Brief Background in Security and Cryptography

Abstract

This chapter briefly provides necessary background knowledge in security and cryptography. It provides a brief introduction into symmetric-key and asymmetrickey cryptography, introduces several cryptographic primitives, and provides the basics in Trusted Computing and cryptanalysis. This chapter further gives brief descriptions of several cryptographic schemes that are important in the automotive context. It lastly gives some rough ideas for execution performance and required resources for cryptographic implementations in hardware and software. Parts of this chapter are based on published research in [AES⁺07, EGP⁺07, WWW07].
