Embodiment Construction
[0068] The present invention will be further described below in conjunction with the accompanying drawings.
[0069] The system combines the public key infrastructure PKI with the elliptic curve encryption mechanism to realize the certificate application, certificate issuance, certificate acquisition, widget signature and widget verification of mobile widget developers. On this basis, by improving the traditional scalar multiplication operation in the elliptic curve algorithm, the speed of widget signature and verification is accelerated. The overall structure of the system is as figure 1 Shown:
[0070] The whole system is divided into three modules, the developer module, the certification body module, and the client module.
[0071] The overall process of the system is as follows:
[0072] 1) Generate a certificate
[0073] Developers need to first submit a developer certificate application to the registration authority RA, and RA will review the relevant content and dec...
