Security and privacy of network transmitted system in the Internet of Robotic Things

The interconnection between robotic devices network can be referred as the Internet of Robotic Things (IoRT). Each robot device is equipped with sensors and communication hardware for collecting and sharing data between each other to support many useful services. In order to provide an effective solution to tackle robotic application issues a fog computing network in the robotic network system is introduced. Thus, a number of services are provided to our live works by deploying IoRT network system. However, critical security and privacy challenges in the IoRT transmitting network system are still there. Therefore, we design a proxy re-signcryption (PRS) cryptography method based on proxy re-encryption technology. Based on the PRS method, we propose a security and privacy transmitting data (SPT) scheme to protect the IoRT transmitting network system. The SPT scheme prevents a malicious FN from forging a valid ciphertext, which simultaneously guarantees the confidentiality and integrity of the transmitted message. To show the high efficiency of the proposed PRS method in terms of security and privacy threats, security analysis is presented. In addition, the evaluation shows that the PRS method is compatible with high efficiency performance to ensuring the success of IoRT network applications.
