Abstract
Method of producing an aggregated message authentication code (MAC). The method comprises generating or receiving, in a computer processor, a first message and its first MAC tag (m, t) and computing, in the computer processor, a first hashed message-tag pair H(m, t), where H is a cryptographic hash function. The method comprises generating or receiving, in the computer processor, a second message and its second MAC tag (m, t) and computing, in the computer processor, a second hashed message-tag pair H(m, t). The method comprises computing, in the computer processor, an aggregated MAC (At) by an addition operation, as follows: At=(H(m, t)+H(m, t)) modulo N, where N is a natural number equal to two or greater.
