new message authentication code, UMAC, and the theory that lies behind it. UMAC has been designed with two main goals in mind: Extreme speed. We have aimed to create the fastest MAC ever described, and by a wide margin. We are speaking of speed with respect to software implementations on contemporary general-purpose ...

本规范描述了如何使用umac消息身份验证算法生成身份验证标记。umac被设计为在当代单处理器上以软件进行计算的速度非常快。测量的速度低至每字节一个周期。umac依赖于32位和64位数字的加法和32位数字的乘法，这些操作深受当代机器的支持。

2025年2月20日 · UMAC（Universal Message Authentication Code）是一种高效的消息认证码算法，它利用加密哈希函数与伪随机函数相结合来提供数据的完整性验证和认证。 UMAC 在设计上注重算法的速度和简洁性，特别适用于处理大量数据的场景，比如网络通信中的数据包校验。 UMAC 的核心设计目标是实现高速的消息认证。 它在保证安全性的同时，通过减少对计算资源的需求来达到较高的性能。 UMAC 使用短的认证标签，从而减少了需要发送和接收的数据量， …

2024年7月16日 · umac是基于通用哈希的一种高效且安全的消息认证码算法，旨在提供数据完整性保护和源认证。 它在IETF的草案中不断发展和完善，反映了密码学界对安全通信的持续追求。
