A New Approach towards Encryption Technique: D?s Crypto-Cipher Technique (DCCT)

摘要

Information Security is a major challenging issue in today’s technological world. There is a huge demand for a stronger and secure encryption techniques which are very hard to crack. Earlier so many researcher have proposed various encryption techniques and algorithm such as DES, AES, Blowfish, RSA, Feistel block cipher etc. Some of them are very popular in achieving data security at a great extent like Blowfish and AES. But nowadays as security level is increased the time span and complexity of algorithm to perform various operations is also increased. This is the major cause of decreasing efficiency and speed of an encryption techniques. For this we have proposed a new encryption technique named “D’s crypto-cipher technique (DCCT)” with a random key generation which enhance security level as well as speed and efficiency of an encryption system. The (DCCT) is applied on a plaintext block with a random key generation where the key is also encrypted at another location rather than original location. In this abstract we have proposed a new invented encryption technique which is very secure and very efficient. (DCCT) is implemented in a way like ‘Hide and Seek.’ But to seek by cryptanalyst is very hard and may be not possible.
