This thesis evaluates techniques for improving the performance of three architecturally different web servers. We study strategies for effectively accepting incoming connections under conditions of high load. The experimental evaluation shows that the method used to accept new connection requests can significantly impact server performance. By modifying each server’s accept strategy, we improve...

Abstract Who bears the consequences of administrative problems in healthcare? We use data on repeated interactions between a large sample U.S. physicians and many different insurers to document complexity healthcare billing, estimate its economic costs for doctors patients. Observing back-and-forth sequences claim denials resubmissions past visits, we can physicians’ haggling with collect payme...

For portable communication systems, the delegation-based authentication protocol provides efficient subsequent login authentication, data confidentiality, user privacy protection, and non-repudiation. However, in all proposed protocols, the non-repudiation of mobile users is based on an unreasonable assumption that home location registers are always trusted. To weaken this assumption and enhanc...

Digital signatures provide authentication and non-repudiation in a public way in the sense that anyone can verify the validity of a digital signature using the corresponding public key. In this paper, we consider the issues of (1) signature privacy and (2) the corresponding public provability of signature. We propose a new digital signature variant, secret signature, which provides authenticati...

This paper proposes an extended mobile payment service model founded on the existing ones to solve the non-repudiation problems with fair non-repudiation protocols for all phases in a typical m-commerce transaction. The novel model bases on assumptions about the cooperation between mobile network operators and financial institutions to deal with different payment amounts ranging from micro to m...
