Thanks to an appropriate mix of theoretical foundations and practical considerations, we designed several hardware coprocessors and software libraries to compute the cryptographic Tate pairing at the level of security of AES-128 over ordinary and supersingular elliptic curves. We also proposed a novel pairing algorithm over supersingular genus-2 hyperelliptic curves. In order to design a coprocessor for pairing-based cryptography, it is however necessary to consider the implementation of auxiliary cryptographic primitives, such as hash functions. Since the NIST has opened a public competition to develop a novel cryptographic hash function (SHA-3), we decided to contribute to the selection process by designing compact architectures for several candidates.

由于理论基础和实际考虑的适当结合，我们设计了几个硬件协处理器和软件库来计算普通和超奇异椭圆曲线上的密码Tate配对，其安全性达到了AES-128的水平。我们还提出了一个新的超奇异亏格2超椭圆曲线上的配对算法。然而，为了设计用于基于配对的密码术的协处理器，有必要考虑诸如散列函数之类的辅助密码原语的实现。由于NIST已经公开竞争开发一种新的加密散列函数(SHA-3)，我们决定通过为几个候选者设计紧凑的体系结构来为选择过程做出贡献。
