Embodiment Construction

[0053] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0054] The information processing method, device, and system of the embodiments of the present invention are described below with reference to the accompanying drawings.

[0055] In the prior art, the source node uses a pre-configured key pair for encryption and decryption. On the one hand, this method increases the load pressure on the source node. On the other hand, when the private key is leaked, the content of the message cannot be Keep it confidential. Therefore, the encryption method in the prior art is less effective.

Abstract

The invention provides an information processing method, device and system. The method comprises the following steps that a first-level server acquires a target message from a source node in a processof transmitting the target message, so that a control strategy is generated according to attribute information of a destination node; and attribute encryption is carried out on the target message according to the control strategy, so that the source node transmits the target encrypted message. Due to the fact that the first-level server is adopted to encrypt the target message, a process of nodeencryption is avoided, and the load of the node is reduced. Meanwhile, due to the fact that an attribute encryption mode is adopted, even if a private key is leaked, decryption can be carried out onlywhen the attribute information of the decrypted node conforms to a decryption condition, and the risk of leakage is reduced.

Description

technical field [0001] The present invention relates to the technical field of the Internet, in particular to an information processing method, device and system. Background technique [0002] A mobile social network is a social network established based on terminal mobility. In the mobile social network, the terminal used by the user is regarded as a node, and the nodes communicate with each other within a short distance to transfer information and achieve the purpose of information dissemination. [0003] In the process of transmitting a message from a source node to a destination node, since multiple intermediate nodes may be required to transmit the message, how to ensure the confidentiality of the message content during the transmission process has become an urgent problem to be solved. In the prior art, in order to ensure the confidentiality of the message, the source node encrypts the message based on a pre-configured key pair before starting message transmission. ...
