ISO 8825:2021 Information technology – ASN.1 encoding rules – Part 7: Specification of Octet Encoding Rules (OER)
CDN $263.00
Description
This document specifies a set of Basic Octet Encoding Rules (BASIC-OER) that may be used to derive a transfer syntax for values of the types defined in Rec. ITU-T X.680 | ISO/IEC 8824-1, Rec. ITU‚ÄëT X.681 | ISO/IEC 8824-2, Rec. ITU-T X.682 | ISO/IEC 8824-3, Rec. ITU-T X.683 | ISO/IEC 8824-4. This document also specifies a set of Canonical Octet Encoding Rules (CANONICAL-OER) which provides constraints on the Basic Octet Encoding Rules and produces a unique encoding for any given ASN.1 value. It is implicit in the specification of these encoding rules that they are also to be used for decoding.
The encoding rules specified in this document:
–      are used at the time of communication;
–      are intended for use in circumstances where encoding/decoding speed is the major concern in the choice of encoding rules;
–      allow the extension of an abstract syntax by addition of extra values for all forms of extensibility described in Rec. ITU-T X.680 | ISO/IEC 8824‑1.
