CiteSeerX — RSA-OAEP is Secure under the RSA Assumption

Webtight security for RSA-OAEP under the RSA assumption. We als o show that security does not degrade as the number of ciphertexts an adversary can see increases. Moreover, OAEP can be used to encrypt long messages without using hybrid encryption. W e believe that this modiﬁcation is easy to implement, and the WebTherefore, this uses a formally stronger assumption. Nevertheless, since partial-domain one-wayness of the RSA function is equivalent to its (full-domain) one-wayness, it follows that the security of RSA–OAEP can actually be proven under the sole RSA assumption, although the reduction is not tight. 1 the 3rd street flats in mcminnville oregon

Conclusion: we consider RSA+OAEP secure because OAEP provides a security reduction to the RSA problem under CPA and CCA, and it helps mitigate implementation …
