摘要：
Certificate-based cryptography combines the best aspects of identity-based encryption (implicit certifica⁃ tion management) and public key encryption (no key escrow). To provide the ability of broadcast communication and leak⁃ age 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 hard⁃ ness of the decisional Diffie-Hellman assumption. The corresponding analysis shows that our scheme has better perfor⁃ mance in anonymity, leakage resilience, and multi-receiver and so on; also, better computational efficiency can be achieved when generating encapsulation keys for multiple users. © 2023 Chinese Institute of Electronics.
