The present invention relates to a prescription external compounding method based on block chain technology, which releases and generates personal index codes and prescription index codes for the patient's personal information and personal electronic prescriptions through block chain encryption. The degree of encryption is high, and the patient's personal Effective protection of patient information and prescription information to ensure the privacy of patients, while avoiding malicious interception and tampering of patient personal information and prescription information by other institutions.

The present invention relates to the field of encryption control, in particular to a hardware encryption device based on a PROFIBUS bus. The hardware encryption device includes a numerical control unit, an encryption unit and a PROFIBUS bus, and the PROFIBUS bus is respectively connected to the numerical control unit and the encryption unit; wherein, the The numerical control unit sends an operation request to the encryption unit through the PROFIBUS bus, and the encryption unit feeds back encryption state information to the numerical control unit through the PROFIBUS bus according to the operation request. The hardware encryption device implements hardware encryption based on the PROFIBUS bus, which has a high degree of encryption and is difficult to be cracked by violence.

The invention relates to an encryption and decryption system and encryption and decryption method for private data of a mobile phone. Operation authority of private data of a mobile phone is set. A private data definition module is arranged and is used for carry out encryption level definition on the private data of the mobile phone according to the type of the private data as well as an encryption level needed by a user; the private data are stored into a specific private data storage chip; a secret key generation module is used for obtaining a unique identifier ID of the mobile phone, an IEMI number of an SIM card, an SN number of the storage chip of an encrypted data storage module and a first character or last character of a file title of the encrypted data and generating a matrix secret key to carry out encryption and decryption on the private data of the mobile phone. Therefore, the private data of the mobile phone can be encrypted or decrypted rapidly, safely, and stably.

The invention provides a vehicle-mounted antenna and a set top box communication encryption method, belongs to the communication encryption technology field and solves a problem that communication between a vehicle-mounted set top box and the vehicle-mounted antenna can be easily copied and monitored. The method comprises steps that A, a same set of plain text segments is commonly taken by the antenna and the set top box as a fixed code on the basis of mutual agreement; B, a random code containing a self ID number is sent and read by the set top box to the vehicle-mounted antenna, the random code and the fixed code are received by the vehicle-mounted antenna and are combined to form a corresponding plain text, a query code is calculated, and the query code acquired through calculation is returned to the set top box; C, according to the random code and the fixed code, the set top box carries out calculation and combination in the same mode to form a corresponding plain text, and a check code is calculated; and D, the query code is compared with the check code, if the two are completely identical, the set top box is activated and starts normal operation, if not, waiting continues. Through high-intensity encryption behaviors of the set top box and the antenna, communication can not be copied or monitored, and the set top box can be effectively prevented from being illegally used for other purposes.
