Abstract: Embodiments discussed herein refer to systems, methods, and circuits for establishing EHF contactless communications links. The EHF contactless communication link may serve as an alternative to conventional board-to-board and device-to-device connectors. The link may be a low-latency protocol-transparent communication link capable of supporting a range of data rates. The link may be established through a close proximity coupling between devices, each including at least one EHF communication unit. Each EHF unit involved in establishing an EHF communication link may progress through a series of steps before data can be transferred between the devices. These steps may be controlled by one or more state machines that are being implemented in each EHF communication unit.

Abstract: A communication device employs a contactless secure communication interface to transmit and receive data with a computing device using close proximity extremely high frequency (EHF) communication.

Upon completion of the discovery mode operation, the devices enter a link-training operation mode and exchange capability information about the respective devices. During transport mode operation the communication device employs methods to manage access to data stored on the communication device by encrypting the data using one or a combination of training information or capability information as a basis for generating an encryption key.
