Example Embodiment

[0030] In view of the problems in the prior art, the present invention proposes a signature scheme and a decryption scheme based on the SM2 algorithm that are suitable for cloud computing environments. SM2 algorithm is a standard commercial cryptographic algorithm, which is widely supported and used in cryptographic products.

[0031] In order to make the technical scheme of the present invention clearer and more comprehensible, the scheme of the present invention will be further described in detail below with reference to the drawings and embodiments.

[0032] figure 1 It is a flowchart of an embodiment of a signature method based on the SM2 algorithm suitable for cloud computing in the present invention, such as figure 1 As shown, the following steps 11-14 are included.

[0033] Step 11: The first communicating party generates its own child private key D1, and the second communicating party generates its own child private key D2.

[0034] For ease of presentation, the first communic...

Abstract

The invention discloses a signing and decrypting method and system applied to cloud computing and based on an SM2 algorithm. Specifically, two communicating parties store some private keys respectively, operation of signing, decrypting and the like can be carried out on information only when the two parties unite, the two communicating parties can not obtain any information about the private key of the opposite side, and therefore under the circumstance that an attacker invades any party, signatures can not be forged, or ciphertexts can not be decrypted, so that the safety of the private keys in the cloud computing environment is improved; moreover, in the signing and decrypting processes, the application requirements for low delay and less interaction in the cloud computing environment can be met with less interaction needing to be carried out between the two communicating parties.

Description

technical field [0001] The invention relates to the field of encryption, in particular to a SM2 algorithm-based signature and decryption method and system suitable for cloud computing. Background technique [0002] At present, digital signature and encryption and decryption technologies based on public key cryptography have been widely used in e-commerce, identity authentication and other applications, and have become an important tool to ensure information security, and the security and use of private keys are the basis for ensuring the security of these applications . [0003] In the cloud computing environment, the main resources are gathered on the server side, and the client side usually exists in the form of weak terminals, such as smart phones, etc. Such weak terminals usually store and use private keys in the form of software, so the security protection capability is poor . For example, if the private key is completely stored in a single file on the smartphone, the...
