Hello Vinod and Franck,
Actually, SENC stands for System ENC.
SENC are the internal chart database proprietary formats specific to
the different developers of ECS (Electronic Chart System) or ECDIS
(Electronic Chart Display and Information System) software
applications, created from decrypted ENC files which can be in non
protected s-57 open exchange format (used by NOAA) or in s-63
encrypted format, IHO (International Hydrographic Organization) Data
Protection Scheme for the protection of ENC information by most of the
other Hydrographic Services and distributed by Primar and IC-ENC.
s-63 defines security constructs and operating procedures that must be
followed to ensure that the data protection scheme is operated
correctly and to provide specifications that allow participants to
build compliant systems.
Regarding s-63 implementation, see :
