Abstract

To deal with the signing key exposure problem in fuzzy identity-based encryption systems with AND gates on attributes, we propose a fuzzy identity-based key-insulated encryption scheme with AND gates on attributes (FIBKIE-AGA). Our scheme is provably secure. Our scheme is (N-1,N)- key-insulated and strongly key-insulated. Even if temporary private keys for up to N-1 time periods are compromised, an adversary is still unable to derive this user’s temporary private key from the remaining time period. Even if the adversary exposes the secrets stored in the helper, there is still no security compromise.
