Abstract:
Systems and techniques are provided for per-device authentication. A hardware serial number associated with a hardware component of a computing device may be received. The hardware serial number may be converted to a hardware key check. A hardware key associated with a certificate from the computing device may be received. The hardware key may be compared to the hardware check key to obtain a verification of the certificate. The certificate may be verified when the hardware key check matches the hardware key and the certificate may not be verified when the hardware key check does not match the hardware key. A signature associated with the certificate may be verified. Access to the data processing apparatus by the computing device may be permitted when the certificate is verified and the signature is determined to be authentic.

Claim (Index 9):
A device comprising:\n one or more processors; a network interface that receives, from a first computing device, a first digital certificate, and receives, from a third computing device, a second digital certificate, wherein the first digital certificate includes a first hardware key and a digital signature, wherein the first hardware key was generated based on a hardware serial number associated with a hardware component of a third computing device, the hardware component of the third computing device being a particular type of hardware component, wherein the second digital signature includes a second hardware key and the digital signature, and wherein the second hardware key was generated based on a hardware serial number associated with a hardware component of a fourth computing device, the hardware component of the fourth computing device being of the particular type of hardware component; and a computer-readable storage media that stores code executable by the one or more processors to:\n generate, based on a hardware serial number associated with a hardware component of the first computing device, a first hardware key check, the hardware component of the first computing device being of the particular type of hardware component; \n determine whether the first digital certificate is valid based on a comparison of the first hardware key and the first hardware key check; \n responsive to determining that the first digital certificate is valid, permit the first computing device to access the device; \n generate, based on the hardware serial number associated with a hardware component of the second computing device, a second hardware key check, the hardware component of the second computing device being of the particular type of hardware component; \n determine whether the second digital certificate is valid based on a comparison of the second hardware key and the second hardware key check; and \n responsive to determining that the second digital certificate is valid, permit the second computing device to access the device.
