Abstract: This research proposes a secure transmission and authentication protocol named deep Q Net_Key updation (DQN_KeyUp) in the internet of things (IoT) for providing security to medical data. Here, multiple entities, like as IoT user, IoT Server, and IoT data provider are used and security is provided using processes, such as authentication, data transmission, verification, and dynamic key updation. Moreover, user verification is established using a finger vein-based biometric modality. In addition to this, the proposed DQN_KeyUp uses security operations, like encryption, hashing, secret keys, Kronecker product, and session passwords, wherein the secret key is generated using the deep Q network (DQN). The assessment of the DQN_KeyUp based on computational time, validation time, and memory shows that the DQN_KeyUp is effective in attaining minimal values of computational time of 0.067 S, validation time of 0.155 S, and memory of 0.154 MB.

Keywords: internet of things; IoT; device-to-device communication; authentication; dynamic key updation; deep Q network; DQN.
