Connecting a virtual token to a physical token
First Claim
Patent Images
1. A method comprising receiving a certification message generated by a physical token of a computing device that attests to a public key associated with a virtual token of the computing device and the physical token;
- and requesting an entity to issue a credential for the public key associated with the virtual token based upon the certification message.

8. A physical token for a computing device, comprising
a register to record an integrity metric that measures a virtual token of the computing device, and one or more processing units to generate a random number and a certification message that specifies the register, that is encrypted by a key of an entity, and that has uniqueness based upon the random number.

13. A computing device comprising
a virtual token to record integrity metrics; -
a physical token to record an integrity metric that measures the virtual token, and to generate a certification message that attests to the integrity metric, that is encrypted by an asymmetric key of an entity, and that has uniqueness; and
a processor to request the entity to issue a credential for an asymmetric key associated with the virtual token based upon the certification message. - View Dependent Claims (14, 15, 16)

17. A computing device comprising
a physical token to generate a certification message that attests to an operating environment of the computing device and a credential issued to the physical token; - and
a virtual machine monitor comprising a virtual token to further attest to the operating environment, wherein the virtual machine monitor requests the physical token to provide the certification message, causes the certification message to be transferred to an entity, and receives a credential for the virtual token in response to transferring the certification message to the entity. - View Dependent Claims (18, 19, 20, 21)

22. A method comprising
receiving a request for a credential to be issued to a virtual token of a computing device; -
determining whether the virtual token satisfies criteria for a suitable virtual token based upon information of the request; and
issuing the credential to the virtual token of the computing device in response to determining that the virtual token satisfies the criteria. - View Dependent Claims (23, 24, 25)

26. A machine readable medium comprising instructions, which in response to being executed, result in a computing device
generating a certification message that attests to a physical token and an operating environment of a computing device; - and
requesting that an entity issue a credential to a virtual token of the computing device based upon the certification message. - View Dependent Claims (27, 28, 29, 30)
