TVAL+ : TVLA and Value Analyses Together

Leak Me If You Can: Does TVLA Reveal Success Rate?

Test Vector Leakage Assessment Methodology (TVLA) has emerged as a popular side-channel testing methodology as it can detect the presence of side-channel information in leakage measurements. However, in its current form, TVLA results cannot be used to quantify side-channel vulnerability. In this paper, we extend the TVLA testing beyond its current scope. Precisely, we derive concrete relationsh...

TVLA: A System for Implementing Static Analyses

Compactly Representing First-Order Structures for Static Analysis

A fundamental bottleneck in applying sophisticated static analyses to large programs is the space consumed by abstract program states. This is particularly true when analyzing programs that make extensive use of heap-allocated data. The TVLA (Three-Valued Logic Analysis) program analysis and verification system models dynamic allocation precisely by representing program states as first-order st...

TVLA: A system for generating abstract interpreters

The course will present TVLA (Three-Valued-Logic Analyzer). TVLA is a ”‘YACC’”’-like framework for automatically constructing abstract interpreters from an operational semantics. The operational semantics is specified as a generic transition system based on first order logic. TVLA has been implemented in Java and was successfully used to prove interesting properties of (concurrent) Java program...

What Lies Ahead: Extending TVLA Testing Methodology Towards Success Rate

Evaluation of side channel vulnerability of a cryptosystem has seen significant advancement in recent years. Researchers have proposed several metrics like Test Vector Leakage Assessment Methodology (TVLA), Normalized Inter Class Variance (NICV), Signal to Noise Ratio (SNR), Guessing Entropy to determine side channel security of cryptoimplementations. Among these, TVLA has emerged as the front-...
