Problems solved by technology

Installing such an application on the card may bring many uncertain security risks to the smart card
[0009] (2) Application integrity cannot be guaranteed
Installing such an application on the card may cause the installation to fail, or cause the risk of user information being illegally stolen by criminals.
[0011] (3) Application authorization installation cannot be guaranteed
Once the authorized application installation files are copied to other unauthorized large-capacity cards, it is possible that unauthorized users can successfully install applications, which will cause great damage to the interests of application providers

Abstract

The invention discloses a method and a system for realizing smart card application and deployment, wherein the method comprises that application installation documents and checking documents are packed as an application installation document wrap to be published when application is published. When the application is installed, if the application installation document wrap is checked out without a checking document wrap, or the calculated abstract value is not consistent with the abstract value of the checking data plaintext decrypted from the checking documents, or users which need to be authorized are unauthorized, the application installation must be prohibited, otherwise, the installation is allowed. The method and the system have the advantages of guaranteeing the legitimate interests of application suppliers effectively, prohibiting installation of all the incomplete or tampered application by means of checking the completeness of the application, and supporting the authorized application installation, so that the legitimate interests of the installation suppliers and the authorized users are guaranteed in the meanwhile.

Description

technical field [0001] The invention relates to smart card technology, in particular to a method and system for implementing smart card application deployment. Background technique [0002] Java Card is a smart card that can run java programs. It has become the mainstream application of smart card technology in the Internet age due to its support for multiple applications, good security features, object-oriented programming environment, and dynamic download of applications. Java Card smart card products have been widely used all over the world, including wireless communication, medical / health insurance, financial banks, government agencies, military, identity authentication, e-commerce and system security. Among them, the large-capacity SIM (or USIM) card used in the field of wireless communication is a kind of smart card. In addition to the flash used by ordinary smart cards, the large-capacity card also has built-in high-density, low-power, low-cost and upgradeable The na...
