Formal Analysis and Systematic Construction of Two-Factor Authentication Scheme (Short Paper)particular, we show that a secure password based key exchange protocol can be transformed efficiently to a smartcard and password based two-factor authentication scheme provided that there exist pseudorandom functions and collision-resistant hash functions.

Notorious

A Construction for General and Efficient Oblivious Commitment Based Envelope Protocols satisfies a predicate, we have an OCBE protocol for that predicate with constant additional cost. Compared with previous OCBE protocols, our construction is more general, more efficient, and has wide applicability.

Distributed Credential Chain Discovery in Trust Management with Parameterized Roles and Constraints ttom-up strategy for a particular part of the proof; this enables the algorithm to touch only those credentials that are related to the query, which are likely to be a small fraction of all the credentials in the system.

Invigorate

Efficient Protocols for Privacy Preserving Matching Against Distributed Datasetsmputation and communication costs of our PPSI protocol decrease by 81% and 17% respectively, and the computation and communication costs of our PPSM protocol decrease by 80% and 50% respectively. In practical utilities both of our protocols save computation time and communication bandwidth.
