摘　　要：长江电子航道图中涵盖了多种要素及其属性,是指导船舶安全航行的必备重要信息。但根据相关保密法律法规中的规定,部分要素及其属性属于涉密内容,不能对外公开。为了既保证数据的规范性又保证数据的安全性,在充分分析相关保密法律法规和航道要素及其属性的基础上,对长江电子航道图航道要素密级及脱密处理方法进行研究,规定涉密要素及其属性的取舍情况。在保证对外发布数据安全性的同时,确保长江电子航道图能够正确指导船舶用户安全航行。ChangJiang Electrouic Navigational Chart（CJENC） covers a variety of elements and attributes which are essential and important information to guide safe vessel navigation. But according to related confidentiality laws and regulations, some of the elements and attributes belong to confidential content and can＇ t publish externally. In order to ensure normalization and security of the data, based on a comprehensive analysis of related confidentiality laws, regulations, waterway elements and attributes, this paper probes into the security classification and decryption processing method about waterway elements of CJENC. It can ensure that the CJENC guides safe navigation of vessels. Meanwhile, the security of data publishment is guaranteed.
