Alice and Bob possess sequences xn and yn respectively and would like to compute d(xn , yn ) where d(., .) is a distortion measure. However, Alice and Bob do not trust each other ...
A (t, n) threshold signature scheme allows t or more group members to generate signatures on behalf of a group with n members, while any t−1 or less members cannot do the same th...
In this paper, a practical and secure e-mail system (called “PractiSES”) that performs public key distribution and management in a unique way is proposed. PractiSES is a networ...
Pass observed that universal composable zero-knowledge (UCZK) protocols in the common reference string (CRS) model, where a common reference string is selected trustily by a truste...
We propose a new cryptographic primitive called oblivious signaturebased envelope (OSBE). Informally, an OSBE scheme enables a sender to send an envelope (encrypted message) to a ...
