Efficient Certificateless KEM in the Standard Model

Abstract. We give a direct construction of a certificateless key encapsulation mechanism (KEM) in the standard model that is more efficient than the generic constructions proposed before by Huang and Wong [10]. We use a direct construction from Kiltz and Galindo's KEM scheme [11] to obtain a certificateless KEM in the standard model; our construction is roughly twice as efficient as the generic construction. We also address the security flaw discovered by Selvi et al. [16].
