  • Method for preventing and detecting hash collisions of data during the data transmission
    Patent number: 8086860
    Abstract: A means for avoiding hash collisions by means of message pre-processing function to increase randomness and reduce redundancy of an input message whereby hash collisions are avoided when it is applied before hashing any message and the message pre-processing function comprises 4 steps like shuffling of bits, compression T-function and LFSR which steps increase the entropy of the input message at the end of 4 rounds, the output becomes more random.
    Type: Grant
