Abstract: Generally discussed herein are devices, systems, and methods for binding with cryptographic key attestation. A method can include generating, by hardware of a device, a device public key and a device private key, based on the device private key, signing a first attestation resulting in a signed first attestation, the first attestation claiming the device private key originated from the hardware, based on the device public key and the signed first attestation, registering the device with a trusted authority, generating, by the hardware, a first application private key and a first application public key, and based on the device private key, signing a second attestation resulting in a signed second attestation, the second attestation claiming the first application private key originated from the hardware, and based on the first application public key and the signed second attestation, registering a first application of the device to a first server.
