To build the fifth generation (5G) mobile network, the sharing structure in the 5G network adopted in industries has gained great research interesting. However, in this structure data are shared among diversity networks, which introduces the threaten of network security, such as covert timing channels. To eliminate the covert timing channel, we propose to inject noise into the covert timing channel. By analyzing the modulation method of covert timing channels, we design the jamming strategy on the covert channel. According to the strategy, the interference algorithm of the covert timing channel is designed. Since the interference algorithm depends heavily on the memory, we construct a distributing jammer. Experiments results show that these covert time channel can be blocked under the distributing jammer.

Firstly, this paper analyses the technical foundation of single sign-on solution of unified authentication platform, and analyses the advantages and disadvantages of each solution. Secondly, from the point of view of software engineering, such as function requirement, performance requirement, development mode, architecture scheme, technology development framework and system configuration environment of the unified authentication platform, the unified authentication platform is analyzed and designed, and the database design and system design framework of the system are put forward according to the system requirements. Thirdly, the idea and technology of unified authentication platform based on JA-SIG CAS are discussed, and the design and implementation of each module of unified authentication platform based on JA-SIG CAS are analyzed, which has been applied in ship cluster platform.

The Internet of Things (IoT) increasingly demonstrates its role in smart services, such as smart home, smart grid, smart transportation, etc. However, due to lack of standards among different vendors, existing networked IoT devices (NoTs) can hardly provide enough security. Moreover, it is impractical to apply advanced cryptographic solutions to many NoTs due to limited computing capability and power supply. Inspired by recent advances in IoT demand, in this paper, we develop an IoT security architecture that can protect NoTs in different IoT scenarios. Specifically, the security architecture consists of an auditing module and two network-level security controllers. The auditing module is designed to have a stand-alone intrusion detection system for threat detection in a NoT network cluster. The two network-level security controllers are designed to provide security services from either network resource management or cryptographic schemes regardless of the NoT security capability. We also demonstrate the proposed IoT security architecture with a network based one-hop confidentiality scheme and a cryptography-based secure link mechanism.
