Compact Proofs of Retrievability
In a proof-of-retrievability system, a data storage center must prove to a verifier that he is actually storing all of a client’s data. The central challenge is to build systems that are both efficient and…

Singular Moduli
The values of the elliptic modular function j at imaginary quadratic numbers τ are called singular moduli. They are of fundamental importance in the study of elliptic curves and in algebraic number theory, including the…
