ENC Data Protection

Introduction

The IHO Data Protection Scheme defines security constructs and operating procedures that must be followed by Data Servers (providers of data) Data Clients (systems that use the data).

The purpose of data protection scheme is to provide:

1. Piracy Protection: i.e. to prevent unauthorised use of data by encrypting the ENC information.
2. Selective Access: i.e. to restrict access to ENC information to only those cells that a customer has been licenced for.
3. Authentication: i.e to provide assurance that the ENC data has come from approved sources

There are currently two IHO security schemes. The S-63 Scheme, is used for ENC's and ECDIS based on the S-57 Standard. The S-100 Scheme (currently being implemented for testing), is intended for S-100 based products (e.g. S-101, S-102 etc).
