In the invention, the security chip is arranged in the mobile terminal for encryption signature or decryption identification of the received and transmitted wireless data; encryption is realized by the hardware, thus the data encrypted transmission speed is improved, the encryption to the whole data flow is realized and the security of wireless data transmission is guaranteed.
Description
Technical field
The present invention relates to a kind of method of data transmission security, specifically relate to a kind of method and a kind of portable terminal that improves wireless data transmission security that improves wireless data transmission security.
Background technology
The movable computer of various hand-held mobile terminals such as mobile phone, PDA (personal digital assistant) and other wireless Internet accesses, the network insertion service that provides a convenient and great mobility.But in actual use, fail safe, the confidentiality of wireless data transmission have been subjected to people's attention, have limited the interest of people to its use.With respect to data wire transmission, the data of wireless data transmission process are easier is stolen, reads, distorts by the disabled user etc.Utilizing the data encryption solution is the important means of the safety of protection digital information.For portable terminal, prior art solutions generally is that user's download is used special encrypt/decrypt program, by moving these software programs information data is carried out encrypt/decrypt and transmission, prevents disabled user's awareness information content.And these softwares are attacked by illegal program easily, in case these softwares are caught virus, safety of data then can not get ensureing.
Summary of the invention
The objective of the invention is to propose a kind of portable terminal that improves wireless data transmission security, be built-in with safety chip, improve the data wireless safety of transmission.
The present invention also proposes a kind of method that improves wireless data transmission security.
The portable terminal of raising wireless data transmission security of the present invention is solved by the following technical programs.
The portable terminal of this raising wireless data transmission security, comprise control chip, the wireless communication module that is connected with control chip and memory, it is characterized in that, also comprise the safety chip that is connected with control chip, have embedded encrypting and decrypting program in the described safety chip.
The portable terminal of above-mentioned raising wireless data transmission security also stores customer identification information in the wherein said safety chip.
Described safety chip also is connected with memory.
A kind of method that improves the invalid data transmission security that the present invention proposes is achieved by the following technical programs.
The method of this raising wireless data transmission security may further comprise the steps: portable terminal receiving radio data step: the control chip of portable terminal is given safety chip with the wirelessly transmitting data flow transmission that receives, safety chip carries out giving control chip with data flow transmission behind the decryption verification to data stream, and the data flow of control chip after with decryption verification is stored in the memory; Portable terminal sends the wireless data step: the control chip of portable terminal reading data flow and give safety chip with data flow transmission from memory, give control chip with data flow transmission after safety chip is encrypted data stream, control chip sends data encrypted stream by wireless communication module.
The method of above-mentioned raising wireless data transmission security, wherein, in the described portable terminal receiving radio data step, the data flow of safety chip after with decryption verification directly exported and is stored in the memory.
Described portable terminal sends in the wireless data step, control chip notice safety chip reading data flow from memory, and control chip is transferred to control chip after data stream is encrypted again.
Described portable terminal sends in the wireless data step, and safety chip also writes customer identification information in the data flow, to being transferred to control chip again behind the data flow signature.
The present invention is compared with the prior art the beneficial effect that is had to be had: safety chip is set in portable terminal, the wireless data of accepting and send is carried out ciphering signature or decryption verification, adopt hardware encipher, in the process of transfer of data, simultaneously data are carried out encrypt/decrypt, not only improved the data encryption transmitting speed, and can encrypt entire stream, guaranteed the data wireless safety of transmission.
Description of drawings
Fig. 1 is the module composition diagram of portable terminal in the embodiment.
Embodiment
A kind of portable terminal as shown in Figure 1 comprises control chip (CPU), memory, and is connected with wireless communication module by wireless communication interface circuit, also is provided with safety chip, and safety chip is connected with control chip by parallel bus.Control chip is used for the acceptance and the transmission of control data, and safety chip has embedded encrypting and decrypting program, and stores information such as user identity identification, is used to realize the encrypting and authenticating of data.
When portable terminal sent data, control chip is reading data flow from memory, and gave safety chip with data flow transmission.Safety chip is encrypted data stream, and storage user profile is within it added in the data flow, will give control chip through the data flow transmission of encrypted authentication then.Control chip sends data encrypted stream by wireless communication module.
When portable terminal received data, control chip control wireless communication module received wirelessly transmitting data, gives safety chip with the wirelessly transmitting data flow transmission that receives then.Safety chip carries out decryption verification to data stream, if decryption verification failure then clears data and points out; If the decryption verification success, the data flow transmission after then will deciphering is given control chip.The data flow output of control chip after with decryption verification is stored in the memory.
In the another kind of execution mode, after portable terminal received data, the data flow of safety chip after with decryption verification directly output was stored in the memory.When portable terminal sends data, control chip control safety chip reading data flow from memory, control chip is transferred to control chip after data stream is encrypted again.Can reduce the transfer of data of safety chip and control chip like this, raising speed.
Memory comprises the built-in or external buffer memory of portable terminal, internal memory, flash memory or portable hard drive etc.
Above method can be applied to WPA (Wi-Fi Protected Access, Wi-Fi Protected Access) solution, WEP (Wired Equivalent Privacy, Wired Equivalent Privacy) encryption technology, strengthens the fail safe of wireless transmission.Because the encrypting and decrypting program realizes by safety chip hardware, has guaranteed safety of data, as in asymmetric is encrypted, the key of generation can not be transferred to chip exterior.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
