Abstract
Optimal Asymmetric Encryption Padding (OAEP) is a technique for converting the RSA trapdoor permutation into a chosen cipher-text secure system in the random oracle model. OAEP padding can be viewed as two rounds of a Feistel network. We show that for the Rabin and RSA trapdoor functions a much simpler padding scheme is sufficient for chosen ciphertext security in the random oracle model. We show that only one round of a Feistel network is sufficient. The proof of security uses the algebraic properties of the RSA and Rabin functions. © Springer-Verlag Berlin Heidelberg 2001.
