Distributed Denial of Service (DDoS) attacks serve to diminish the ability of the network to perform its intended function over time. The paper presents the design, implementation and analysis of a protocol based upon a technique for address agility called DDoS Resistant Multicast (DRM). After describing the our architecture and implementation we show an analysis that quantifies the overhead on network performance. We then present the Simple Agile RPL multiCAST (SARCAST), an Internet-of-Things routing protocol for DDoS protection. We have implemented and evaluated SARCAST in a working IoT operating system and testbed. Our results show that SARCAST provides very high levels of protection against DDoS attacks with virtually no impact on overall performance.

File encryption is an effective way for an enterprise to prevent its data from being lost. However, the data may still be deliberately or inadvertently leaked out by the insiders or customers. When the sensitive data are leaked, it often results in huge monetary damages and credit loss. In this paper, we propose a novel group file encryption/decryption method, named the Group File Encryption Method using Dynamic System Environment Key (GEMS for short), which provides users with auto crypt, authentication, authorization, and auditing security schemes by utilizing a group key and a system environment key. In the GEMS, the important parameters are hidden and stored in different devices to avoid them from being cracked easily. Besides, it can resist known-key and eavesdropping attacks to achieve a very high security level, which is practically useful in securing an enterprise's and a government's private data.
 

Demand response management (DRM) is one of the main features in smart grid, which is realized via communications between power providers and consumers. Due to the vulnerabilities of communication channels, communication is not perfect in practice and will be threatened by jamming attack. In this paper, we consider jamming attack in the wireless communication for smart grid. Firstly, the DRM performance degradation introduced by unreliable communication is fully studied. Secondly, a regret matching based anti-jamming algorithm is proposed to enhance the performance of communication and DRM. Finally, numerical results are presented to illustrate the impacts of unreliable communication on DRM and the performance of the proposed anti-jamming algorithm.
