The mission of the Cyber Security Lab at Michigan State University is to design cryptographic algorithms and network security protocols for the next generation Internet, ad-hoc and sensor networks where power efficiency and security are of major concerns. Cyber Security Lab also works on secure digital copyright protection and management.
Wireless communication is widely used for critical information sharing and data transmission in both civilian and military communications. Security has become a great concern and an urgent issue. Development of novel wireless systems with built-in security is being viewed as a major approach in securing wireless networks. The goal of this research is to create virtual physical boundary for wireless networks analogous to its wired counterpart using cryptographic techniques so that the security for wireless networks can be treated the same way as wired networks.
Public-key digital certificate has been widely used in public-key infrastructure (PKI) to provide user authentication and key agreement. However, the public-key digital certificate itself cannot be used directly to provide user authentication since a digital certificate can be easily recorded and played back once it has been revealed to a verifier. The goal of this research is to develop innovative and secure user authentication techniques similar to the current passport-then-face-matching based two-factor authentication. These designs can be used in online applications to enforce access security.
Sensor networks are being widely used in many areas to handle sensitive information. Sensor nodes are often deployed in accessible areas that are vulnerable to physical attacks. The sensor nodes are very limited in their energy, computation, and communication capabilities. These new constraints pose new challenges on authentication, privacy, robustness to denial-of-service attacks, secure routing, and node capture. Our goal is to develop security services and protocols suitable for sensor applications from the initial development so that a strong and complete protection against illegal activities can be assured.
In this project, we already developed several cryptographic secure digital watermarking techniques in both spatial and frequency domain. The schemes can be used to provide digital media copyright protection.
