Abstract This document discusses the threats to protocols used to carry authentication for network access. The security requirements arising from these threats will be used as additional input to the Protocol for Carrying Au...

We extend the range of security policies that can be guaranteed with proof carrying code from the classical type safety, control safety, memory safety, and space/time guarantees to more general security policies, such as general resource and access control. We do so by means of (1) a specification logic for security policies, which is the pasttime fragment of LTL, and (2) a synthesis algorithm ...

In this paper the authors consider the continuous deterministic, infinite horizon, single item inventory system within the setting of a retailer sector in which the demand rate for an item is time dependent. The parameter of the replenishment cost is kept constant, but the carrying cost per unit is allowed to vary. The optimal policies are found, and decision rules and classical EOQ model have ...

For extensible software platforms in safety-critical domains, it is important that deployed plug-ins work as specified. This is especially true with the prospect of allowing third parties to add plug-ins. We propose a contract-based approach for deployment-time verification. Every plug-in guarantees its functional behavior under a specific set of assumptions towards its environment. With proof-...

Currently there are no Internet access authentication protocols available that are lightweight, can be carried over arbitrary access networks, and are flexible enough to be used in all the likely future ubiquitous mobility access contexts. This article proposes the PANA/GSM authentication protocol for heterogeneous network access as a step towards filling this gap. A security analysis of the PA...

This document specifies Protocol for carrying Authentication for Network Access (PANA) Relay Element functionality, which enables PANA messaging between a PANA Client (PaC) and a PANA Authentication Agent (PAA) where the two nodes cannot reach each other by means of regular IP routing. Information about the current status of this document, any errata, and how to provide feedback on it may be ob...

We introduce a generic framework for proof carrying code, developed and mechanically verified in Isabelle/HOL. The framework defines and proves sound a verification condition generator with minimal assumptions on the underlying programming language, safety policy, and safety logic. We demonstrate its usability for prototyping proof carrying code systems by instantiating it to a simple assembly ...

At present, most of the control methods of the lower extremity exoskeleton carrying robot require to calculate the system’s dynamic equation and create the control quantity at each moment, which don’t make full use of the repeatability feature of human movement and inevitably causes the delay on the dynamic response of the system. In this paper, utilizing the dynamic repeat characteristics of h...
