Capacity Theory on Algebraic Curvesextra information called a .. It is desirable that the sketch reveals little information about the biometric templates even in the worst case (i.e., the . should be low). The main difficulty is that many biometric templates are represented as points in continuous domains with unknown distributions,

We have thus designed a new algorithm for the construction of CM invariants of genus 2 curves, using 2-adic lifting of an input curve over a

This is the case in particular of Koblitz curves and supersingular curves, where scalar multiplication can now be achieved in .(log.) curve additions..Previous literature dea

Introduction and Research Questions,, we extend Waters’ IBE protocol to a hierarchical IBE (HIBE) protocol which is secure in the full model without random oracle. The only previous construction in the same setting is due to Waters. Our construction improves upon Waters’ HIBE by significantly reducing the number of public parameters.

Our forward-secure broadcast encryption schemes have small ciphertext and private key sizes, in particular, independent of the number of users in the system. One of our best two constructions achieves ciphertexts of constant s

However, despite extensive study, the most efficient provably secure RSA-based generators output asymptotically only at most .(log.) bits per multiply modulo an RS

Capacity-Building in a Post-SARS World,rther arguments in support of the security of OAEP. We first show that partial instantiations, where one of the two random oracles used in OAEP is instantiated by a function family, can be provably secure (still in the random oracle model). For various security statements about OAEP we specify suffi
