Embodiment Construction
[0030] Aiming at the problems existing in the prior art, the present invention proposes a SM2 algorithm-based signature scheme and decryption scheme suitable for cloud computing environments. The SM2 algorithm is a standard commercial cryptographic algorithm, which is widely supported and used in cryptographic products.
[0031] In order to make the technical solution of the present invention more clear and understandable, the solution of the present invention will be further described in detail below with reference to the accompanying drawings and examples.
[0032] figure 1 It is a flow chart of an embodiment of the SM2 algorithm-based signature method applicable to cloud computing in the present invention, such as figure 1 As shown, the following steps 11-14 are included.
[0033] Step 11: The first communication party generates its own sub-private key D1, and the second communication party generates its own sub-private key D2.
[0034] For the convenience of expression,...
