Abstract
Techniques are disclosed for encrypting internet-of-things (IoT) data of an IoT network only once at its inception until its final consumption without intervening encryption/decryption stages/cycles. The present encrypt-decrypt-once design thus eliminates potential exposure of the IoT data in its plaintext form of a traditional approach employing intervening encryption/decryption cycles. The present design is also efficient and reduces the burden on IoT resources by eliminating the need for encrypting and decrypting the data multiple times. To accomplish these objectives, a number of schemes for device enrollment, authentication, key distribution, key derivation, encryption and encoding are disclosed. The devices employ authenticated encryption because it provides confidentiality, integrity, and authenticity assurances on the encrypted data. The final consumption of the IoT data may be at a designated gateway or a corporate system.
