Abstract
A first computing device maintains multiple resource-specific asymmetric keypairs that are each uniquely associated with a different protected resource on the first device, including a first resource-specific asymmetric keypair that is uniquely associated with a first protected resource. The first device engages with a second device in an authentication flow based on the first resource-specific asymmetric keypair. The first device receives, from the second device, a public-key certificate that contains target-binding data that indicates a specified asymmetric keypair. The first device checks whether the specified asymmetric keypair matches the first resource-specific asymmetric keypair. If so, and assuming any other authentication conditions are also met, the first device authenticates the second device to the first resource-specific asymmetric keypair, and grants the second device access to the first protected resource.
