WebLattice-based forward secure PEKS scheme (FS-PEKS) overcomes the two problems above by combining the techniques of forward security and lattice-based cryptography. However, FS-PEKS schemes work in public key infrastructure (PKI), which will incur complicated certificate management procedures. WebIn the PEKS context, forward secure PEKS (FS-PEKS) is essentially the same as public key encryption with temporary keyword search (PETKS) proposed by Abdalla et al. (JoC 2016) which can be constructed generically from hierarchical identity-based encryption (HIBE) with level-1 anonymity. Alternatively, Zeng et al. (IEEE Transactions on Cloud ...

WebSep 1, 2024 · Public-key encryption with conjunctive keywords search (PECKS) is an extension of public-key encryption with keywords search (PEKS), which can realize the efficient search of the encrypted data stored in the cloud server and keep the privacy of these data during the search phase. WebFS-PEKS is constructed on a hierarchy identity-based encryption based on the hardness assumption of deciding LWE problem, and therefore is secure against quantum attacks. We de- ﬁne the ﬁrst formal security model of forward secure PEKS scheme, and present formal security proof of FS-PEKS under the proposed model.
