Summary
Most public key encryption algorithms base their security on number theoretic problems. Unlike to private key algorithms, were the key is selected from the user, in public key algorithms the key is constructed by the computer. In this construction, whether it is RSA, El Gamal or other algorithm, a central role belongs to the generation of big prime numbers. The talk will focus on the foundations of public key cryptography, something that is usually taken for granted the key generation procedure. Topics that are going to be discussed are how do we construct big prime numbers and public keys, what are the known methods, what are the properties that the keys should have. Moreover, we discuss the risks that the user/developer is exposed to (Secretly Embedded Trapdoor with Universal Protection schemes) and best policies.
