Tate Modern

Steven Galbraith

This talk concerns the Tate pairing and its applications in cryptography. I will cover some of the following topics: the mathematics behind the Tate pairing, its generalisation to higher-genus curves, implementation issues, the construction of suitable non-supersingular elliptic curves, the bit-security of keys obtained from pairing-based protocols and the hardness of the bilinear-Diffie-Hellman problem.
