Abstract
The invention discloses an authorization and encryption method for controlling blacklist setting of an intelligent lock. In the method, the blacklist and an authorized user ID after being bound are encrypted through a RSA public key to form an encrypted cryptograph; a mobile phone current user ID and the encrypted cryptograph are combined to compose a communication data packet; the communication data packet is sent to a Bluetooth intelligent lock through a Bluetooth; the Bluetooth intelligent lock decrypts the communication data packet by using a corresponding RSA private key in the lock and compares the current user ID with the authorized user ID; if the current user ID is as same as the authorized user ID, the blacklist is written in the lock rather than a nonvolatile memory; otherwise, a blacklist write-in command is not executed. The authorization and encryption method for controlling the blacklist setting of the intelligent lock can efficiently prevent an unauthorized ID from setting the blacklist.

Summary of the invention
Present invention aim to provide a kind of blacklist controlling smart lock to arrange mandate and encryption method, the method uses RSA, and (name of algorithm is named after its inventor: Ron Rivest, AdiShamir and Leonard Adleman) asymmetric encryption and decryption method, PKI is used for encrypting, private key is used for deciphering, public, the diverse key of private key spoon, simultaneously by authorized user ID (Identity, identity number) encrypt with the blacklist binding that need to arrange, blacklist can be solved well mandate and the problem of blacklist communication encryption are set.
For realizing this purpose, the blacklist controlling smart lock designed by the present invention arranges mandate and encryption method, it is characterised in that it comprises the steps:
Step 1: mobile phone electronic key management application program obtains rsa encryption PKI A；
Step 2: mobile phone electronic key management application program uses described rsa encryption PKI A encryption authorization ID and needs the blacklist name arranged, and generates encrypted cipher text B；
Step 3: when mobile phone electronic key management application program is configured blacklist operation, takes mobile phone electronic key management application program active user ID and encrypted cipher text B and forms communication bag, is sent to blue-tooth intelligence lock；
Step 4: after blue-tooth intelligence interlocking receives the communication bag that mobile phone electronic key management application program is sent, RSA private key preset in using blue-tooth intelligence lock deciphers described encrypted cipher text B；
Step 5: blue-tooth intelligence lock internal program compares authorized user ID and active user ID, if unanimously, then performs to write blacklist operation；If it is inconsistent, do not perform to write blacklist operation.
It is characteristic of the invention that and use RSA public key encryption after authorized user ID and blacklist binding, the lock of RSA PKI only purchase lock is main just to be had, so only locking user that is main or that lock main mandate can arrange blacklist, other users can be avoided to abuse this function；Another feature of the present invention is mobile phone A PP when lock sends blacklist order, in addition to sending ciphertext B of previous step, also will send APP ID at that time, will compare the two ID, and can effectively prevent unauthorized ID to arrange blacklist when processing in lock.
