Abstract

This paper focuses on the analysis of the two types of key cryptography which exist, based on the availability of the key publicly: private key cryptography, and public key cryptography. Both the sender and the recipient share a key that must be kept private. In the former case, the sender and recipient share a private key between the two of them which must be distributed first before actual communications take place. This analysis shows how very complicated and difficult this is to do properly. The most famous example of this type of cryptography is the data encryption standard (DES). In public key cryptography, each party has two sets of keys; one key is known to the public while the other is kept secret to the owner.
