Abstract

See full text

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 (m1, t1) and computing, in the computer processor, a first hashed message-tag pair H(m1, t1), 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 (m2, t2) and computing, in the computer processor, a second hashed message-tag pair H(m2, t2). The method comprises computing, in the computer processor, an aggregated MAC (At1) by an addition operation, as follows: At1=(H(m1, t1)+H(m2, t2)) modulo N, where N is a natural number equal to two or greater.
