Embodiment Construction

[0035] Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0036] FIG. 3 is a block diagram illustrating the structure of a class library footprint file 300 for authenticating a JAVA application according to an exemplary embodiment of the present invention. All JAVA applications have a class library footprint file, which includes authentication information for verifying the integrity of all class libraries used by the JAVA application before executing the JAVA application.

[0037] Referring to FIG. 3 , the class library footprint file 300 includes a list of class libraries and a summary value 304 of the class libraries. The class library footprint file 300 may include signature information 302 for verifying the integrity of the class library footprint file 300 .

[0038] FIG. 4 is a partial computer code of a class library footprint file according to an exemplary embodiment of the present inve...

Abstract

A class library footprint file for authenticating a dynamically loaded class library during the execution of a JAVA application and a JAVA application authentication method using the class library footprint file are provided. The class library footprint file includes: authentication information for verifying the integrity of one or more class libraries used by the JAVA application before the JAVA application is executed. A list of class libraries to be authenticated is provided, in advance, to a JAVA application.

Description

technical field [0001] The present invention relates to the authentication of JAVA application, more specifically, relate to a kind of class library footprint (footprint) file that is used for authenticating the class library of dynamic loading during the execution of JAVA application, and use described class library footprint file JAVA application authentication method. Background technique [0002] In the field of broadcasting or storage, content providers widely use JAVA applications to provide various interactive services to users. Various JAVA application authentication methods have been proposed to allow users to safely execute JAVA applications provided by content providers. [0003] Content providers or hosts distribute signed JAVA applications to users according to specific delivery algorithms. A traditional JAVA application authentication method includes: using a JAVAmanifest file including a digest (digest) value list, a signature file of the JAVA manifest file,...
