Mahabir Prasad Jhanwar, Rana Barua · 2008
Abstract. We present a public-key encryption scheme which is provably secure against adaptive chosen ciphertext attack. The scheme is constructed using Cramer-Shoup paradigm [7]. The security of the scheme is based on the Decisional Bilinear Diffie-Hellman problem. Keywords: IND-CCA2(adaptive chosen ciphertext security), public-key encryption, DDH- Assumption,
