Title:
SUSTAINABLE OPERATION METHOD BASED ON STS PREPAYMENT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/080409
Kind Code:
A1
Abstract:
A sustainable operation method based on an STS prepayment system is mainly accomplished by means of the following technical solution: the sustainable operation method based on an STS prepayment system comprises the following steps: during switching of a benchmark date, clear a TID stack in a meter and store a secret value; invoke an encryption box according to requirements to obtain a Token0 having a string of 20 numbers, and convert the Token0 into hexadecimal representation; fetch a Token class of 2 bits to obtain a Token0 data cipher text of 64 bits, and add the Token0 data cipher text and the secret value to obtain Token data of 64 bits; insert the fetched Token class of 2 bits into the Token data, and convert same into a Token having 20 numbers; after receiving the Token, the meter parses same to obtain the Token0 and performs CRC verification and TID identification, and after the verification and the identification are successful, the meter stores a TID of the Token0 and executes corresponding operations. By means of the method, the existing STS prepayment system can be used sustainably without replacing the encryption box, and is not affected by the benchmark date.
