CAESAR Hardware API

In this paper, we define the CAESAR hardware Application Programming Interface (API) for authenticated ciphers. In particular, our API is intended to meet the requirements of all algorithms submitted to the CAESAR competition. The major parts of our specification include: minimum compliance criteria, interface, communication protocol, and timing characteristics supported by the core. All of them have been defined with the goals of guaranteeing (a) compatibility among implementations of the same algorithm by different designers, and (b) fair benchmarking of authenticated ciphers in hardware

Abstract—cryptographic devices have found their way into a wide range of application and the topic of their security has reached great research importance. It has been proved that encryption device leaks information, which can be exploited by various attacks such as power analysis, timing analysis and electro-magnetic radiation. Differential power analysis is a powerful and efficient cryptanalytic technique which extracts information on secret keys by monitoring instantaneous power consumption of crypto processor and collecting the traces over a series of acquisitions.. The focus of our project is to analyze how a crypto-processor (a smart card) implementing AES reveals information against Differential Power Analysis attacks
