We extend the concept of key encapsulation mechanisms to the primitives of ID-based and certificateless encryption. We show that the natural combination of ID-KEMs or CL-KEMs with ...

We present a new methodology for proving security of encryption systems using what we call Dual System Encryption. Our techniques result in fully secure Identity-Based Encryption ...

Abstract. Proofs of security protocols typically employ simple abstractions of cryptographic operations, so that large parts of such proofs pendent of cryptographic details. The ty...

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...

Abstract— Under CPA and CCA1 attacks, a secure bit encryption scheme can be applied bit-by-bit to construct a secure many-bit encryption scheme. The same construction fails, howe...
