Abstract :
A modification of the public-key cryptosystem proposed by Okamoto is presented. This modification appears to be resistant to Shamir´s cryptanalytic attacks on the original cryptosystem. In addition, a variant whose data expansion rate due to encryption is less than that of the modification is also proposed.
