A Security Infrastructure for Mobile Transactional Systems
نویسندگان
چکیده
In this paper, we present an infrastructure for providing secure transactional support for mobile databases. Our infrastructure protects against external threats — malicious actions by nodes not authorized to access the data. The major contribution of this paper, however, is to classify and present algorithms to protect against internal security threats. Internal threats are malicious actions by authenticated nodes that misrepresent protocol specific information. We quantify the cost of our security mechanisms in context of Deno: a system that supports object replication in a transactional framework for mobile and weakly-connected environments.

A New Intrusion Detection System to deal with Black Hole Attacks in Mobile Ad Hoc Networks
By extending wireless networks and because of their different nature, some attacks appear in these networks which did not exist in wired networks. Security is a serious challenge for actual implementation in wireless networks. Due to lack of the fixed infrastructure and also because of security holes in routing protocols in mobile ad hoc networks, these networks are not protected against attack...
متن کاملA survey on impact of cloud computing security challenges on NFV infrastructure and risks mitigation solutions
Increased broadband data rate for end users and the cost of resource provisioning to an agreed SLA in telecom service providers, are forcing operators in order to adhere to employment Virtual Network Functions (VNF) in an NFV solution. The newly 5G mobile telecom technology is also based on NFV and Software Define Network (SDN) which inherit opportunities and threats of such constructs. Thus a ...
متن کاملSupport for Recovery in Mobile Systems
Mobile systems increasingly are being used for production-grade datacentered applications which require system support for transactional properties. For mobile applications, transactions can hide, to some extent, the infrastructure intrinsic to mobile systems, such as disconnection from the network, dozing, and storage limitations. In this paper, we introduce a framework to understand, specify,...
متن کاملA Security Scheme for Mobile Agent Platforms in Large-Scale Systems
Mobile agents have recently started being deployed in largescale distributed systems. However, this new technology brings some security concerns of its own. In this work, we propose a security scheme for protecting mobile agent platforms in large-scale systems. This scheme comprises a mutual authentication protocol for the platforms involved, a mobile agent authenticator, and a method for gener...
