Abstract

The invention provides a method and device for verifying chip data of a temperature recorder based on a block chain. The method comprises the steps that a secret key corresponding to a temperature sensor chip is generated according to a unique identifier UID of the temperature sensor chip of the temperature recorder, a user acquires the unique identifier UID of the temperature sensor chip and judges whether the temperature sensor chip exists or not based on a block chain, a server calculates a first signature, the temperature sensor chip calculates a second signature, and it is judged whetherthe first signature is equal to the second signature or not, and if so, the verification of the temperature sensor chip is past. According to the scheme of the invention, compared with the prior art,the temperature recorder does not need to be provided with a complex temperature sensor chip, a complex algorithm does not need to be designed for the temperature sensor chip, the temperature sensor chip of the temperature recorder used in cold chain transportation can be verified, and therefore it is guaranteed that data in the temperature recorder is safe and credible, and data tracking and tracing are easy to achieve.

Description

technical field [0001] The invention relates to the field of the Internet of Things, in particular to a method and device for verifying chip data of a temperature recorder using a block chain. Background technique [0002] At present, with the development of the logistics transportation network and the increasing demand for various goods, cold chain transportation has become a common mode of transportation. Cold chain transportation can be used in road transportation, water transportation, railway transportation, and air transportation. Either way, it can also be a comprehensive mode of transport combined with multiple modes of transport. Cold chain transportation technology can be used to deliver various vegetables, fruits, meat and other fresh foods and various quick-frozen foods and other processed foods from production sites thousands of miles away to local supermarkets or consumers' homes through the Internet of Things. In addition, some medicines and medical devices t...
