However, even Esri's shapefile is being challenged by the OGC's latest Geopackage standard (GPKG
), which packs raster, vector and symbology data in an object database format, to ease information exchanges between heterogeneous environments.
We also set up a Global PKG (GPKG) as the global trusted authority to authenticate PKGs in different domains.
The process of cloud entity authorization includes two parts: GPKG authorizes PKG in each SD; PKG authorizes cloud entities, such as users and service providers (SPs) in its own SD.
PKG registers its identifiable information at GPKG. GPKG authenticates the identifiable information and generates a public key [ID.sub.PKG] = ([id.sub.PKG], T) for the PKG, where T represents the valid period of [ID.sub.PKG] and [id.sub.PKG] the PKG's identifiable information.
Based on the BF-IBE scheme , GPKG computes G([K.sub.GKPG], [P.sub.GPKG], [ID.sub.PKG]) to generate the private key [K.sup.-.sub.PKG] corresponding to IDPKG, where KGPKG is the GPKG's master key and PGPKG the public parameter generated by GPKG.
GPKG generates an authentication vector [V.sub.RPKG] = ([K.sup.-.sub.RPKG], [P.sub.GPKG], [ID.sub.GPKG], RAI) and binds it to the PKG via a secure channel (either based on smartcards or security protocols), where [ID.sub.GPKG] is the GPKG's identity and RAI the register area identifier allocated by GPKG.
PKG-A sends a request vector to PKG-B: [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII], where P is the public parameter generated by GPKG.
Our security architecture includes two-level trust nodes: GPKG in the global security domain (GSD) and PKG in the lower-level security domain (LSD).
The Open Geospatial Consortium (OGCA) seeks public comments on the current draft of the candidate OGC GeoPackage (GPKG) Standard.
The GeoPackage container and related GPKG SQLite Extension configuration and API will increase the cross-platform interoperability of geospatial applications and web services in the mobile world.
