Design and Implement Dynamic Key Generation to Enhance DES Algorithm
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 7
Abstract
Cryptography is the process of transforming message to avoid an unauthorized access of data. Key is an important part in cryptography. For higher level of secure communication key plays an important role. For increasing the level of security in any communication this project proposed a Dynamic key generation unit. Dynamic key generation enhances the DES algorithm securities. As per the research done DES algorithm is weak due to its weak key generation, so that key generation can be reconfigured. Therefore to make key generation more effective and strong dynamic key generation unit is proposed here which is totally independent on DES algorithm. The system proposed here three ways to make key generation more stronger are user generated key, second one by using LFSR which is good key stream generator, third is by using chaotic encryption and fourth is 2’s complement. This system also has good resistance against brute-force attack which makes system more effective. Another part is DES algorithm and control unit is also designed for controlling the round of DES for encryption and decryption.
