Proof-Carrying Code
, 1997
"... This paper describes proof-carrying code (PCC), a mechanism by which a host system can determine with certainty that it is safe to execute a program supplied (possibly in binary form) by an untrusted source. For this to be possible, the untrusted code producer must supply with the code a safety proo ..."

proof that attests to the code's adherence to a previously defined safety policy. The host can then easily and quickly validate the proof without using cryptography and without consulting any external agents. In order to gain preliminary experience with PCC, we have performed several case studies
Proofs that Yield Nothing but Their Validity or All Languages in NP Have Zero-Knowledge Proof Systems
- JOURNAL OF THE ACM
, 1991
"... In this paper the generality and wide applicability of Zero-knowledge proofs, a notion introduced by Goldwasser, Micali, and Rackoff is demonstrated. These are probabilistic and interactive proofs that, for the members of a language, efficiently demonstrate membership in the language without convey ..."

Safe Kernel Extensions Without Run-Time Checking
- Proc. of OSDI'96
"... Abstract This paper describes a mechanism by which an operating system kernel can determine with certainty that it is safe to execute a binary supplied by an untrusted source. The kernel first defines a safety policy and makes it public. Then, using this policy, an application can provide binaries i ..."

in a special form called proof-carrying code, or simply PCC. Each PCC binary contains, in addition to the native code, a formal proof that the code obeys the safety policy. The kernel can easily validate the proof without using cryptography and without consulting any external trusted entities
Trading Group Theory for Randomness
, 1985
"... In a previous paper [BS] we proved, using the elements of the Clwory of nilyotenf yroupu, that some of the /undamcn-la1 computational problems in mat & proup, belong to NP. These problems were also ahown to belong to CONP, assuming an unproven hypofhedi.9 concerning finilc simple Q ’ oup,. The a ..."

Constructivism and Proof Theory
, 2003
"... Introduction to the constructive point of view in the foundations of mathematics, in
particular intuitionism due to L.E.J. Brouwer, constructive recursive mathematics
due to A.A. Markov, and Bishop’s constructive mathematics. The constructive interpretation
and formalization of logic is described. F ..."

principles which are valid for choice sequences are discussed.
The second half of the article deals with some aspects of proof theory, i.e.,
the study of formal proofs as combinatorial objects. Gentzen’s fundamental contributions
are outlined: his introduction of the so-called Gentzen systems which use
A Secure and Optimally Efficient Multi-Authority Election Scheme
, 1997
"... Abstract. In this paper we present a new multi-authority secret-ballot election scheme that guarantees privacy, universal verifiability, and robustness. It is the first scheme for which the performance is optimal in the sense that time and communication complexity is minimal both for the individual ..."

A formal analysis and taxonomy of task allocation in multi-robot systems
- INT’L. J. OF ROBOTICS RESEARCH
, 2004
"... Despite more than a decade of experimental work in multi-robot systems, important theoretical aspects of multi-robot coordination mechanisms have, to date, been largely untreated. To address this issue, we focus on the problem of multi-robot task allocation (MRTA). Most work on MRTA has been ad hoc ..."

With the goal of bringing objective grounding to this important area of research, we present a formal study of MRTA problems. A domain-independent taxonomy of MRTA
Translation Validation

Rather than proving in advance that the compiler always produces a target code which correctly implements the source code (compiler verification), each individual transl ..."

Efficient Representation and Validation of Proofs

Our framework, which we call LF i , inherits from LF the capability to encode various logics in a natural way. In addition, the LF i framework allows proof representations without
