Design and Implementation of Cryptographic Taximeter Sensor Based on EFM32 MCU
XI Wei-hu · Journal of Hunan Institute of Engineering · 2013
This paper introduces the cryptographic taximeter sensor based on EFM32MCU.Pulse data after being encrypted transfer via a serial port to the taximeter can put an end to the possibility of the taximeter sensor being implanted pulse,deprived of data,falsified or replaced.The encrypted sensor has greatly increased the billing accuracy and safety of the taximeter.
