Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0042] In the following embodiments of the present application, the execution entity of the method may be an authentication server, which serves as an intermediate scheduling platform.

[0043] Figure 1 FIG. 1 is a flow chart of an authentication method for requesting in a heterogeneous network according to an embodiment of the present application; Figure 1 As shown, it includes:

[0044] S101, obtaining an identity registration request in a heterogeneous network, and mapping the received identity registration request to a shared authentication interface;

[0045] Optionally, in this embodiment, an identity registration request in a heterogeneous network is obtained, and the received identity registration request is subjected to a convolution-like processing to be mapped to a shared authentication interface, including: obtaining an identity registration request in a heterogeneous network, and performing a convolution-like processing on the received identity registration request to be mapped to a shared authentication interface.

[0046] In this embodiment, when performing the quasi-convolution processing, each data component in the identity registration request is extracted and converted into a matrix vector, and the quasi-convolution processing is performed with the set core matrix, so as to achieve mapping to the shared authentication interface.

[0047] In this embodiment, the size of the set core matrix is ​​adapted to the dimensions of each data component in the identity registration request.

[0048] Of course, in some embodiments, the specific element values ​​in the core matrix are flexibly set according to demand, or are adaptively adjusted as the application scenario is used.

[0049] Optionally, in this embodiment, after obtaining the identity registration request in the heterogeneous network, it includes: parsing the identity registration request to obtain a timestamp, and adding the identity registration request to an identity authentication time sequence based on the timestamp.

[0050] In this embodiment, based on the identity authentication time sequence, the identity registration request can be effectively managed according to the timestamp, thereby avoiding data conflicts in the data processing process. When the identity registration request is to be used later, the identity authentication time sequence can be directly inquired.

[0051] Optionally, in this embodiment, parsing the identity registration request to obtain a timestamp, and adding the identity registration request to an identity authentication time sequence based on the timestamp, includes: parsing the identity registration request to obtain a timestamp, and generating an authorization authentication statement based on the timestamp to add the identity registration request to the identity authentication time sequence.

[0052] In this embodiment, there is no special limitation on the parsing method of the identity registration request, such as based on get or post method.

[0053] S102, performing structured processing on the identity registration request to obtain an object access request, and issuing the object access request;

[0054] In this embodiment, the structured processing of the identity registration request to obtain an object access request and issuing the object access request includes: adding a request validity period statement to the identity registration request to structure the request to obtain the object access request, and issuing the object access request. Structuring based on the request validity period statement is equivalent to realizing a secondary identification of the identity registration request, thereby improving the security of subsequent authentication.

[0055] Specifically, when structuring, for example, the identity registration request with the request validity period statement added is structured in XML to obtain an XML text stream, which is directly used as the object access request. Further, the object access request is published, for example, through a hyperlink or form.

[0056] S103: construct an identity authentication request message according to the object access request, wherein the identity authentication request message includes a message header and a message body;

[0057] The message header includes a request identifier of the identity registration request, the message body includes a request container, and the request container is used to store attribute data of the identity registration request;

[0058] In this embodiment, constructing an identity authentication request message according to the object access request includes: obtaining at least one of a credit rating, a historical legitimacy statement, and a heterogeneous access permission description of a user who initiates the access request, and adding it to the request container.

[0059] Specifically, in this embodiment, the attribute data of the identity registration request includes at least one of the user's credit rating, historical legitimacy statement, and heterogeneous access rights statement. Specifically, the credit rating, historical legitimacy statement, and heterogeneous access rights statement are equivalent to strengthening security.

[0060] S104: Map the identity authentication request message to a shared authentication component to authenticate the identity authentication request message.

[0061] Optionally, in this embodiment, mapping the identity authentication request message to a shared authentication component to authenticate the identity authentication request message includes: obtaining a shared token, adding the token to the identity authentication request message to map it to the shared authentication component to authenticate the identity authentication request message.

[0062] Optionally, in this embodiment, mapping the identity authentication request message to a shared authentication component to authenticate the identity authentication request message includes: obtaining shared credentials, adding the credentials to the identity authentication request message to map to the shared authentication component to authenticate the identity authentication request message.

[0063] In this embodiment, the token or the credential may be generated by a network node with the highest credibility in the heterogeneous network.

[0064] Specifically, mapping to a shared authentication component is performed, such as mapping through a built HTTP service.

[0065] Optionally, mapping the identity authentication request message to a shared authentication component to authenticate the identity authentication request message includes: mapping the identity authentication request message to an authentication component shared locally on a unified authentication server to authenticate the identity authentication request message.

[0066] In this embodiment, all identity authentication request messages are specifically shared by the authentication component locally on the unified authentication server, thereby ensuring that all identity authentication request messages can have a unified interactive interface standard, improving the channel specificity of authentication in heterogeneous networks, and ensuring the security of the authentication process.

[0067] In this embodiment, the shared authentication component authenticates the identity authentication request message, including judging the timeliness of the request, the above-mentioned token, and the matching of the above-mentioned credentials. When it meets the preset matching criteria, it can be determined to be legal, otherwise it is determined to be illegal.
