Abstract
The invention discloses an instant messaging method and system capable of guaranteeing safety of the user communication content. Encryption, decryption and transmission of the communication content are separated, the instant messaging system is only responsible for transmission of the communication content, encryption and decryption of the communication content are conducted by a user or a cryptographic machine developed by another third party. Encryption and decryption algorithms are closed in the cryptographic machine and hidden from the instant messaging system, and the conditions that the communication content is decrypted and recorded by a provider of an instant messaging service and then analyzed and used are avoided. Meanwhile, in order to avoid the risk that secret keys are intercepted and captured when being exchanged in the instant messaging system, the secret keys can be defined by the user and exchanged through a path irrelevant to the instant messaging system. According to the method and system, a series of problems probably caused by the condition that the communication content can be obtained by the provider of the instant messaging service are solved, the distrust sense of safety of network instant messaging of the user is eliminated, and therefore the user can enjoy the network instant messaging service on the subjective feeling and the objective fact.
Description
Technical field
The present invention relates to computer communication field, be specifically related to a kind of instant communication method and system thereof that ensures user communication content safety.
Background technology
Current existing instant communicating system, has mostly adopted various cryptographic algorithm to be encrypted rear transmission to Content of communciation, avoids Content of communciation to be ravesdropping in network transmission process, and this has ensured the safety of Content of communciation to a certain extent.
But, because transmission and the encryption of Content of communciation are all to be completed by instant messaging service provider, cryptographic algorithm is specified or is write by instant messaging service provider, encryption key exchanges between instant communication client and instant communication server end, therefore, Content of communciation ciphertext after instant communication client is encrypted is transferred to after instant communication server end, can be decrypted into expressly by corresponding.Instant messaging service provider expressly records, analyzes the Content of communciation after deciphering, and analysis result is used for to the commercial uses such as accurate advertisement propelling movement, and user has been caused to unnecessary trouble.
Meanwhile, instant messaging service provider's technical capability is also not quite similar, and it is perfectly safe therefore also not necessarily can to accomplish the protection of the Content of communciation of storing.In user communication content, is no lack of privacy of user, the important informations such as trade secret.Once instant messaging service provider's system backstage is dangerous, user communication content just faces by expressly disclosed danger, and this probably causes great loss to user.
Summary of the invention
The object of the invention is to overcome the problem that prior art exists, a kind of instant communication method and system thereof that ensures user communication content safety is provided.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
An instant communication method that ensures user communication content safety, comprises the following steps:
Step 1) instant telecommunication session two parties respectively in the contact list of instant communication client for the other side selects cipher machine;
Step 2) instant communication client (transmit leg) user incoming traffic content is expressly;
By Content of communciation, expressly pass to cipher machine is encrypted to Content of communciation ciphertext to step 3) instant communication client (transmit leg);
Step 4) instant communication client (transmit leg) sends Content of communciation ciphertext;
Step 5) instant communication client (recipient) receives Content of communciation ciphertext;
Step 6) instant communication client (recipient) passes to cipher machine by Content of communciation ciphertext and is decrypted into Content of communciation expressly;
Content of communciation is expressly shown to user by step 7) instant communication client (recipient).
Further, described cipher machine calls for instant communication client as external module, and instant messaging service provider provides cipher machine interface specification, and the developer of cipher machine is instant messaging service provider, user oneself or other any developers.
Further, described method is further comprising the steps of:
Step 1) log-in password machine download interface specification document;
Step 2) exploitation cipher machine;
Step 3) releasing pin machine;
But further, described cipher machine can be inquired about and download from instant communication server end as required in user's use procedure, and instant telecommunication session both sides' cipher machine can be identical, can be also different general mutually.
Further, the generation of the key that described cipher machine is used and exchange are not to be completed by instant communicating system, and key is by User Defined, and by user by other approach; As arranged face to face, the modes such as phone communication complete exchange, the risk of having been intercepted and captured while having avoided key to exchange in instant communicating system; Arrange and memory key for the ease of user, user can input significant random length character string in the time that key is set, as user's birthday by information, then according to default transfer function, this random length character string is converted into the key that cryptographic algorithm needs by cipher machine.
Further, user can be contact object and selects multiple cipher machines and multiple keys are set, to support the multi-enciphering to Content of communciation; Encrypting and decrypting flow process can also be used for other form of session such as group and discussion group except can be used for both sides' session; Content of communciation, except comprising text message, also comprises annex, other Content of communciations such as voice and video.
Ensure an instant communicating system for user communication content safety, comprise instant communication client and instant communication server end, that is:
Described client comprises:
Input unit, for accepting the Content of communciation of user's input;
Cipher machine container, inquires about, downloads, loads, calls and unloads cipher machine for user;
