Experience with Practical Formal Verification at an Industrial Scale

Reasoning about High-Level Constructs in Hardware/Software Formal Verification

By making use of asymptotic properties of nonoscillatory solutions the oscillation behavior of solutions for the integro-dynamic equation x(t) = e(t) − ∫ t 0 k(t, s)f(s, x(s))∆s, t ≥ 0 and the integral equation x(t) = e(t) − ∫ t 0 k(t, s)f(s, x(s))∆s, t ≥ 0 on time-scales are investigated. Easily verifiable sufficient conditions are established for the oscillation of all solutions. The results ...

Several verifiable sufficient conditions for regularity and singularity of interval matrices are given. As an application, a verifiable sufficient condition is derived for an interval matrix to have all eigenvalues real.

We show how to combine the individual verification mechanism of Selene with the coercion-resistant e-voting scheme from Juels, Catalano and Jakobsson (JCJ). This results in an e-voting scheme which allows the voter to check directly that her vote is counted as intended, but still allows her to mitigate coercion. We also construct variants of the protocol which provide everlasting privacy or bet...
