Assa Abloy had two patents in edge computing during Q1 2024. Assa Abloy AB has developed systems and methods for secure execution of functions for edge devices, involving a controller, a plurality of edge devices, and an array of secure elements. The edge devices gather data for applications, which is then processed by the secure elements under the control of the controller. Each secure element is assigned to a specific edge device for executing functions and communicating the results back to the respective edge device, ensuring secure data processing.

Application: Secure element arrays in internet-of-things systems (Patent ID: US20240022389A1)
The patent filed by Assa Abloy AB describes systems and methods for ensuring secure execution of functions for edge devices. These systems involve a controller communicating with edge devices to receive data, which is then processed by an array of secure elements associated with specific edge devices. The controller then relays the results of the executed functions back to the respective edge devices. Additionally, the patent details a method for transmitting data using a collision-resistant full-duplex communication protocol over a half-duplex connection. This method involves ending data reception mode, transmitting data frames, monitoring for acknowledgments, determining the need for retransmission, and identifying device roles for efficient data transmission.
The described method is particularly useful in scenarios where a controller of a physical access control system communicates with readers over an RS-485 connection. The data frames transmitted include options, payload, and cyclic redundancy check fields, with retransmission triggered by a mismatch in the acknowledgment received. The patent also covers a non-transitory computer-readable medium containing executable program code that enables processors to carry out the steps outlined in the method for transmitting data. This technology ensures reliable and secure communication between devices in edge computing systems, enhancing overall system efficiency and data integrity.
