Analysis and performance evaluation of cryptographic algorithms for secure two party communications
Mohammed Firdos Alam Sheikh, Santosh Kumar Sharma · 2017
Security techniques have more than a particular algorithm or protocol for encryption & decryption purpose and as well as for generation of sub keys to be mapped to plain text to generate cipher text. There is no single mechanism that will provide all the services specified. But we can identify a very important mechanism that supports all forms of information integrity is cryptographic technique. Encryption of information is the most common means of providing security. In this work an attempt has been made to generate two algorithms which provide security to data transmitted. The first algorithm considers a random matrix key which on execution by a series of steps generates a sequence. This sequence is used a sub key to build three different encryption models. Each model can be used for encryption of data. The second algorithm considers not only the key but also initialization vector and a time stamp to generate sub keys which are used for encryption process. And also a mechanism has been discussed which identifies any garbled key while transmitted from the Key Distribution Centre.
