Abstract
The invention aims to provide a combined commodity security system, namely a one-way function bidirectional encryption based electronic commodity security system. The electronic commodity security system comprises an RFID (radio frequency identification device) read-write device, an RFID reader, a random number generator, a system server and RFID electronic tags arranged on commodities, and each commodity corresponds to a length of message MAi composed of serial numbers. Before delivery, each commodity generates a length of the serial numbers along with the random number generator to be used as digital signatures of the MAi. The MAi is subjected to one-way function calculation to acquire CAi=H1(MBi), and the MBi is subjected to one-way function calculation to acquire CBi=H2(MBi). The combined message is acquired as follows: K1i=MAi&CBi and K2i=CAi&MBi. Before delivery of each commodity, the RFID electronic tags are pre-written into the combined message of K1i, and the combined message of K2i is stored in the system server.
