Recent advances in computing such as the massively parallel GPUs (Graphical Processing Units),coupled with the need to store and deliver large quantities of digital data especially images, has brought a number of challenges for Computer Scientists, the research community and other stakeholders. These challenges, such as prohibitively large costs to(More)
Small embedded devices such as microcontrollers have been widely used for identification, authentication, securing and storing confidential information. In all these applications, the security and privacy of the microcontrollers are of crucial importance. To provide strong security to protect data, these devices depend on cryptographic algorithms to ensure(More)
A wide variety of cryptographic embedded devices including smartcards, ASICs and FPGAs must be secure against breaking in. However, these devices are vulnerable to side channel attacks. A side channel attack uses physical attributes such as differences in the power consumption measured from the physical implementation of the cryptosystem while it is(More)
In Computer Science Education, teaching of computer programming (CP) for beginners remains one of the greatest challenges. This is due to the nature of first year students characterized by under-preparedness, poor academic background and so on. Moreover, the traditional lecture-based approach is used and the computer laboratories are rarely used.(More)
The challenge in performance of Next Generation Networks (NGNs) is a growing concern. Bandwidth limitation for multimedia applications in NGNs such as voice and video telephony along with the increasing number of applications on the Internet, service classification and efficient resource management have all become quite challenging tasks. In order to(More)
Police impersonation is a serious crime against the state and is on the rise globally. One reason why it is easily accomplished is the lack of strong security features on police equipment. Police impersonation could place the citizens in a state of insecurity and upsurge social anxiety. Moreover, it could tarnish the image of the police and reduce their(More)
