    • Protecting Computer Systems through Eliminating Vulnerabilities 

      Lee, Byoungyoung (Georgia Institute of Technology, 2016-01-29)
      Many system components and network applications are written in unsafe programming languages that are prone to memory corruption vulnerabilities. To combat countless catastrophes from these vulnerabilities, there have ...
    • Provably-Secure Approximate k-NN Search Protocol 

      Tang, Tianxin (Georgia Institute of Technology, 2021-03-26)
      This talk examines the problem of privacy-preserving approximate kNN search in an outsourced environment — the client sends the encrypted data to an untrusted server and later can perform secure approximate kNN search and ...
    • Proving Anything Quickly, Privately, and Elegantly with Secure Computation 

      Kolesnikov, Vladimir (Georgia Institute of Technology, 2018-08-24)
      Secure multi-party computation (MPC) is an area of cryptography which studies computing on encrypted data. In this talk, I will discuss a somewhat surprising MPC technique of proving statements in zero-knowledge (i.e., ...
    • RAIN: Refinable Attack Investigation with On-demand Inter-process Information Flow Tracking 

      Ji, Yang (Georgia Institute of Technology, 2018-04-18)
      As modern attacks become more stealthy and persistent, detecting or preventing them at their early stages becomes virtually impossible. Instead, an attack investigation or provenance system aims to continuously monitor and ...
    • Recent Insights from Analysis of Users' Web Browsing Behavior 

      Lut, Yuliia (Georgia Institute of Technology, 2021-02-26)
      Accurately analyzing and modeling online browsing behavior plays a key role in understanding users and technology interactions. Specifically, understanding whether users have correct perceptions of their browsing behavior ...
    • Reflections on Internet Surveillance 

      Weaver, Nicholas (Georgia Institute of Technology, 2020-03-27)
      Six years ago Edward Snowden leaked a massive trove of internal NSA documents detailing the operation of the US government’s electronic surveillance system. The overall systems described a wide-ranging approach of remarkably ...
    • Revocations Are Dead, Long Live Revocations 

      Levin, David (Georgia Institute of Technology, 2018-01-12)
      The importance of the web’s public key infrastructure (PKI) cannot be overstated: it is what allows users to know with whom they are communicating online. Central to its correct operation is the ability to “revoke” ...
    • RFDIDS: Radio Frequency-based Distributed Intrusion Detection System for the Power Grid 

      Shekari, Tohid (Georgia Institute of Technology, 2019-04-19)
      Recently, the number of cyber threats to power systems has increased at an unprecedented rate. For instance, the widespread blackout in Ukrainian power grid on December 2015 was a wakeup call that modern power systems have ...
    • rtCaptcha 

      Uzun, Erkam (Georgia Institute of Technology, 2018-04-12)
      More organizations are turning to facial and voice recognition, or other biometric identifiers, to authenticate users and grant access to their systems. In particular, some services (e.g. Mastercard Identity Check) allow ...
    • rtCaptcha: A Real-Time CAPTCHA Based Liveness Detection System 

      Uzun, Erkam (Georgia Institute of Technology, 2018-03-02)
      Facial/voice-based authentication is becoming increasingly popular (e.g., already adopted by MasterCard and AliPay), because it is easy to use. In particular, users can now authenticate themselves to online services by ...
    • The Scalability of Vulnerability Analysis 

      Bittick, Kennon (Georgia Institute of Technology, 2018-01-26)
      Analyzing software for vulnerabilities is an important capability in ensuring the security of a computing system. As software has become more complex and ubiquitous, however, traditional vulnerability analysis techniques ...
    • Secure Communication Channel Establishment: TLS 1.3 (Over TCP Fast Open) vs. QUIC 

      Boldyreva, Alexandra (Georgia Institute of Technology, 2019-11-01)
      Secure channel establishment protocols such as TLS are some of the most important cryptographic protocols, enabling the encryption of Internet traffic. Reducing the latency (the number of interactions between parties) in ...
    • Secure Data Outsourcing: Access Pattern Confidentiality in Outsourced Databases 

      Degitz, Alexander (Georgia Institute of Technology, 2017-01-13)
      When sensitive data is outsourced to an untrustworthy cloud storage provider, encryption techniques can be used to enforce data confidentiality. Ideally, such encryption techniques should not only enforce the confidentiality ...
    • Securing Democracy in the Fourth Industrial Revolution 

      Anastasopoulos, Lefteris J. (Georgia Institute of Technology, 2021-01-15)
      In this talk, I discuss research which focuses on designing systems needed to secure democracy and democratic political institutions, such as elections, in the interconnected digital world of the “fourth industrial revolution.”
    • Securing FPGA-Accelerated Cloud Infrastructures 

      Szefer, Jakub (Georgia Institute of Technology, 2020-11-13)
