In order to ensure data integrity of continuously provided signals often a compression function is needed in combination with encryption. This compression can be performed by a cryptographic hash function, which needs a lot of circuitry and/or memory and is therefore not favored for high volume and cost sensitive automotive applications. For some specific applications it is proposed to replace the hash function by a low cost nonlinear multiple input signature register circuitry. The construction of such a structure, its properties and limitations are presented in this paper.
