摘　　要：不同坐标系成果之间的转换是测量工作中必不可少的环节。基于转换参数保密的需求,如何确保转换参数不被泄密是坐标转换过程中需要解决的问题。本文基于新一代加密狗的特点,提出利用加密狗对转换参数加密和存储,并将坐标转换或混淆的代码移植到加密狗内,实现了省级海量参数的加密、管理和调用,有效杜绝了转换参数和坐标转换过程的泄密,大大提高了保密强度。The transformation between different coordinate system results is an indispensable link in surveying work. Based on the requirement of confidentiality of conversion parameters, how to ensure that conversion parameters are not leaked is a problem to be solved in the process of coordinate transformation. Based on the characteristics of the new generation of dongle, this paper proposes to use the dongle to encrypt and store the conversion parameters, and transplant the coordinate conversion or confused code into the dongle. It realizes the encryption, management and invocation of provincial massive parameters, effectively eliminates the leakage of conversion parameters and coordinate conversion process, and greatly improves the security intensity.
