Embodiment Construction

[0071] The embodiment of the present invention provides a method for dynamically updating the signature algorithm. When a service terminal requests a service from the service integration platform, it first checks whether the local signature algorithm is invalid, and if so, synchronizes with other service terminals in the LAN through a multicast channel. Signature algorithm, if the synchronized signature algorithm is still invalid, obtain a new signature algorithm from the service integration platform, and refresh the local signature algorithm with the obtained new signature algorithm.

[0072] Such as figure 2 As shown, a method for updating a signature algorithm provided by an embodiment of the present invention, the specific steps include:

[0073] Step 201, before the service user terminal (i.e. ISV application) sends a service request to the service integration platform, it first compares the validity period of the local signature algorithm with the local time to verify w...

Abstract

The invention discloses a method for updating a signature algorithm and a system thereof. The method for updating the signature algorithm is as follows: when ISV application sends a service request, a period of validity in the signature algorithm is used for checking whether the local signature algorithm is invalid, if yes, the signature algorithms of other network nodes are synchronized by a multicast channel in a local area network, if the synchronized signature algorithm is still invalid, a request for updating the signature algorithm is sent to a service integration platform to obtain a new signature algorithm. The invention uses two methods (the synchronized signature algorithm and the updating signature algorithm by the interaction between the ISV application and the service integration platform) in the local area network to realize updating of the signature algorithm, which enhances the safety of the signature verification.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to a method and system for updating a signature algorithm. Background technique [0002] The service-oriented architecture (Service-Oriented Architecture, SOA) continues to mature, and the representational state transfer (REST) ​​style is deeply rooted in the hearts of the people, making Internet open services gradually become a new Internet resource. Traditional Internet software companies have also begun to try new roles, as service providers, open their own service resources, and provide a new open model for the development of the website itself. At the same time, the enrichment of Web applications has also created many independent software vendors (ISVs, Independent Software Vendors). These independent software vendors use the effective service resources of the network to design a variety of interactive applications ( ISV applications, that is, service use terminals), ...
