Information technology — ASN.1 encoding rules: Specification of Basic Encoding Rules (BER), Canonical Encoding Rules (CER) and Distinguished Encoding Rules (DER) — Part 1: ISO/IEC 8825-1:2008

Publication date:   Dec 15, 2008

Scope

ISO/IEC 8825-1:2008 specifies a set of basic encoding rules that can be used to derive the specification of a transfer syntax for values of types defined using the notation specified in ISO/IEC 8824-1, ISO/IEC 8824-2, ISO/IEC 8824-3, and ISO/IEC 8824-4, collectively referred to as Abstract Syntax Notation One or ASN.1. These basic encoding rules can also be applied for decoding such a transfer syntax in order to identify the data values being transferred. ISO/IEC 8825-1:2008 also specifies a set of canonical and distinguished encoding rules that restrict the encoding of values to just one of the alternatives provided by the basic encoding rules.
