ASN.1
Abstract Syntax Notation One (ASN.1) is a standard interface description language (IDL) for defining data structures that can be serialized and deserialized in a cross-platform way. It is broadly used in telecommunications and computer networking, and especially in cryptography. Protocol developers define data structures in ASN.1 modules, which are generally a section of a broader standards document written in the ASN.1 language. The advantage is that the ASN.1 description of the data encoding is independent of a particular computer or programming language. Because ASN.1 is both human-readable and machine-readable, an ASN.1 compiler can compile modules into libraries of code, codecs, that decode or encode the data structures. Some ASN.1 compilers can produce code to encode or decode several encodings, e.g. packed, BER or XML. ASN.1 is a joint standard of the International Telecommunication Union Telecommunication Standardization Sector (ITU-T) in ITU-T Study Group 17 and ...

Lightweight Directory Access Protocol
The Lightweight Directory Access Protocol (LDAP ) is an open, vendor-neutral, industry standard application protocol for accessing and maintaining distributed directory information services over an Internet Protocol (IP) network. Directory services play an important role in developing intranet and Internet applications by allowing the sharing of information about users, systems, networks, services, and applications throughout the network. As examples, directory services may provide any organized set of records, often with a hierarchical structure, such as a corporate email directory. Similarly, a telephone directory is a list of subscribers with an address and a phone number. LDAP is specified in a series of Internet Engineering Task Force (IETF) Standard Track publications known as Request for Comments (RFCs), using the description language ASN.1. The latest specification is Version 3, published aRFC 4511ref name="gracion Gracion.com. Retrieved on 2013-07-17. (a road map to t ...

ITU-T Study Group 17
The ITU-T Study Group 17 (SG17) is a statutory group of the ITU Telecommunication Standardization Sector (ITU-T) concerned with security. The group is concerned with a broad range of security-related standardization issues such as cybersecurity, security management, security architectures and frameworks, countering spam, identity management, biometrics, protection of personally identifiable information, and the security of applications and services for the Internet of Things (IoT). It is responsible for standardization of i.a. ASN.1 and X.509, it was also the parent body of the Focus Group on Quantum Information Technology (FG-QIT). The group is currently chaired by Arnaud Taddei of Broadcom Europe. Administratively, SG17 is a statutory meeting of the World Telecommunication Standardization Assembly (WTSA), which creates the ITU-T Study Groups and appoints their management teams. The secretariat is provided by the Telecommunication Standardization Bureau (under Director Seizo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
TTCN-3
TTCN-3 ''(Testing and Test Control Notation version 3)'' is a strongly typed testing language used in conformance testing of communicating systems. TTCN-3 is written by ETSI in the ES 201 873 series, and standardized by ITU-T in the Z.160 Series. TTCN-3 has its own data types and can be combined with ASN.1, Interface description language, IDL and XML type definitions. Standard organization ITU-T TTCN-3 standard is part of the Z Series and is organized in several parts: * Z.161 - Core Language defining the core textual notation * Z.162 - Tabular presentation format (TFT) - a way to present the tests in a tabular presentation * Z.163 - Graphical presentation format (GFT) - a way to present the tests graphically with a representation that is similar to the MSC * Z.164 - Operational Semantics - Defines how TTCN-3 is executed * Z.165 - TRI - Defines the API provided and required with a tester * Z.166 - TCI - Defines the API provided and required with a test controller * Z.167 - ASN.1 - De ...
