A Performance Comparison Of Data Encryption Algorithms, Aamer Nadeem, Dr. M. Younus Javed
International Conference on Information and Communication Technologies
The principal goal guiding the design of any encryption algorithm must be security against unauthorized attacks. However, for all practical applications, performance and the cost of implementation are also important concerns. A data encryption algorithm would not be of much use if it is secure enough but slow in performance because it is a common practice to embed encryption algorithms in other applications such as e-commerce, banking, and online transaction processing applications. Embedding of encryption algorithms in other applications also precludes a hardware implementation, and is thus a major cause of degraded overall performance of the system. In this paper, …

International Conference on Information and Communication Technologies
Software system may have various nonfunctional requirements such as reliability, security, performance and schedulability. If we can predict how well the system will meet such requirements at an early phase of software development, we can significantly save the total development cost and time. Among non-functional requirements, reliability is commonly required as the essential property of the system being developed. Therefore, many analysis methods have been proposed but methods that can be practically performed in the design phase are rare. In this paper we show how design-level aspects can be used to separate reliability concerns from essential functional concerns during software …
