Design and implementation of an open security architecture for a software-based security module
Kaynar, Kaan; Özgit, Attila; Department of Computer Engineering (2009)
Main purpose of this thesis work is to design a comprehensive and open security architecture whose desired parts could be realized on a general-purpose embedded computer without any special cryptography hardware. The architecture provides security mechanisms that implement known cryptography techniques, operations of some famous network security protocols and appropriate system security methods. Consequently, a server machine may offload a substantial part of its security processing tasks to an embedded com...
Clock synchronization algorithms on a software defined can controller: implementation and evaluation
Yalçın, Serkan; Werner Schmidt, Klaus.; Department of Electrical and Electronics Engineering (2020)
Many advanced driver-assistance systems (ADAS) and in-vehicle applications require coordination for their safety-critical tasks. To achieve such a coordination, different electronic control units (ECUs) in the system should synchronize their clocks in order to share a global time. Although the controller area network (CAN) is the most widely used communication bus for the information exchange among ECUs, it does not support the required clock synchronization. Moreover, even several advanced clock synchroniz...
Statistical inference based load balanced routing in software defined networks
Kaya, Semih; Koçyiğit, Altan; Department of Information Systems (2020-10-14)
Networks have been the main method of transferring data for more than forty years. The traffic volumes and sizes of networks have increased considerably in the last two decades. The traditional methods used in the networks to transfer data become inefficient due to this growth. Therefore, network planning and smart delivery methods have gained importance. Accordingly, traffic engineering methods are deployed to meet the faster and more efficient delivery requirements. These methods have been proven ben...
An Ad Hoc networking testbed using software-defined radios
Tabrizi, Negin; Onur, Ertan; Department of Computer Engineering (2019)
For establishing communication infrastructures in the aftermath of man-made or natural disasters, ad hoc networking architectures seem to be more adequate. There are various simulators for studying ad hoc networks. However, simulators cannot accurately model all the factors of the physical environment. By using a test-bed, the significant gap between simulations and real-life implementations can be reduced. In this work, an ad hoc indoor testbed has been developed using software-defined radios (SDR). By usi...
A low latency, high throughput and scalable hardware architecture for flow tables in software defined networks
Eral, Göksan; Schmidt, Şenan Ece; Department of Electrical and Electronics Engineering (2016)
Software Defined Networking (SDN) is a new paradigm which requires multi-field packet classification for each received packet by looking up Flow Tables which contain a large number of rules and corresponding actions. The rules are defined by upto 15 packet header fields including IP source and destination address. If more than one rule rule matches then the action of the highest priority rule is executed. Furthermore rules with wildcard fields are possible. The SDN Flow Table should scale with the rule coun...
