In this module, the concepts of public-key encryption are introduced. You will learn about the origins of public-key cryptography and its underlying architecture and syntax. The various schemes that are based on the public key cryptosystem will also be analyzed.

In this module, learn about chosen-ciphertext-security for public-key cryptosystems. Public key ciphers— which are based on various security models— will also be discussed.

In this module, you will be introduced to the various identification schemes and their properties. You will also learn about the concept of zero-knowledge protocols and their applications.
