Abstract. Whereas encryption schemes withstanding passive chosenplaintext attacks (CPA) can be constructed based on a variety of computational assumptions, only a few assumptions a...

Abstract. In this paper we present a simpler construction of a publickey encryption scheme that achieves adaptive chosen ciphertext security (CCA2), assuming the existence of trapd...

We propose two constructions of chosen-ciphertext secure identity-based encryption (IBE) schemes. Our schemes have a security proof in the standard model, yet they offer performan...

In a threshold broadcast encryption scheme, a sender chooses (ad-hoc) a set of n receivers and a threshold t, and then encrypts a message by using the public keys of all the recei...

We propose a scheme for electronic cash based on symmetric primitives. The scheme is secure in the framework for universal composability assuming the existence of a symmetric CCA2-...
