METHODS AND SYSTEMS FOR RANDOMIZED MESSAGE GENERATION FOR CRYPTOGRAPHIC HASH FUNCTIONS

摘要

Methods and systems for generation of randomized messages for cryptographic hash functions are described herein. The method includes obtaining a random value in a binary bit form for randomizing a message. The method also includes splitting the message into multiple message blocks, where a length of each of the multiple message blocks is based on a length of the random value and a block length of a compression function. The method further includes prepending and appending each of the multiple message blocks with at least a portion of the random value and concatenating the prepended and appended message blocks to obtain a message envelope for generating the randomized message.

1. A method for generating a randomized message for a cryptographic hash function, the method being implemented by a processor, the method comprising:
obtaining a random value in a binary bit form for randomizing a message; splitting the message into multiple message blocks, wherein a length of each of the multiple message blocks is based on a length of the random value and a block length of a compression function; prepending and appending each of the multiple message blocks with at least a portion of the random value; and concatenating the prepended and appended message blocks to obtain a message envelope for generating the randomized message.
