Electronic aircraft maintenance record signature technology based on SM2 cryptographic algorithm

Abstract

The paperlessness of maintenance records is an inevitable trend in the development of civil aviation informationization. This paper proposes a method for the use of reliable electronic signatures for electronic records in maintenance paperless, and uses domestic cryptographic algorithms to propose electronic signatures for maintenance records. And for the specific work scenario of maintenance, the special signature idea of structured data and layout archive synchronous double signature is proposed. The electronic maintenance record signature method based on SM2 algorithm proposed in this paper is applied in the construction of an airline’s electronic signature system.
