Abstract EN
There only exists one deterministic identity-based encryption (DIBE) scheme which is adaptively secure in the auxiliary-input setting, under the learning with errors (LWE) assumption.
However, the master public key consists of O(λ) basic matrices.
In this paper, we consider to construct adaptively secure DIBE schemes with more compact public parameters from the LWE problem.
(i) On the one hand, we gave a generic DIBE construction from lattice-based programmable hash functions with high min-entropy.
(ii) On the other hand, when instantiating our generic DIBE construction with four LPHFs with high min-entropy, we can get four adaptively secure DIBE schemes with more compact public parameters.
In one of our DIBE schemes, the master public key only consists of ω(logλ) basic matrices.
