SEMI E132: Specification for Equipment Client Authentication and Authorization
This standard mandates how EDA data consumers/clients can obtain data from the equipment, addressing issues with simultaneous, multi-client requests for data and overall information security. The equipment can grant access control rights to specific clients, who can then establish an authenticated communication session and request data from the tool or perform interface discovery. The standard includes detailed scenarios, attributes, and states models required to support EDA client access.
This standard is part of the collection of standards that make up an EDA (Equipment Data Acquisition) or “Interface A” implementation. EDA is an alternate channel that equipment can use to publish data to any EDA data consumer/client such as the factory host, without using the SECS/GEM (SEMI E5 and SEMI E30) messaging infrastructure.
A number of our products support SEMI E132.
