Abstract :
Network safekeeping strategies initiation and execution is crucial for the purpose of secured data
transmission and confidentiality. Cryptography is a technique which is developed solely for the purpose of data
security and integrity in the process of communication. Though several theories and concepts exists, each varies with
the amount of security it offers to the network channel. An important element which determines the type of
cryptography is key distribution. Based on the type of key distribution, cryptography is broadly classified as
symmetric and asymmetric. In this paper, the classical algorithms which are used for symmetric and asymmetric
cryptography are analysed in terms of their pros and cons in various aspects.
