Specifies the cryptographic functions for establishing symmetric keys using a lattice-based polynomial public key encryption algorithm and the associated parameters for key generation (see Note 1). The mechanism supported is key transport, where one party selects keying material and conveys it to the other party with cryptographic protection. The keying material may consist of one or more individual keys used to provide other cryptographic services outside the scope of this Standard, e.g. data confidentiality, data integrity, or symmetric-key-based key establishment. The standard also specifies key pair generators and corresponding key pair validation methods supporting the key transport schemes

ISO/IEC TR 11580:2007 defines a format for describing user interface objects, actions and attributes. It provides a basis for standardizing the names and properties of user interface objects, actions and attributes across multiple applications and platforms.

ISO/IEC TR 11580:2007 contains guidance both on the standardization of user interface objects, actions and attributes and on the implementation of these objects, actions and attributes in any or all modalities. It is primarily intended for developers of standards, style guides and architectures involving user interface objects, actions and attributes.

ISO/IEC TR 11580:2007 also provides software developers with a range of functionalities to be considered in the design of objects, actions and attributes within user interfaces.

Different users of information technology products possess different sets of abilities. Some abilities may not ever be present in a user as they may have been born without them. Some abilities are acquired, developed or deteriorate over time due to education, maturity, injury, illness or age. Just as it is possible that a user possesses a combination of abilities, it is also possible that they may lack a combination of abilities.

ISO/IEC TR 19765:2007 presents icons and symbols currently used to provide access to facilities and tools to support the needs of elderly and disabled users of information technology (IT) products, and could form the basis of a future International Standard which would provide a recommended collection of icons and symbols.

These icons and symbols have been collected from a variety of sources including other standards, contemporary software products, web sites and hardware devices. These sources are cross-referenced and listed in a bibliography.

The icons and symbols presented in ISO/IEC TR 19765:2007 are categorized by modality and method of use.

ISO/IEC 29112 defines methods for the objective measurement of the print quality characteristics that contribute to the perceived resolution of reflection mode monochrome printed pages produced by digital electro-photographic printers.

The measurement methods used in ISO/IEC 29112 are derived from several existing techniques for the assessment of an imaging system's resolution characteristics. Each of these measurement methods is intended for the engineering evaluation of a printing system's perceived resolution and not for purposes of advertising claims.

The methods are applicable only to monochrome prints produced in reflection mode by electro-photographic printing technology.

ISO/IEC 29112 is intended for monochrome printers utilizing postscript interpreters capable of accepting postscript and encapsulated postscript (EPS) jobs.

This Technical Report complements ISO 8879 by providing additional turorial information. It is not intended, and should not be regarded, as an extention, modification, or interpretation of ISO 8879. The SGML language contains a number of components, some of which are optional features. The tutorial information covers the main components of the language only; notably a discussion of LINK, CONCUR, and DATATAG is outside the scope of this Technical Report.

The intended audience is mainly document type designers already familiar with the basic concepts of SGML, but requiring more tutorial information on techniques for using SGML for various applications. Subclauses 5.3 and 8.4 are written in the style of a “User Guide” and can be used as a basis for end-user documentation. For an introductory tutorial on SGML the annexes of ISO 8879 can be used.

This Technical Report includes notes on the analysis of a document prior to the writing of a formal document type definition, and a series of examples.

The principal example is for a general document type, formally defined as an example in clause E.1 of ISO 8879. Others of a general nature are for letter and memorandum, spreadsheet, mathematics, and the mixing of text and graphics. Those for language applications include Scandinavian runes, Japanese, a European multilingual document, and mixing text in languages written from left to right and from right to left.

Specifies Twisted Pair Physical Layer Medium Dependent (TP-PMD) requirements for the Fibre Distributed Data Interface (FDDI). FDDI provides a high-bandwidth (100 Mbit/s) general-purpose interconnection among computers and peripheral equipment using fibre optics and twisted pair as the transmission medium. FDDI can be configured to support a sustained data transfer rate of at least 80 Mbit/s (10 Mbyte/s). It may not meet the response time requirements of all unbuffered high-speed devices. FDDI provides connectivity for many nodes distributed over distances of several kilometers in extent. Default values for FDDI were calculated on the basis of 1 000 physical links and a total fibre path length of 200 km (typically corresponding to 500 nodes and 100 km of dual fibre cable).

Establishes a structure for the assignment of identifying data codes to locational entities in the United States and its outlying and associated areas, for the purpose of information interchange among data-processing systems. Types of locational entities for which this strucutre is intended include (but are not limited to) populated places, primary county divisions such as townships and New England towns, Indian reservations, and facilities such as airports and military bases. This standard also establishes requirements for associated data that improve the utility of the primary data codes.
