An Optimization of Credit-Based Payment for Electronic Toll Collection Systems

摘要

Credit-based electronic payment systems are considered to play important roles in future automated pay- ment systems. Like most other types of payment system, how- ever, credit-based systems proposed so far generally involve com- putationally expensive cryptographic operations. Such a rela- tively heavy computational load is preventing credit-based sys- tems from being used in applications which require very fast pro- cessing.
