Abstract: The present invention provides a method for generating a seed and a device thereof. The method includes: obtaining an algorithm key and generating a target seed algorithm sequence by the algorithm key and a seed algorithm group; obtaining inputted seed generation data; and finally inputting the seed generation data into the target seed algorithm sequence to generate a seed corresponding to the seed generation data. A target seed algorithm is generated by a seed selection algorithm, the algorithm key, calculation rounds and a target seed algorithm group are inputted into the seed selection algorithm, and the target seed algorithm adopted in the current calculation round is outputted. The target seed algorithm for all calculation rounds is combined into a target seed algorithm sequence. This invention increases the computational complexity of the third party through the seed generation data to collide the seed, thereby improving the security of the seed.
