The cryptosystem recently proposed by Cramer and Shoup [CS98] is a practical public key cryptosystem that is secure against adaptive chosen ciphertext attack provided the Decision...
Recently Cash, Kiltz, and Shoup [20] showed a variant of the Cramer-Shoup (CS) public key encryption (PKE) scheme [21] whose chosen-ciphertext (CCA) security relies on the computa...
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...
