Method and apparatus for generation of a time-based one-time password for session encryption of sensor data gathered in low-performance and IOT environments
A system for a time-based one-time password security system operating at a provisioning server may comprise transmitting one or more first locally generated random-string numbers for generation of a first time-based one-time password to a remotely connected internet of things sensor and a remotely connected internet of things sensor hub. The system may also comprise executing code instructions to associate the internet of things sensor with a first client key in a table stored in a memory operatively connected to the processor, associate the internet of things sensor hub with a second client key in the table, and associate the internet of things sensor and internet of things sensor hub with the one or more first locally generated random-string numbers in the table. Further the first remotely generated random-string numbers may identify a first preset function for generation of a first session key used in encrypting and decrypting sensor data records.
