Overview[]
The Information Object Security (IOS) Program (also referred to as the Information Object Security (IOS) project) is a multi-year effort to investigate and develop advanced security services to the Internet sponsored by the Advanced Research Project Agency (ARPA) and the Air Force. The architecture developed consists of sequences of components specified in ASN.1. Each component, and subsequent sub-type, carries an object identifier. Most of the components are directly related to security, e.g. the confidentiality Component. Other components are indirectly related to security, but are included because they support the definition of the parent object.
The information required for the registration of IOSP objects is limited to details necessary to correctly implement the objects.
