On a Variation of Kurosawa-Desmedt Encryption Scheme.
Le Trieu Phong, Wakaha Ogata · 2006
Kurosawa-Desmedt encryption scheme is a variation of CramerShoup encryption schemes, which are the first practical schemes secure against adaptive chosen ciphertext attack in standard model. We introduce a variant of Kurosawa-Desmedt encryption scheme, which is not only secure against adaptive chosen ciphertext attack but also slightly more e#cient than the original version.
