【 摘 要 】

A revocable identity-based encryption (IBE) scheme under learning with error (LWE) assumption from lattice is proposed; compared with the existing IBE schemes from lattices, two improvements are available in the new scheme. First, the revocation mechanism for identity of user (or thing) is added in the new scheme to manage the dynamic user (or thing) identity in the system, and making the IBE scheme from lattice becomes more practical than ever before. Second, the security of the new scheme is based on the LWE assumption from lattice, so our construction has a solid secure foundation. The scheme is proved to be secured against adaptive-ID attacks under LWE assumption from lattice in the standard model.
