Cryptographic Algorithms Analyzing of Different Combination with Secret and Public Key using Text and Audio Files: A Review

Secure messages and key management have been a focal point in cryptography. In the cryptographic systems, the notion of key is referred an numerical value which is used by an algorithm, making the information secure and visible only to individuals that possess the proper key to discover that information. In this article we will explain the concepts of private key and public key cryptography, and combined cryptography in terms of protecting information that is being sent through Internet. Further, we will analyze some secret and public algorithms, and combined algorithms with LABView. The speed measurement of these algorithms also represents a significant contribution. This work will focus primarily on the encryption and decryption of real time. This proposed paper focuses on implementing a secure using text and audio files technique that enables to select one of the several using text and audio files displayed simultaneously with a unique security key for each using IMAQ toolbox of LABView.
