—Security protocol design is a creative discipline where the solution space depends on the problem to be solved and the cryptographic operators available. In this paper, we exami...

The notion of concurrent signatures was recently introduced by Chen, Kudla and Paterson. In concurrent signature schemes, two entities can produce two signatures that are not bindi...
In undeniable signature schemes, zero-knowledgeness and non-transferability have been identified so far. In this paper, by separating these two notions, we show the first 3-move ...
Signcryption [35] is a public key primitive that achieves the functionality of both an encryption scheme and a signature scheme simultaneously. It does this more efficiently than a...
We give new methods for generating and using “strong trapdoors” in cryptographic lattices, which are simultaneously simple, efficient, easy to implement (even in parallel), a...
