Problems solved by technology

Mobile Widget packages lacking digital signatures may be modified without authorization, and end users cannot know that the source of the mobile Widget is a reliable source they trust, which may lead to user information leakage or other security issues

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...

Abstract

The invention provides a digital signature authentication method facing a mobile widget, which comprises the following steps that: a certificate is generated; a developer submits a developer certificate application to a registration authority RA in a certification authority, the RA audits related contents and determines whether to examine and approve a request of the certificate application, the RA submits the application request and information that the approval is passed to a certificate authority CA after the certificate application passes the approval, and the CA signs and issues the certificate; the signature is carried out; after the certificate application is approved to register, an application program at the RA end initializes information of an applicant, issues the certificate to the developer, sends a privacy key, the CA adds related information of the certificate applicant in a LDAP (Lightweight Directory Access Protocol) directory server, the developer signs a program passing compilation on a development platform after receiving the privacy key and uploads the signed program to a Web server; and the verification is carried out. The invention combines a public key infrastructure PKI and an oval curve encryption mechanism and implements the certificate application, the certificate issuing, the certificate acquisition, the widget signature and the widget verification of the mobile widget developer are implemented.

Description

technical field [0001] The invention relates to the field of mobile Internet security, in particular to a digital signature authentication method of a mobile Widget. Background technique [0002] The Widget business originates from a platform that can add Java Script applets first developed on Apple’s Mac OS X operating system in 2003. The applets on this platform were later gradually expanded to feature desktops and the Internet. A variety of richer applications. Since the development of Widgets has obvious Internet characteristics, W3C documents also refer to Widgets as Client-Side Web Applications. W3C organization defines Internet Widgets (Web Widgets): Widgets are A class of client applications that can display and update local data or web data, and can be packaged into a single download package and installed on the client device. The W3C definition of widgets highlights client-side applications, capable of displaying and updating data, capable of being packaged into ...
