Project: Location Independent Information Object Security
(IOS)

Bolt Beranek and Newman, Inc. (BBN), under contract to the
Advanced Research Projects Agency (ARPA), has developed the
Information Object Security (IOS) Tools.  These tools use
object identifiers which are registered as Computer Security
Objects.  ARPA has unlimited rights in the software
containing the objects.  BBN specified, created, and named
the objects under contract to ARPA, and remains the primary
point of contact on all questions regarding naming
conflicts.  The NIST Computer Security Objects Register
(CSOR) assumes no responsibility pertaining to any inquiry
regarding ownership or naming conflicts. 

The IOS software is publicly available and can be obtained
on the Internet for anonymous ftp at ests.bbn.com.

IOS component list encoded as an ASN.1 stream.  

The syntax for a component list is as follows:


    ComponentList ::= SEQUENCE {
     version     IOS-Version DEFAULT 0,
        list        SEQUENCE OF Components }

    Components ::= SEQUENCE {
     componentType  OBJECT IDENTIFIER
     ios-component  ANY DEFINED BY componentType }

    IOS-Version ::= INTEGER { 0 (0)}
