Abstract
Systems, devices, and methods for device or bio-organism authenticity verification are provided. A method can include identifying (i) respective challenges indicating respective stimuli and (ii) a root node hash value, generating the respective stimuli, recording respective responses to the respective electrical stimuli, hashing the respective responses resulting in respective hashed responses, hashing a combination of hashed responses of the respective hashed responses resulting in a key, and comparing the key to the root node hash value.
Claims20
A method for validating an identity of an electronic device or a bio-organism, the method comprising:
- identifying (i) respective challenges indicating respective electrical stimuli to provide to respective components of the electronic device or bio-organism and (ii) a pre-computed root node hash value determined based on providing the electrical stimuli to the electronic device or the bio-organism previously;
- generating the respective electrical stimuli incident on the respective components of the electronic device or bio-organism;
- recording respective electrical responses elicited by the components of the electronic device or the bio-organism responsive to the respective electrical stimuli;
- hashing the respective electrical responses resulting in respective hashed responses;
- combining respective hashed responses associated with components of a same assembly resulting in combinations of hashed responses;
- hashing the combinations of hashed responses resulting in assembly hashes;
- combining the assembly hashes resulting in a system hash;
- hashing the system hash resulting in a key;
- and
- validating the identity of the electronic device or the bio-organism by comparing the key to the root node hash value.
A system for validating an identity of an electronic device or bio-organism, the system comprising:
- a test device configured to:
- identify (i) respective challenges indicating respective electrical stimuli to provide to respective components of the electronic device or bio-organism and (ii) a pre-computed root node hash value determined based on providing the electrical stimuli to the electronic device or the bio-organism previously;
- generate the respective electrical stimuli incident on the respective components of the electronic device or bio-organism;
- and
- record respective electrical responses elicited by the components of the electronic device or the bio-organism responsive to the respective electrical stimuli;
- and
- a hash operator configured to:
- hash the respective electrical responses resulting in respective hashed responses;
- combine respective hashed responses associated with components of a same assembly resulting in combinations of hashed responses;
- hash the combinations of hashed responses resulting in assembly hashes;
- combine the assembly hashes resulting in a system hash;
- and
- hash the system hash resulting in a key;
- and
- the test device is further configured to validate the identity of the electronic device or the bio-organism by comparing the key to the root node hash value.
A non-transitory machine-readable medium including instructions that, when executed by a machine, configure the machine to perform operations for validating an identity of an electronic device or a bio-organism, the operations comprising:
- identifying (i) respective challenges indicating respective electrical stimuli to provide to respective components of the electronic device or bio-organism and (ii) a pre-computed root node hash value determined based on providing the electrical stimuli to the electronic device or the bio-organism previously;
- generating the respective electrical stimuli incident on the respective components of the electronic device or bio-organism;
- recording respective electrical responses elicited by the components of the electronic device or the bio-organism responsive to the respective electrical stimuli;
- hashing the respective electrical responses resulting in respective hashed responses;
- combining respective hashed responses associated with components of a same assembly resulting in combinations of hashed responses;
- hashing the combinations of hashed responses resulting in assembly hashes;
- combining the assembly hashes resulting in a system hash;
- hashing the system hash resulting in a key;
- and
- validating the identity of the electronic device or the bio-organism by comparing the key to the root node hash value.
