Secure wireless charging

摘要

An embodiment includes a method executed by at least one processor of a member computing node comprising: establishing a communication channel with a verifier computing node, the member computing node and the verifier computing node each coupled to a respective charging coil; determining a group of devices approved for charging with the verifier computing node; determining the member computing node is a member of the group of devices; authenticating the member computing node to the verifier computing node; in response to authenticating the member computing node to the verifier computing node, inductively charging the member computing node based on a magnetic field produced by the verifier computing node. Other embodiments are described herein.

1. At least one storage medium having instructions stored thereon for causing a system to:
cause a member computing node to:
establish a communication channel with a verifier computing node, the member computing node and the verifier computing node each coupled to a respective charging coil;determine a group of devices approved for charging with the verifier computing node;determine the member computing node is a member of the group of devices;anonymously authenticate the member computing node to the verifier computing node;in response to anonymously authenticating the member computing node to the verifier computing node, inductively charge the member computing node based on a magnetic field produced by the verifier computing node; wherein: (a) the member computing node does not uniquely identify itself to the verifier computing node; (b) the anonymously authenticating the member computing node to the verifier computing node comprises the member computing node signing a message with a private key and communicating the signed message to the verifier computing node; and (c) the private key and a plurality of other private keys all correspond to a public key coupled to the verifier computing node.
