Developing new lines of defense in cybersecurity

Sony, Target, Facebook, U.S. Central Command — all have  been victims of high-profile hacks. But these are just the tip of the iceberg.

President Obama has put the estimated global cost of cybercrime and economic espionage at $1 trillion annually — which is why researchers at NJIT’s College of Computing Sciences and elsewhere are accelerating efforts to combat the threats.

Before joining NJIT, Associate Professor Kurt Rohloff worked in the defense industry supporting DARPA research.  He is continuing this work at NJIT as director of NJIT’s CryptoLab, where he’s developing and applying practical methods for a new family of encryption schemes called Fully Homomorphic Encryption (FHE). In simplest terms, the technology enables encrypted data to be passed to and processed by a third party, such as a cloud host, without ever being decrypted. This will enable privacy-sensitive enterprises like healthcare and financial services to cut costs by confidently outsourcing large parts of their IT infrastructure.

In the area of remote sensing, NJIT Associate Professor Guiling Wang and her colleagues are working on ways not only to encrypt data but also to detect whether the data collected by sensors — for example, from a battlefield — has been altered or replaced by misleading “disinformation.”
