Description

Research Topic Description, including Problem Statement:

The concern and need to protect data and privacy continue to grow. Over the years, fully homomorphic encryption (FHE) has emerged as a possible solution and offers defense mechanisms that allows computations to be performed directly on encrypted data while maintaining confidentiality. However, high computational complexity on large ciphertexts had limited the capability for FHE to be leveraged. To address these challenges, there is a need for cryptographic accelerators that can expedite real-world application deployment. Thus, the objective of this project is to design and optimize the homomorphic encryption algorithm to enhance data sharing and confidentiality. To accomplish the research objective, there is a need to develop a framework that leverages the benefits of homomorphic encryption (HE), and machine learning (ML), to protect information during data collection and sharing process against potential attacks such as data collected from supervised devices such as sensors, network flow, and camera systems that are encrypted using HE schemes. Machine learning (ML) as a cloud-based service is growing rapidly and the growth of Internet-of-Things data have given rise to a significant concern for monitoring systems while maintaining the security of data during ML inferences. Cryptographic accelerators may reduce the computational burden of homomorphic functions, enabling faster and more efficient computations on the encrypted data. The proposed approach will advance new theories and methods for effective and efficient defense processes involving homomorphic encryption, ML, and optimization of data sharing and privacy. 

Additionally, how can the IC or other groups with sensitive data work (e.g., DoD, personal medical data, census data) with the data and perform advanced analyses while the data is in a protected state (i.e., encrypted). Current methods can have unacceptably large overheads and are clumsy to program, at best with their current tools working at what amounts to a gate level of programming. It is often difficult to specify security requirements (i.e., who gets to see what data) at a fine-grained level. 

Example Approaches: 

(1) Develop a software architecture for integrating FHE into networks to collect data from devices such as sensors and sensing and camera systems. (2) Provide a proof-of concept by developing a small data base using the software architecture. (3) Implement the software design using simulated or real sensor arrays feeding FHE data to an encrypted data base where ML operations will be executed. (4) Deliver a report that compares the results to the same data created in an unencrypted environment and demonstrates essential equivalence of the machine learning process and outcomes. (5) prepare a user-friendly set of tools and rules to apply homomorphic encryption to the problem of machine learning and privacy preservation. (6) Explore how the FHE will perform at scale with large datasets/changing of resources and demand on the system.

Also, current techniques fully homomorphic encryption currently applies for the underlying encrypted operations, but these need to be combined with boutique programming languages and associated compilers, along with development of “data independent algorithms”. In addition, advanced security sensitive programming languages might be able to use specially developed type systems to specify data security requirements in a fine-grained way.

Relevance to the Intelligence Community:
