Abstract：
The invention provides encryption and decryption methods suitable for a high-speed data transmission path, and relates to the technical field of encryption and decryption. The encryption method comprises the steps that a binary random number is generated to serve as an auxiliary key, wherein the number of bits of the auxiliary key is preset; a round key library is obtained; based on the number ofthe bits of the auxiliary key, a plurality of round keys are extracted from the round key library, wherein the number of the extracted round keys is the same as the number of the bits of the auxiliarykey; and to-be-encrypted data in the data path is obtained, and is encrypted by sequentially utilizing the extracted round keys.
