The mission of the Cyber Security Laboratory at Michigan State University is to design and develop crypto-graphic algorithms and network security protocols for the next generation Internet, wireless net-works, ad-hoc and sensor networks where power efficiency and security are of major concerns. The expertise of the Cyber Security Lab also includes secure digital copyright protection and management.  Cyber Security Lab has both hardware and software platforms for design and evaluation of the secure communication systems. Our research has been supported by National Science Foundation, Air Force Research Labs, and an industry partner.  Below is a list of some projects in the Cyber Security Lab.

Cost-Aware Computation Outsourcing

Cloud computing is the state-of-the-art distributed computing paradigm to remedy the limited resource availability on the end-user with the resource abundance in the cloud through computation outsourcing. However, the shared nature of the cloud makes user privacy and data security major impediments since the end-users will no longer have full control over their computing problems and data outputs. To address these issues, we develop cost-aware secure computing outsourcing schemes under a given cost constraints and security requirement. This outsourcing scheme can be applied to both linear and non-linear optimization, which gives mobile users to securely outsourcing computationally intensive operations.

Optimal Code Construction for Distributed Storage and High Capacity Data Storage

Distributed storage is a resilient approach to provide data security while ensuring data availability in cloud computing. This diagram provides a cost-aware design trade-off between data security and storage.  Our new design can improve the performance of the existing schemes for about 15% in data reliability and storage efficiency. 

Secure Access Gateway for Smart Home and Smart Grid

Smart grid/home is a key interface for electric power and home automation.  In fact, smart home is transforming the home to an intelligent organism, a living, breathing life form.  A physical architecture for the smart grid and smart home is given in the following figure.  A key component for smart grid/home is the Secure Access Gateway (SAG), which enables the home electronic device to be remotely con-trolled and operated.

In this project, we have developed an SAG platform.  The SAG platform has an Ethernet interface and also a ZigBee interface.  With the Ethernet interface, we can remotely access SAG from either an Android smartphone or a PC. While the ZigBee interface enables the SAG to securely communicate with and manage ZigBee ready home electronic devices.  For the SAG, we put special emphasize on the security protection and management.  We have developed both one-time login name and one-time cryptographic authentication schemes for SAG based on our own cryptographic algorithms. The unique design makes SAG secure from security attacks. We also developed software for Android smartphones.  The software enables us to securely remote connect to the SAG and the devices protected by the SAG through the ZigBee inter-face.
