20. transmit legs reset the title of bluetooth equipment, and in title, add described enciphered message;
30. transmit legs are opened bluetooth equipments, and bluetooth equipment to be set to user visible;
40. recipients search for bluetooth equipment, and adopt the same key of processing with symmetric cryptography to be decrypted processing to the title of the described bluetooth equipment searching, and obtain decryption information.
Preferably, in described step 10, this carry information to be passed is carried out to symmetric cryptography processing, is mainly by a kind of being encrypted in following algorithm: DES algorithm, IDEA algorithm, RC2 algorithm, RC4 algorithm, SKIPJACK algorithm, RC5 algorithm or aes algorithm.
Preferably, in described step 10, during transmit leg editor carry information to be passed, before described information, be also provided with the first verification head, this the first verification head and described information are carried out symmetric cryptography processing simultaneously, and described enciphered message comprises the first verification head and the described information after encryption.
Preferably, in described step 20, transmit leg adds described enciphered message in title, is also provided with the second verification head before enciphered message, and this second verification head and described enciphered message is set to simultaneously to the title of bluetooth equipment.
Preferably, in described step 40, recipient searches after the title of the described bluetooth equipment that carries the second verification head, and the enciphered message after the second verification head is decrypted to processing, obtains carrying the information of the first verification head, is carry information to be passed.
The invention has the beneficial effects as follows:
A kind of method that transmits fast information by bluetooth of the present invention, it carries out symmetric cryptography processing by treating transmission information, obtain enciphered message, and the enciphered message described in adding in the title of bluetooth equipment, then open bluetooth equipment, it is visible that bluetooth equipment is set to user, recipient adopts the same key of processing with symmetric cryptography to be decrypted processing to the title of the described bluetooth equipment searching, obtain decryption information, without process binding, connect, a plurality of steps such as transmission can complete the transmission of information fast, and fail safe that can guarantee information, make information transmission more quick.
Accompanying drawing explanation
Accompanying drawing described herein is used to provide a further understanding of the present invention, forms a part of the present invention, and schematic description and description of the present invention is used for explaining the present invention, does not form inappropriate limitation of the present invention.In the accompanying drawings:
Fig. 1 is a kind of general flow chart that transmits fast the method for information by bluetooth of the present invention.
Embodiment
In order to make technical problem to be solved by this invention, technical scheme and beneficial effect clearer, clear, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
As shown in Figure 1, a kind of method that transmits fast information by bluetooth of the present invention, it comprises the following steps:
10. transmit leg editor carry information to be passed, and this carry information to be passed is carried out to symmetric cryptography processing, obtain enciphered message;
20. transmit legs reset the title of bluetooth equipment, and in title, add described enciphered message;
30. transmit legs are opened bluetooth equipments, and bluetooth equipment to be set to user visible;
40. recipients search for bluetooth equipment, and adopt the same key of processing with symmetric cryptography to be decrypted processing to the title of the described bluetooth equipment searching, and obtain decryption information.
Symmetric cryptography is mainly a kind of encryption method that adopts one-key cryptosystem, same key can be used as the encryption and decryption of information simultaneously, also referred to as secret key cryptography, so-called symmetrical, adopt exactly both sides' occupation mode of this encryption method to be encrypted and to decipher with same key.Key is the instruction of controlling encryption and decrypting process; This carry information to be passed is carried out to symmetric cryptography processing, is mainly by a kind of being encrypted in following algorithm: DES algorithm, IDEA algorithm, RC2 algorithm, RC4 algorithm, SKIPJACK algorithm, RC5 algorithm or aes algorithm.
In described step 10, during transmit leg editor carry information to be passed, before described information, be also provided with the first verification head, this first verification head and described information are carried out symmetric cryptography processing simultaneously, and described enciphered message comprises the first verification head and the described information after encryption.
In described step 20, transmit leg adds described enciphered message in title, is also provided with the second verification head before enciphered message, and this second verification head and described enciphered message is set to simultaneously to the title of bluetooth equipment.
In described step 40, recipient searches after the title of the described bluetooth equipment that carries the second verification head, and the enciphered message after the second verification head is decrypted to processing, obtains carrying the information of the first verification head, is carry information to be passed.
Below in conjunction with embodiment, further illustrate as follows:
The operating procedure of transmit leg is as follows:
Transmit leg is first inputted the information that needs transmission, be designated as msg1, then to msg1, increase by the first verification head " AA ", be designated as msg2, afterwards msg2 is carried out to symmetric cryptography, as DES, IDEA, RC2, RC4, SKIPJACK, RC5, AES scheduling algorithm all can, content after encryption is designated as msg3, then adds the second verification head " BB " to msg3, is designated as msg4, finally open bluetooth, msg4 is set to bluetooth title and bluetooth is set is that user is visible.
Recipient's operating procedure is as follows:
First open bluetooth search bluetooth equipment around, search the title of bluetooth equipment, be designated as msg4, then judge whether the front two of msg4 is the second verification head " BB ", if not, the next bluetooth equipment of search continued; If so, msg4 is removed to the second verification head " BB ", be designated as msg3, msg3 is carried out to symmetry deciphering, and the information after deciphering is designated as msg2, then judges whether the front two of msg2 is the first verification head " AA ", if not, continue the next bluetooth equipment of search; If so, msg2 is removed to the first verification head " AA ", be designated as msg1, msg1 is the information receiving since then, finally the information after deciphering is preserved, is shown or other operation.
Above-mentioned explanation illustrates and has described the preferred embodiments of the present invention, be to be understood that the present invention is not limited to disclosed form herein, should not regard the eliminating to other embodiment as, and can be used for various other combinations, modification and environment, and can, in invention contemplated scope herein, by technology or the knowledge of above-mentioned instruction or association area, change.And the change that those skilled in the art carry out and variation do not depart from the spirit and scope of the present invention, all should be in the protection range of claims of the present invention.
