In this paper we examine the security criteria for a KEM and a DEM that are sufficient for the overall hybrid encryption scheme to be plaintext-aware in the standard model. We appl...

We present a new encryption scheme which is secure against adaptive chosenciphertext attack (or CCA2-secure) in the standard model (i.e. without the use of random oracle). Our sch...

Abstract. Recently, Bellare and Palacio succeeded in defining the plaintext awareness, which is also called PA2, in the standard model. They propose three valiants of the standard ...
