September 15, 2006 NSF awards Subbalakshmi a grant for cryptography research
The National Science Foundation’s Cyber Trust Program has awarded Stevens Professor K.P. (Suba) Subbalakshmi a grant to further her research on wireless network security, in particular, the fundamental trade-offs in wireless security, power consumption and error-resilient encryption code design. Subbalakshmi, an Assistant Professor in Stevens’ Electrical and Computer Engineering Department, is researching concepts from algebraic coding theory, cryptography, renewal/reward theory and stochastic modeling, among other areas, that will address these trade-offs in areas such as the design of error-correcting encryption systems, wireless link status and battery-power adaptive encryption. The practical aspects of her research include implementing and testing the theoretical results in battery-power constrained devices, which will have a profound effect on low-power wireless technology for secure communications.
Security in wireless networks is challenging due to unique environmental problems such as high-variable error rates in the links, limited bandwidth and the finite battery power of the end devices. The traditional solutions to these problems – encryption and error correction –compete for the same resources and if not designed well, can work at cross-purposes to each other.
