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

An information handling system of an internet of things sensor hub comprising:

• a network interface adapter to:
• receive one or more first remotely generated random-string numbers from a provisioning server for generation of a first time limited, one-time use password generated by a one-time password algorithm;
• wherein the first remotely generated random-string numbers are also transmitted to an internet of things sensor device in communication with the internet of things sensor hub;
• and
• receive a first sensor data record from and encrypted by the internet of things sensor device;
• a processor executing code instructions to:
• generate the first time limited, one-time use password using the received one or more first remotely generated random-string numbers;
• generate a first session key by mapping the first time limited, one-time use password to data of a fixed size according to a preset function;
• decrypt the first sensor data record using the session key;
• and
• if the decryption is successful, evaluate the decrypted first sensor data record.

An information handling system of an encryption key seed provisioning server comprising:

• a network interface adapter executing code instructions to:
• transmit 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 device and a remotely connected internet of things sensor hub;
• a processor executing code instructions to:
• associate the internet of things sensor device 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 device and internet of things sensor hub with the one or more first locally generated random-string numbers in the table.
