Mitigation of Targeted and Non-targeted Covert Attacks as a Timing Game
We consider a strategic game in which a defender wants to maintain control over a resource that is subject to both targeted and nontargeted covert attacks. Because the attacks are covert, the defender must choose to secure the resource in real time without knowing who controls it. Each move by the defender to secure the resource has a one-time cost and these defending moves are not covert, so t...
متن کاملKeyDrown: Eliminating Keystroke Timing Side-Channel Attacks
Besides cryptographic secrets, side-channel attacks also leak sensitive user input. The most accurate attacks exploit cache timings or interrupt information to monitor keystroke timings and subsequently infer typed words and sentences. Previously proposed countermeasures fail to prevent keystroke timing attacks as they do not protect keystroke processing among the entire software stack. We clos...
متن کاملAn Analysis of Covert Timing Channels
Covert channels have tmditionally been categorized as either stomge channels or timing channels[6, 71. This paper questions this categorization, and discwses channels that cannot be clearly identified as either stomge or timing channels, but have aspects of both. A new model of timing channels is presented, which allows for channels that have chamcteristics of both stomge channels and timing ch...
متن کاملA Review on Covert Timing Channels & their Applications
Covert network timing channels control time between transmissions of packets in overt network communication and transmits hidden messages. This paper presents an overview of different concepts of covert timing channels such as types, features and properties. There is range of terms used for security of information such as encryption, covert channels, network steganography or information hiding ...
