Abstract. At Eurocrypt 2005, Waters presented an identity based encryption (IBE) protocol which is secure in the full model without random oracle. In this paper, we extend Waters...
Abstract. We propose a variant of the “bonsai tree” signature scheme, a latticebased existentially unforgeable signature scheme in the standard model. Our construction offers ...
This paper presents a first example of secure identity based encryption scheme (IBE) without redundancy in the sense of Phan and Pointcheval. This modification of the Boneh-Frank...
We give the first proof of security for an identity-based encryption scheme in the quantum random oracle model. This is the first proof of security for any scheme in this model ...
