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 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.
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 stimuli and (ii) a root node hash value;
- generate the respective stimuli;
- and
- record respective responses to the respective electrical stimuli;
- and
- a hash operator configured to:
- hash the respective responses resulting in respective hashed responses;
- and
- hash a combination of hashed responses of the respective hashed responses resulting in a key;
- and
- the test device is further configured to compare 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 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.
