My research interests are reflected in my papers on cryptographic protocols for electronic voting, electronic payment, and secure multiparty computation, on amortized data structures and on some other algorithms.
See also these Lecture Notes Cryptographic Protocols and matching Lecture Slides Cryptographic Protocols (Handout version without animations), with extensive coverage of Sigma-protocols and threshold cryptography.
