Although multi-interface multi-channel (MIMC) wireless networks have drawn much attention, they are susceptible to various attacks. This paper describes three new types of attacks against a variety of channel assignment protocols: utilization-based conflict attack, link break attack, and denial-of-data attack. These attacks exploit the vulnerabilities arising from the inherent properties of channel...
Although multi-channel wireless protocols are becoming predominant, security mechanisms of channel assignment are far from sufficient to protect the channel usage. In this paper, we discuss radio jamming attacks, ripple effect attacks and false information injection attacks in multi-interface and multi-channel wireless networks. We propose a security mechanism to secure channel management in multi-channel...
In a distributed system, the classic PGP and PKI techniques provide means to establish trust based on credentials. However, the credentials are not bound to integrity levels. Furthermore, the structure of certification authority (CA) is centralized, which is vulnerable to be the single point failure even if backups are present. In this paper, we propose a decentralized method to establish trust in...
