Abstract

The upcoming pervasive computing age will lead to an increased demand for security for applications ranging from RFIDs and smart cards to mobile devices. Lightweight cryptography is a key tool for building strong security solutions for pervasive devices. Due to the tight cost constraints of such extremely high-volume applications, efficient hardware and software implementations of cryptographic algorithms are of the utmost importance to realize the vision of pervasive computing. However, the computational complexity inherent in ciphers poses a major challenge. This article presents a selection of recently published lightweight cryptographic implementations and compares them to state-of-the-art results in the field. This survey covers recent hardware and software implementations of both symmetric and asymmetric ciphers.
