"Insight into the financial benefits of education choices would be invaluable to students trying to navigate the modern marketplace of higher education, allowing them to make much more informed choices. Privacy-preserving technologies that enable computing on data while encrypted is far and away the best way to provide these insights while also protecting the privacy of US citizens."...
After Equifax breach, how worried should you be about your personal information?
Computer Science Professor at the New Jersey Institute of Technology Kurt Rohloff said it’s more than just a small inconvenience. “I would say it definitely pays off in the long run. It’s definitely what I’d be doing if I were in that situation,” he said. Rohloff is also the co-founder and director of NJIT’s Cybersecurity Research Center. When asked if breaches are taking place more often or is it more often that we’re hearing about them, he replied, “Probably both.”...
OPM breach a failure on encryption, detection
Not all experts agree. Kurt Rohloff, associate professor at the New Jersey Institute of Technology and director of the NJIT Cybersecurity Center questioned the claim that legacy systems can't support encryption. "The statement that legacy systems cannot encrypt may not be completely true," Rohloff said. "It may be very expensive to integrate encryption technologies with legacy systems but it is generally possible."...

Fully Homomorphic Encryption Research
Alfred P. Sloan Foundation $509,038
2017 Fully Homomorphic Encryption (FHE) allows researchers to analyze encrypted data accurately without decrypting those data. It is an intriguing method for providing access to sensitive datasets while respecting both privacy concerns and licensing agreements and may eventually have significant use in privacy-protecting research protocols. This grant funds a project to demonstrate the usefulness of FHE algorithms in academic research.

Why Encryption Holds the Secret to Data SecurityTDWI Upside
Mathematically transforming information into something indistinguishable from gibberish, encryption guarantees that only approved users can reverse the transformation. The transformation's mathematical complexity underpins encryption's robust security.
A Scalable Implementation of Fully Homomorphic Encryption Built on NTRUInternational Conference on Financial Cryptography and Data Security
Kurt Rohloff, David Bruce Cousins
2014 In this paper we report on our work to design, implement and evaluate a Fully Homomorphic Encryption (FHE) scheme. Our FHE scheme is an NTRU-like cryptosystem, with additional support for efficient key switching and modulus reduction operations to reduce the frequency of bootstrapping operations. Ciphertexts in our scheme are represented as matrices of 64-bit integers. The basis of our design is a layered software services stack to provide high-level FHE operations supported by lower-level lattice-based primitive implementations running on a computing substrate. We implement and evaluate our FHE scheme to run on a commodity CPU-based computing environment. We implemented our FHE scheme to run in a compiled C environment and use parallelism to take advantage of multi-core processors. We provide experimental results which show that our FHE implementation provides at least an order of magnitude improvement in runtime as compared to recent publicly known evaluation results of other FHE software implementations.
An update on SIPHER (scalable implementation of primitives for homomorphic encryption)—FPGA implementation using SimulinkIEEE Conference on High Performance Extreme Computing (HPEC)
David Bruce Cousins, Kurt Rohloff, Chris Peikert, Rick Schantz
2012 Accelerating the development of a practical Fully Homomorphic Encryption (FHE) scheme is the goal of the DARPA PROCEED program. For the past year, this program has had as its focus the acceleration of various aspects of the FHE concept toward practical implementation and use. FHE would be a game-changing technology to enable secure, general computation on encrypted data, e.g., on untrusted off-site hardware. However, FHE will still require several orders of magnitude improvement in computation before it will be practical for widespread use. Recent theoretical breakthroughs demonstrated the existence of FHE schemes, and to date much progress has been made in both algorithmic and implementation improvements. Specifically our contribution to the Proceed program has been the development of FPGA based hardware primitives to accelerate the computation on encrypted data using FHE based on lattice techniques. Our project, SIPHER, has been using a state of the art tool-chain developed by Mathworks to implement VHDL code for FPGA circuits directly from Simulink models. Our baseline Homomorphic Encryption prototypes are developed directly in Matlab using the fixed point toolbox to perform the required integer arithmetic. Constant improvements in algorithms require us to be able to quickly implement them in a high level language such as Matlab. We reported on our initial results at HPEC 2011. In the past year, increases in algorithm complexity have introduced several new design requirements for our FPGA implementation. This report presents new Simulink primitives that had to be developed to deal with these new requirements.
