Copyright infringement and data piracy are pervasive problems of the digital era. In order to avoid unofficial distribution of nautical information and ensure the authority and integrity of data, the International Hydrographic Organization issued S-63 Data Protection Scheme. This scheme makes sure the authority of data via digital signature and authentication algorithm, and improves confidentiality of data via encryption algorithm, and guarantees the integrity of data via secure hash algorithm. This paper gives a detailed description of framework and workflow of S63 data protection scheme, and analyzes the algorithms that used in S63 and its security. The key parameters of the algorithms are specified. Afterwards, this paper discusses the implementation of S-63 in ECDIS; transform S63 data into S57 data. Application results show that the method is suitable and efficient.
