Embodiment Construction
[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.
[0026] figure 1 It is a schematic flowchart of a secure access method provided by an embodiment of the present invention. The secure access method provided in this embodiment is applicable to the situation where the secure access server verifies the received access request data. Specifically, it can be used to match the digital signature with the candidate digital signature in the pre-stored Let the attack situation. Specifically, the method may be executed by a security access device, the device may be implemen...

An embodiment of the invention discloses a security access method and device, equipment and a storage medium. The security access method comprises the following steps of: determining an access type according to access request data; if the access type is a preset access type, determining whether a digital signature in the access request data is consistent with a candidate digital signature in a pre-stored database or not; and if so, determining that the access request is illegal access. According to the security access method of the invention, the access type is determined, therefore, whether the access request is an important access except query or not is accurately judged, and under the condition that the access request is an important access, whether the access request is a replay attackor not is accurately determined through matching of the digital signature and the candidate digital signature in the pre-stored database, so that the access security is ensured.
Description
technical field [0001] The embodiments of the present application relate to the technical field of communication security, and in particular, to a secure access method, device, device, and storage medium. Background technique [0002] With the continuous popularization of Internet technology, various organizations can deploy various types of information systems, which brings great convenience to our work and life. But at the same time, network attackers are everywhere. They can detect loopholes in system access, and use these loopholes to achieve illegal access, illegal operations, and even damage the system. For example, replay attack: the intruder X intercepts the message sent by A to B by some means, and then X sends the intercepted message to B as it is, making B mistakenly think that X is A, so as to deceive the system. It is mainly used in the identity authentication process and destroys the correctness of authentication. It may also be a request hijacking attack: th...
