An Indian scientist has claimed to have developed the fastest internationally known method to encrypt hard disk of a computer so that data remains secure even from attack by hackers.
The new algorithm developed by Palash Sarkar, a professor at the Indian Statistical Institute (ISI), Kolkata, is reportedly 30 to 40 per cent faster than the previous ones.
From a practical point of view, the requirement is actually to achieve both speed and security. Otherwise, encryption and decryption may take so much time that software which run on computers become unacceptably slow, Sarkar said.
"And, in the current state of the art, this work provides the fastest known algorithm for disk encryption," Sarkar claimed.
The results of the research will appear in October 2009 issue of the 'IEEE Transactions on Information Theory´, one of the top research journals in the field of transmission, processing and utilization of information.
Asked how he claims his algorithm to be the 'fastest´, he replied, "One has to see this in the context of the anonymous and strict review process of the journal 'IEEE Transactions on Information Theory.´
The reviewers allowed this claim to stand because I could scientifically justify it in the paper. A hollow claim would have been struck down by the reviewers, he added.
