The concept of stateful encryption was introduced by Bellare et al. in 2006. Compared with conventional public key encryption scheme, stateful encryption can achieve much better encryption performance. In this paper, we introduce a related primitive called stateful identity based key encapsulation mechanism (SIBKEM). SIBKEM is a simpler primitive, however, together with multi-time use IND-CCA secure symmetric encryption, it implies secure stateful identity based encryption. We then demonstrate there is a generic construction of SIBKEM from a wide class of identity based non-interactive key exchange schemes. © 2009 Springer Berlin Heidelberg.
