Abstract
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
