Physical Standards

Document Number	Title	Description
ISO 21217	Intelligent transport systems –– Communications access for land mobiles (CALM) –– Architecture	ISO 21217 describes the communications reference architecture of nodes called "ITS station units" designed for deployment in ITS communication networks. While it describes a number of ITS station elements, whether or not a particular element is implemented in an ITS station unit depends on the specific communication requirements of the implementation. It also describes the various communication modes for peer–to–peer communications over various networks between ITS communication nodes. These nodes may be ITS station units as described in the document or any other reachable nodes. ISO 21217 specifies the minimum set of normative requirements for a physical instantiation of the ITS station based on the principles of a bounded secured managed domain.
NIST FIPS PUB 140–2	Security Requirements for Cryptographic Modules	This Federal Information Processing Standard (140–2) specifies the security requirements that will be satisfied by a cryptographic module, providing four increasing, qualitative levels intended to cover a wide range of potential applications and environments. The areas covered, related to the secure design and implementation of a cryptographic module, include specification; ports and interfaces; roles, services, and authentication; finite state model; physical security; operational environment; cryptographic key management; electromagnetic interference/electromagnetic compatibility (EMI/EMC); self–tests; design assurance; and mitigation of other attacks.
