Abstract

In an intrusion-resilient cryptosystcm [10], two entities (a user and a base) jointly evolve a secret decryption key; this provides very strong protection against an active attacker who can break into the user and base repeatedly and even simultaneously. Recently, a construction of an intrusion-resilient public-key encryption scheme based on specific algebraic assumptions has been shown [6]. We generalize this previous work and present a more generic construction for intrusion-resilient public-key encryption from any forward-secure public-key encryption scheme satisfying a certain homomorphic property.
