In this paper, we propose a new identity-based parallel key-insulated encryption (IBPKIE) scheme which achieves IND-ID-KI-CCA2 security without random oracles.
To deal with the key-exposure problem in IBE settings, we further propose an identity-based threshold key-insulated encryption (IBTKIE) scheme. The proposed ...
In this paper we apply the key-insulation mechanism to minimize the damage of key-exposure in IBS schemes. We propose a concrete key-insulated ID-based ...
