This standard is for a Protection Profile for Hardcopy Devices in a restrictive commercial information processing environment in which a relatively high level of document security, operational accountability, and information assurance are required. The typical information processed in this environment is trade secret, mission critical, or subject to legal and regulatory considerations, such as for privacy or governance. This environment is not intended to support life-critical or national… read more security applications. This environment will be known as "Operational Environment A." read less

This standard defines the application layer with TCP/IP providing functions in the transport and Internet layers to enable utility management of the end user energy environment, including demand response, load control, time of day pricing, management of distributed generation, electric vehicles, etc. Depending on the physical layer in use (e.g., IEEE 802.15.4™, IEEE 802.11™, IEEE 1901™, IEEE 1901.2™), a variety of lower layer protocols may be involved in providing a complete solution. Generally,… read more lower layer protocols are not discussed in this standard except where there is direct interaction with the application protocol. This standard defines the mechanisms for exchanging application messages, the exact messages exchanged including error messages, and the security features used to protect the application messages. With respect to the Open Systems Interconnection (OSI) network model, this standard is built using the four layer Internet stack model. The defined application profile sources elements from many existing standards, including IEC 61968 and IEC 61850, and follows a RESTful architecture (Fielding [B3]) using IETF protocols such as HTTP. read less

This standard defines an application profile that provides an interface between the smart grid and users. It enables management of the end user energy environment, including demand response, load control, price communication, distributed generation, energy storage, and electric vehicles, as well as the support of additional commodities, including water, natural gas, and steam. This standard defines the mechanisms for exchanging application messages, the exact messages exchanged including error… read more messages, and the security features used to protect the application messages. This standard focuses on a variety of possible architectures and usage models, including direct communications between a service provider and consumers/prosumers, communications within a premises network, and communications between a service provider and an aggregator. Lastly, this standard sources elements from many existing standards, including IEC 619686 and IEC 61850, and follows a RESTful architecture utilizing widely adopted protocols such as TCP/IP and HTTP. In addition, it supports all of the needs of IEEE Std 1547™-2018. This revision maintains backward compatibility with IEEE Std 2030.5™-2018, except for elimination of the requirements for mandatory DERControl modes, while providing an expanded feature set. read less

Profile S of the IEEE 896.X series will address the subset of 896.1 to be adopted as well as electrical, mechanical packaging, environmental, and other considerations Current backplane protocol standards do not address the unique requirements associated with spaceborne processing systems. This standard will establish and specify the requirements (bus, mechanical and electrical) to support implementation of spaceborne Futurebus+ based processing systems.required for spaceflight. This profile… read more will leverage heavily the work ongoing in the 896.5 Military Profile, the 896.9 Fault Tolerance Working Group, and the 896.8 Desktop Profile. read less
