A recently filed patent (Publication Number: US20230308868A1) describes a method for performing key management for multiple communication devices. The method involves establishing a secure connection between the communication devices and a key management service using different wireless communication technologies. The communication devices negotiate authentication information with the key management service to enable secure communication and data protection on the wireless communication technology they use.

In one embodiment, the communication devices and the key management service are provisioned with authentication material in a trusted environment. This authentication material is used to establish the secure connection between the devices and the service using symmetric and/or asymmetric cryptography.

The method also includes the use of a gateway communication device that negotiates second authentication information between other communication devices and the key management service. This second authentication information includes an authentication bundle for secure communication and data protection on the wireless communication technology.

The negotiation of authentication information involves various operations such as provisioning, decommissioning, and renewing communication and authentication keys by the key management service. These keys are used to ensure secure communication and data protection.

Additionally, the key management service can provision authentication information to communication infrastructure devices via a secure connection using a different communication technology. This allows the infrastructure devices to have access to the authentication bundle for secure communication and data protection.

The communication devices themselves utilize the authentication information to perform secure communication on the wireless communication technology they use.

The patent also describes a communication device that includes communication units and a processing unit. The communication units enable communication using a wireless communication technology, while the processing unit negotiates authentication information with the key management service.

Furthermore, the patent discusses a system that includes multiple communication devices, a key management service, and potentially a communication infrastructure device. The key management service communicates with the communication devices via secure connections and negotiates authentication information for secure communication and data protection. The system may also involve the use of a communication infrastructure device that receives authentication information from the key management service.

Overall, this patent presents a method and system for efficient key management in wireless communication devices, ensuring secure communication and data protection.
