On Some Variations of Kurosawa-Desmedt Public-Key Encryption Scheme
Le Trieu Phong, Wakaha Ogata · IEICE Transactions on Fundamentals of Electronics Communications and Computer Sciences · 2007
Kurosawa-Desmedt public-key encryption scheme is a variation of Cramer-Shoup public-key encryption schemes, which are the first practical schemes secure against adaptive chosen ciphertext attack (IND-CCA) in standard model. We introduce some variants of Kurosawa-Desmedt public-key encryption scheme which are also IND-CCA secure. Furthermore, the variants are either more efficient or less cryptographic assumptions than the original version.
