We describe JVer, a tool for verifying Java bytecode programs annotated with pre and post conditions in the style of Hoare and Dijkstra. JVer is similar to ESC/Java [1], except that: (1) it produces verification conditions for Java bytecode, not Java source; (2) it is sound, because it makes conservative assumptions about aliasing and heap modification; (3) it produces verification conditions d...

While most approaches in formal methods address system correctness, ensuring robustness has remained a challenge. In this paper we present and study the logic rLTL which provides means to formally reason about both correctness design. Furthermore, identify large fragment of for verification problem can be efficiently solved, i.e., done by using an automaton, recognizing behaviors described form...

In his paper [9], Stadler develops techniques for improving the security of existing secret sharing protocols by allowing to check whether the secret shares given out by the dealer are valid. In particular, the secret sharing is executed over abelian groups. In this paper we develop similar methods over non-abelian groups.

Recent work on distributed aggregation has assumed a benign population of participants. In modern distributed systems, it is now necessary to account for adversarial behavior. In this paper we consider the problem of ensuring verifiable yet efficient results to typical aggregation queries in a distributed, multi-party setting. We describe a general framework for the problem, including the threa...

We present a simple and fast method for conducting end to end voting and allowing public verification of correctness of the announced vote tallying results. In the present note voter privacy protection is achieved by use of a simple form of distributing the tallying of votes and creation of a verifiable proof of correctness amongst several servers, combined with random representations of intege...

The misinterpretation and misuse of p-value have been increasing for decades. In March 2016, the American Statistical Association released a statement to warn about the use and interpretation of p-value. In this study, we provided a definition and discussion of p-value and emphasized the importance of its accurate interpretation.    

In some German-language contributions to the debate on free will, it is assumed or claimed that determinism not an empirically verifiable thesis. Peter Bieri, for example, thinks one must presuppose in order understand world as a conceivable world. Determinism would then be empirical thesis, but rather condition without which conceivability of cannot thought (Bieri 2001, 15/16). Geert Keil writ...
