Data Server Term used to represent an organisation producing encrypted ENCs or issuing Cell Permits to end-users. M_ID The unique identifier assigned by the SA to each manufacture. Data Servers use this to identify which M_KEY to use when decrypting the Userpermit. M_KEY ECDIS manufacturer’s unique identification key provided by the Scheme Administrator to the OEM. It is used by OEMs to encrypt the HW_ID when creating a userpermit. HW_ID The unique identifier assigned by an OEM to each implementation of their system. This value is encrypted using the OEM’s unique M_KEY and supplied to the data client as a userpermit. This method allows data clients to purchase licences to decrypt ENC cells. SA Scheme Administrator SHA-1 Secure Hash Algorithm [3] SSK Self Signed Key (Self Signed Certificate File) User Permit Encrypted form of HW-ID uniquely identifying the ECDIS system Chart Related Terms ECDIS Electronic Chart Display and Information System as defined by IMO ENC Electronic Navigational Chart as defined by the ENC Product Specification [1].
