The SCADA (Supervisory Control And Data Acquisition) has become ubiquitous in industrial control systems. However, it may be exposed to cyber attack threats when it accesses the Internet. We propose a three-layer IDS (Intrusion Detection System) model, which integrates three main functions: access control, flow detection and password authentication. We use the reliability test system IEEE RTS-79 to evaluate the reliability. The experimental results provide insights into the establishment of the power SCADA system reliability enhancement strategies.

The Radio Frequency Identification (RFID), as one of the key technologies in sensing layer of the Internet of Things (IoT) framework, has increasingly been deployed in a wide variety of application domains. But the reliability of RFID is still a great concern. This article introduces the group management of RFID passwords method, come up with by YUICHI KOBAYASHI and other researchers, which aimed to reduce the risk of privacy disclosure. But for reason that the password and pass key in the method, which are set to protect the ID, doesn't change and the ID is transmitted directly in the unsafe channel, it causes serious vulnerabilities that may be used by resourceful adversary. Thus, we proposed an improved method by using the random number to encrypt the password and switching the password into the temporally valid information. Besides, the protocol encrypts the ID during to avoid the direct transmission situation significantly increases the reliability.
