The project investigates the problem of communication security in the mobile environment where both confidentiality and authenticity are of prime concern. Stream ciphers are a very natural choice in mobile environment as they provide an efficient cryptographic protection using a limited computing resources. We model stream cipher as a system of multivariate equations. In this approach, security of stream ciphers can be measured as the complexity of an algorithm that solves the appropriate system of equations.

The project investigates communication security in the mobile environment where both confidentiality and authenticity are of a prime concern. Stream ciphers are a natural choice in mobile environments as they provide an efficient cryptographic protection using a limited computing resources. We treat stream ciphers as algebraic objects whose properties fully determine their cryptographic strength. We first analyse existing stream ciphers showing their algebraic properties and later we derive a design methodology for provably secure stream ciphers. The project leads to new secure and efficient designs for stream ciphers that are the preferred cryptographic tools used in Australian industry.Read moreRead less

Algebraic Analysis of Cryptosystems. This project studies an (new) algebraic approach to cryptanalysis of modern block ciphers. The approach works for all cryptosystems that use either small S-boxes, or their algebraic structure can be described by a system of overdefined quadratic equations. The cryptosystems that are potentially breakable using this approach are Rijndael and Serpent - the two top finalists of the Advanced Encryption Standard contest. The project also explores how this approach ....Algebraic Analysis of Cryptosystems. This project studies an (new) algebraic approach to cryptanalysis of modern block ciphers.

Current Internet only supports limited quality of service (QoS) within isolated domains. This project allows critical applications to be deployed over the global Internet. The project employs a programmable architecture for composing services and intelligent software elements for negotiating acceptable QoS responses for individual application flows over multiple administrative domains. The architecture employs DiffServ's aggregation property to make it scalable for the Internet core. Successful outcomes would open the floodgates, allowing the development and deployment of applications such as high quality videoconferences, live sport broadcasts, remote medical services, network games, real-time on-line educations, and multimedia distributions.

Fair Intelligent Quality of Service Control and Path Discovery Mechanisms for Internet Scalable Architectures. Until now the Internet only provides best effort service without guaranteeing the timeliness or actual delivery of data. Quality of Service (QoS) architectures have been proposed but not deployed due to a fundamental problem: either the architecture is not scalable or it does not guarantee end-to-end QoS. The project tackles the problem by introducing mechanisms for network path discove ....Fair Intelligent Quality of Service Control and Path Discovery Mechanisms for Internet Scalable Architectures. Until now the Internet only provides best effort service without guaranteeing the timeliness or actual delivery of data. Quality of Service (QoS) architectures have been proposed but not deployed due to a fundamental problem: either the architecture is not scalable or it does not guarantee end-to-end QoS. The project tackles the problem by introducing mechanisms for network path discovery in the network core. The solution allows an integration of both scalability and end-to-end QoS architectures. The outcomes allow network providers to provision network resources efficiently, to develop competitive Internet-based products; and the service providers to develop quality services such as high quality IP phone, multimedia distributions.
