AbstractMost threshold key encapsulation mechanisms (KEM) have been studied in a weak model–static corruption model or random oracle model. In this paper, we propose a threshold KEM scheme with provable security based on the bilinear groups of composite order in the standard model. We use a direct construction from Boyen-Mei-Waters’ KEM scheme to obtain a threshold KEM scheme that can withstand adaptive chosen ciphertext attacks (CCA) and adaptive corruption attacks. However, to achieve a higher security level, our construction does not increase overall additional size of ciphertext compare to other schemes.

Index TermsKey encapsulation mechanisms; Adaptive corruption attacks; Chosen ciphertext attack; Bilinear groups of composite order.
