Define those TTP services needed to support the application of digital signatures for the purpose of non-repudiation of creation of documents. This document will also define interfaces and protocols to enable interoperability between entities associated with these TTP services. Definitions of technical services and protocols are required to allow for the implementation of TTP services and related commercial applications. This standard focuses on (1) implementation and interoperability, (2) service specifications, and (3) technical requirements.

This part of ISO/IEC 15946 specifies public-key cryptographic techniques based on elliptic curves. They include the establishment of keys for secret-key systems, and digital signature mechanisms. This part of ISO/IEC 15946 describes mechanisms for digital signatures. The mathematical background and general techniques necessary for implementing the mechanisms are described in part 1 of ISO/IEC 15946.

Specifies the physical and magnetic characteristics of a 12,7 mm wide, 448-track magnetic tape cartridge, to enable physical interchangeability of such cartridges between drives. It also specifies the quality of the recorded signals, a format - called Super Digital Linear Tape 1 (SDLT 1) - and a recording method, thereby allowing data interchange between drives. Together with a labelling standard, for instance ISO 1001 for Magnetic Tape Labelling, it allows full data interchange by means of such magnetic tape cartridges.
