Timing Channels in Cryptography

This book deals with timing attacks on cryptographic ciphers. It describes and analyzes various unintended covert timing channels that are formed when ciphers are executed in microprocessors. The book considers modern superscalar microprocessors which are enabled with features such as multi-threaded, pipelined, parallel, speculative, and out-of order execution. Various timing attack algorithms are described and analyzed for both block ciphers as well as public-key ciphers. The interplay between the cipher implementation, the system architecture, and the attack's success is analyzed. Further hardware and software countermeasures are discussed with the aim of illustrating methods to build systems that can protect against these attacks.

Discusses various timing attack algorithms in detail allowing readers to reconstruct the attack Presents the application of timing attacks on remote systems and cloud environments Examines information leakage models that would help quantify leakage in a covert timing channel Includes supplementary material: sn.pub/extras

This book deals with timing attacks on software implementations of encryption algorithms. It describes and analyzes various unintended covert timing channels that are formed when ciphers are executed in microprocessors. Modern superscalar microprocessors are considered, which are enabled with features such as multi-threaded, pipelined, parallel, speculative, and out-of-order execution. Various timing attack algorithms are described and analyzed for block ciphers as well as public-key ciphers. The interplay between the cipher implementation, system architecture, and the attack's success is analyzed. Further hardware and software countermeasures are discussed with the aim of illustrating methods to build systems that can protect against these attacks.Discusses various timing attack algorithms in detail allowing readers to reconstruct the attack.Provides several experimental results to support the theoretical analysis provided in the book.Analyzes information leakage from cache memories and branch prediction units in the processor.Examines information leakage models that would help quantify leakage in a covert timing channels.
