Problems solved by technology

[0011] During the application and implementation of CPK, the user needs to deploy the CPK key management system, and deploy different versions of the key management system according to different business requirements. The key management system is deployed in the form of a hardware server. During the formal implementation process, the user The key is downloaded and stored in the U-key, which increases the hardware cost for the user, and the U-key may be lost during use, causing troubles for the user

Embodiment 1

[0042] [Embodiment 1] Customer Zhang San pays customer Li Si online.

[0043] Such as figure 1 As shown, the payer Zhang San wants to pay the payee Li Si online, and both use the mobile phone e-wallet client to operate. The soft key system is installed on the Zhang San mobile phone, Li Si mobile phone, and the background management system. run. Li Si enters the amount on the mobile phone, and the e-wallet client generates a QR code with the payee information and payment information.

[0044] Zhang San scans the QR code, and the soft key system in Zhang San’s mobile phone selects a random number R, uses Zhang San’s private key to sign the random number R, and signs the recipient information, payment information, payer information, and signature The information is sent to the background management system together.

[0045] After the background management system receives the above information, the soft key system verifies the signature information: that is, the public key is mapped ou...

Embodiment 2

[0046] [Embodiment 2] Customer Zhang San pays customer Li Si offline.

[0047] Such as figure 2 As shown, the payer Zhang San wants to pay the payee Li Si offline, and both use the mobile phone electronic wallet client to operate, and the soft key system is installed and running on both Zhang San mobile phone and Li Si mobile phone. Li Si enters the amount on the mobile phone, the soft key system selects a random number R, uses the private key to sign the random number R, and generates a QR code with transaction information, Li Si ID information, and signature information.

[0048] Zhang San scans the QR code, the soft key system uses the Li Si ID and the business subdomain ID to map out the public key, and uses the public key to verify the signature information of Li Si. If the verification fails, the process ends.

[0049] If the verification is successful, Zhang San’s mobile client asks whether he agrees to the payment operation. If Zhang San refuses, the process ends. If Zhang...

Abstract

The invention discloses a novel terminal safety soft secret key management method. According to the method, information of two transaction parties are selected by a soft secret key system as identification ID, public and private key pairs are formed through mapping on the basis of business subdomain identification; for online payment, a two-dimensional code is generated at a receiving party; after the two-dimensional code is scanned by a payment party, signature is carried out by utilizing a private key pair randomized number, and information is sent to a background management system; signature verification is realized by the background management system through utilizing public key pair signature information; if signature verification succeeds, transaction is processed; for offline payment, signature is carried out by the receiving party through utilizing the private key pair randomized number, and a two-dimensional code is generated; the two-dimensional code is scanned by the payment party, and signature verification is realized through public key pair signature information; if signature verification succeeds, payment is carried out by the payment party according to transaction information; signature is carried out by the payment party through utilizing the private key pair randomized number, a two-dimensional code is generated; the two-dimensional code is scanned by the receiving party, and signature verification is realized through public key pair signature information; if signature verification succeeds, payment is successfully realized for the receiving party. Through the method, system safety is not only improved, system disposition cost is further reduced, transaction validness is fully guaranteed, and invalid information tampering and information steganography can be avoided.
