Detailed Description

Default implementation that checks whether a position lies within a certificate's GeographicRegion. Supports: no restriction, CircularRegion, RectangularRegion, PolygonalRegion, IdentifiedRegion (only ISO 3166/M49 country codes). For unsupported IdentifiedRegion variants, the permissive flag controls their acceptance or rejection. IdentifiedRegion (ISO 3166 country codes): unsupported; returns false (conservative) unless Entirely unknown region types are always rejected conservatively.

◆ set_permissive_identified_region()

void vanetza::security::v3::DefaultLocationChecker::set_permissive_identified_region ( bool permissive)
inline

Change permissive behaviour regarding unsupported IdentifiedRegion types.

When set to true, unsupported IdentifiedRegion (country and region, country and sub-regions) are not checked but still accepted. These regions are only defined for the United States, i.e. they have no meaning for European C-ITS deployments. Default behaviour is conservative rejection (false), user must explicitly opt in.

Definition at line 72 of file location_checker.hpp.

◆ use_country_database()

void vanetza::security::v3::DefaultLocationChecker::use_country_database ( const geodesy::CountryDatabase * db)
inline

Register country database for IdentifiedRegion validations.

If a database is registered, validation of countryOnly IdentifiedRegion takes place. If database is missing, validation falls back to the defined permissive behaviour.
