Provides definition of guidelines for specifying the abstract syntax of generic and specific Security Information Objects (SIOs) for Access Control; the specification of generic SIOs for Access Control; the specification of specific SIOs for Access Control. The scope of this Recommendation | International Standard covers only the "statics" of SIOs through syntactic definitions in terms of ASN.1 descriptions and additional semantic explanations. It does not cover the "dynamics" of SIOs, for example rules relating to their creation and deletion. The dynamics of SIOs are a local implementation issue.

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.

International Standard ISO/IEC 15946 specifies public key cryptographic techniques based on elliptic curves. The standard is split into four parts and includes the establishment of keys for secret key systems and digital signature mechanisms. This part of ISO/IEC 15946 specifies techniques for key establishment, which includes key agreement and key transport, that use elliptic curves.

Specifies the mechanical, physical and optical characteristics of a 80 mm, read-only optical disk to enable the interchange of such disks. It specifies the quality of the recorded signals, the format of the data and the recording method, thereby allowing for information interchange by means of such disks.

This International Standard specifies the physical and magnetic characteristics of magnetic tape cartridges, using magnetic tape 12,65 mm wide so as to provide physical interchange of such cartridges between drives. It also specifies the quality of the recorded signals, the recording method and the recorded format, thereby allowing data interchange between drives by means of such cartridges. The format supports variable length Logical Records, high speed search, and the use of a registered algorithm for data compression.

Specifies a lossless compression algorithm to reduce the number of 8-bit bytes required to represent data records and File Marks. The algorithm is known as Streaming Lossless Data Compression algorithm (SLDC). One buffer size (1 024 bytes) is specified. The numerical identifier according to ISO/IEC 11576 allocated to this algorithm is 6.

Specifies the mechanical, physical, and optical characteristics of a 130 mm optical disk cartridge (ODC) that employs thermo-magnetic and magneto-optical effects to enable data interchange between such disks. This International Standard specifies two Types, viz. Type R/W provides for data to be written, read and erased many time over the recording surface(s) of the disk.

Specifies the mechanical, physical, and optical characteristics of a 130 mm optical disk cartridge (ODC) that employs thermo-magnetic and magneto-optical effects to enable data interchange between such disks. This International Standard specifies two Types, viz. Type R/W provides for data to be written, read and erased many time over the recording surface(s) of the disk. Type WO provides for data once written to be read a multiplicity of times. Data shall not be erased nor amended. Multisession (incremental write operations) recording may be performed on type WO disks. The disk shall be of the same Type if recorded on both sides, A and B. Each side shall have a nominal capacity of 4,58 Gbytes, irrespective of the Type. The format specifies two sector sizes and allows for emulation of two further sizes.

Thin flexible cards, the subject of this International Standard, are used to automate the controls for access to goods or services such as mass transit, highway toll systems, car parks, vouchers, stored value, etc. For these applications, data can be written and/or read by machines using various recording techniques such as magnetic stripe, optical character recognition (OCR), bar code, etc. This part of ISO/IEC 15457 specifies the test methods and procedures required to carry out measurements of the magnetic stripe and encoding characteristics of thin flexible cards.

Specifies a metadata system for describing multimedia content. It specifies the Description Definition Language (DDL) that comprises part 2 of the standard (ISO/IEC 15938-2). The goal of this part of the MPEG-7 International Standard is to specify a language that will enable MPEG-7 users and developers to: create valid MPEG-7 description schemes and descriptors; develop tools such as editors and parsers for processing descriptions, description schemes and descriptors; generate refinements, extensions and modifications to the DDL. Describes the features of the DDL. It defines the syntax of the DDL constructs and datatypes and provides optional (informative) examples that illustrate the application of the DDL to the specification and instantiation of MPEG-7 descriptions.

Defines a Multimedia Content Description Interface, specifying a series of interfacesfrom system to application level to allow disparate systems to interchange information about multimedia content. Itdescribes the architecture for systems, a language for extensions and specific applications, description tools in theaudio and visual domains, as well as tools that are not specific to audio-visual domains. As a whole, thisInternational Standard encompassing all of the aforementioned components is known as 鬗PEG-7.?MPEG-7 isdivided into eight parts (as defined in the Foreword).This part of the MPEG-7 Standard (Part 4: Audio) specifies description tools that pertain to multimedia in the audiodomain. See below for further details of application.This part of the MPEG-7 Standard is intended to be implemented in conjunction with other parts of the standard. Inparticular, MPEG-7 Part 4: Audio assumes knowledge of Part 2: Description Definition Language (DDL) in itsnormative syntactic definitions of Descriptors and Description Schemes. This part of the standard also hasdependencies upon clauses in Part 5: Multimedia Description Schemes, namely many of the fundamentalDescription Schemes that extend the basic type capabilities of the DDL.MPEG-7 is an extensible standard. The method to extend the standard beyond the Description Schemes providedin the standard is to define new ones in the DDL, and to make those DSs available with the instantiateddescriptions. Further details are available in Part 2. To avoid duplicate functionality with other parts of the standard,the DDL is the only extension facility provided.

Associated with the provision and operation of a Trusted Third Party (TTP) are a number of security-related issues for which general guidance is necessary to assist business entities, developers and providers of systems and services, etc. This includes guidance on issues regarding the roles, positions and relationships of TTPs and the entities using TTP services, the generic security requirements, who should provide what type of security, what the possible security solutions are, and the operational use and management of TTP service security.
