Problems solved by technology

[0004] In the prior art, when the user node communicates with the small ISP node, there needs to be a session key between the user node and the small ISP node. If the large ISP node or other intermediate nodes maliciously forge the public key of the small ISP node, the The forged public key is sent to the user node, and when the user node encrypts the session key with the public key, the encrypted session key will be cracked, resulting in low communication security between the small ISP node and the user node

Embodiment Construction

[0029] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0030] The session key transmission method provided by the embodiment of the present invention can be applied to figure 1 The communication system shown. Such as figure 1 As shown, the communication system includes: Internet service provider node 1-Internet service provider node 5, and user nodes, wherein, Internet service provider node 1 can be a small ISP node, Internet service pro...

Abstract

The embodiment of the invention provides a session key transmission method and device and a computer readable storage medium. The method comprises: a user node receiving a block in a block chain sentby a first ISP node; the user node obtaining a public key of the first ISP node from the block, encrypting the session key by using the public key of the first ISP node to obtain encrypted information; sending the encrypted information to the first ISP node. Therefore, the user node and the small ISP node can obtain the same session key, and the session key is adopted in the subsequent communication process. Due to the fact that the block cannot be forged, or even if a large ISP node or other intermediate nodes maliciously forge the block, a long time is needed, and the forging process is veryeasy to perceive, the security of the public key of the first ISP node is improved, and the security of communication between the first ISP node and the user node is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular, to a session key transmission method, device, and computer-readable storage medium. Background technique [0002] With the development of smart terminals, users can install various application programs (Application, APP) on smart terminals, and different APPs can provide users with different services. [0003] However, when a user installs an APP on a smart terminal, the user needs to register on the corresponding Internet Service Provider (Internet Service Provider, ISP) server of the APP. Register on the ISP server. As the number of APPs installed by users on smart terminals continues to increase, if users register the same user names and passwords on different ISP servers, it is easy to cause user names and passwords to be leaked. If the user names and passwords registered by users on different ISP servers are different, it will be difficul...
