Breaking RSA OAEP with Manger Attack
The RSA cryptosystem has had its fair share of attacks over the years, but among the most impressive, you can find the infamous Bleichenbacher attack [Ble98], which doomed PKCS v1.5 in 1998. Nineteen years later, the ROBOT attack proved that the Bleichenbacher attack was still a concern today. Now, what alternatives to RSA PKCS v1.5 do we have?
Well, itssuccessor, RSA OAEP also known as RSA PKCS v2.1 is obviously a good candidate.
