Patent number: 11934458Abstract: A binary code similarity detection system that compares a target binary code to a source code by comparing the target binary code to a comparing binary generated by compiling the source code. Rather than using a comparing binary generated using a random or fixed compiling configuration, the system identifies the compiling configuration of the target binary code and compares the target binary code to a comparing binary generated using the same compiling configuration as the target binary code. The compiling configuration of the target binary code may be identified by a neural network (e.g., a graph attention network trained on attributed function call graphs of binary codes with known compiling configurations). The target binary code and the comparing binary may be compared using a graph neural network (e.g., a graph triplet loss network) that compares attributed control flow graphs of the of the target binary code and the comparing binary.Type: GrantFiled: May 21, 2021Date of Patent: March 19, 2024Assignee: The George Washington UniversityInventors: Yuede Ji, Hao Howie Huang

Patent number: 11922136Abstract: An integrated photonics computing system implements a residue number system (RNS) to achieve orders of magnitude improvements in computational speed per watt over the current state-of-the-art. RNS and nanophotonics have a natural affinity where most operations can be achieved as spatial routing using electrically controlled directional coupler switches, thereby giving rise to an innovative processing-in-network (PIN) paradigm. The system provides a path for attojoule-per-bit efficient and fast electro-optic switching devices, and uses them to develop optical compute engines based on residue arithmetic leading to multi-purpose nanophotonic computing.Type: GrantFiled: February 25, 2019Date of Patent: March 5, 2024Assignee: The George Washington UniversityInventors: Jiaxin Peng, Tarek El-Ghazawi, Volker J.

Patent number: 11861049Abstract: A system and method for defense against cache timing channel attacks using cache management hardware is provided. Sensitive information leakage is a growing security concern exacerbated by shared hardware structures in computer processors. Recent studies have shown how adversaries can exploit cache timing channel attacks to exfiltrate secret information. To effectively guard computing systems against such attacks, embodiments disclosed herein provide practical defense techniques that are readily deployable and introduce only minimal performance overhead. In this regard, a new protection framework against cache timing channel attacks is provided herein by leveraging commercial off-the-shelf (COTS) hardware support in processor caches, including last level caches (LLC), for cache monitoring and partitioning. This framework applies signal processing techniques on per-domain cache occupancy data to identify suspicious application contexts.Type: GrantFiled: January 28, 2020Date of Patent: January 2, 2024Assignee: The George Washington UniversityInventors: Guru Prasadh V.

Patent number: 11615328Abstract: Effective management of cloud computing service levels (e.g. availability, performance, security) and financial risk is dependent on the cloud service provider's (CSP's) capability and trustworthiness. The invention applies industry cloud service level agreements (SLAs) with statistical and machine learning models for assessing CSPs and cloud services, and predicting performance and compliance against service levels. Cloud SLAs (ISO/IEC, EC, ENISA), cloud security requirements and compliance (CSA CCM, CAIQ), along with CSP performance (SLAs, cloud services) are analyzed via Graph Theory analysis and MCDA AHP to calculate CSP trustworthiness levels. CSP trustworthiness levels are input with CSP SLA content, cloud service performance measurements and configuration parameters into machine learning Regression analysis models to predict CSP cloud service performance and cloud SLA compliance, and enable model analysis and comparison.Type: GrantFiled: April 13, 2020Date of Patent: March 28, 2023Assignee: The George Washington UniversityInventor: Robert Maeser
