Certificate-based cryptography combines the best aspects of identity-based encryption (implicit certification management) and public key encryption (no key escrow). To provide the ability of broadcast communication and leakage resilience for the certificate-based key encapsulation mechanism
a new cryptographic primitive
called leakage-resilient key encapsulation mechanism with anonymity and multi-receiver
is proposed in this paper; the formal definition and the leakage-resilient security model of our proposal are also described. The concrete construction of the above cryptographic primitive is created
and the corresponding leakage-resilient chosen-plaintext attacks security is proved based on the hardness of the decisional Diffie-Hellman assumption. The corresponding analysis shows that our scheme has better performance in anonymity
leakage resilience
and multi-receiver and so on; also
better computational efficiency can be achieved when generating encapsulation keys for multiple users.
