Industrial Automatic Control Systems and Controllers Annotation << Back Software and Hardware Complex to Prevent Thefts of Bikes Based on the Use of Authentication RFID Card A.V. Yakovlev, E.O. Vasyukova Software and hardware complex designed to reduce the number of Bicycle thefts, as well as enable the recovery of a stolen bike with a DB through the use of RFID tags. The original idea is to combine RFID card holder and RFID tag device functions identifi cation and authentication and, consequently, decision-making hardware and software system for unlocking the locking device of the Bicycle. An analysis was conducted of the most well-known hash functions on the number of collisions when processing large number of records. Based on the result of the comparison and analysis of the scientifi c literature for the encryption was chosen as SHA-3 with a key length of 224 bits. Modeling a hardware-software complex is implemented on basis of controller ArduinoUno and RFID reader (RFID-RC522) to control the led and servo unlock lock velepromet. Keywords: software and hardware complex; RFID device identifi er; a cryptographic salt; electromagnetic induction; hash function; SHA-3; generator random sequence; the controller ArduinoUNO; the reader of RFID-RC522.
