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 propose a practical public-key encryption scheme whose security against chosen-ciphertext attacks can be reduced in the standard model to the assumption that factoring is intrac...
Binary tree encryption (BTE), a relaxation of hierarchical identity-based encryption (HIBE), has recently emerged as a useful and intriguing primitive. On the one hand, the defini...
This paper proposes the first inner product encryption (IPE) scheme that is adaptively secure and fully attribute-hiding (attribute-hiding in the sense of the definition by Katz...
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...
