摘要：In this technical paper a session based symmetric key cryptographic technique, termed as SBSKCT, has been proposed. This proposed technique is very secure and suitable for encryption of large files of any type. SBSKCT considers the plain text as a string with finite no. of binary bits. This input binary string is broken down into blocks of various sizes (of 2k order where k = 3, 4, 5, ….). The encrypted binary string is formed by shifting the bit position of each block by a certain values for a certain number of times and from this string cipher text is formed. Combination of values of block length, no. of blocks and no. of iterations generates the session based key for SBSKCT. For decryption the cipher text is considered as binary string. Using the session key information, this binary string is broken down into blocks. The decrypted binary string is formed by shifting the bit position of each block by a certain values for a certain number of times and from this string plain text is reformed. A comparison of SBSKCT with existing and industrially accepted TDES and AES has been done.
