Incentivizing Outsourced Computation
We describe different strategies a central authority, the boss, can use to distribute computation to untrusted contractors. Our problem is inspired by volunteer distributed computing projects such as SETI@home, which outsource computation to large numbers…

Two-dimensional mod p Galois representations attached to modular forms
Classical newforms are cusp forms on congruence subgroups of SL(2,Z) that are eigenvectors for the Hecke operators. These modular forms give rise to two-dimensional representations of the absolute Galois group of the rational field. Conversely,…

Deterministic Encryption: Theory and Applications
The focus of the talk is deterministic public-key encryption schemes. Besides being interesting from theoretical and historical perspectives, the deterministic encryption primitive has applications to fast and secure search on remote data. We study several…
