RSA, Public-Key Cryptography, and Authentication Protocols

Abstract

In the modern electronic age, secure communication is vital to the efficient workings in all areas of life. From governmental proceedings and military devices to personal banking and email, securely communicating between parties has become a necessity that has furthered research in the field of cryptography. This thesis is an introduction to a particular type of cryptography, public-key cryptography, and examines the basics of RSA and ElGamal cryptosystems. Worked-out examples for these types of encryption, decryption and authentication protocols are explored, as well.
