In the past decade, we observed the trend of technological advancement towards the field of portable electronics. As electronic devices shrink in size, constraints emerge in the form of limited power supply and area for the implementation of information security mechanisms. In this work, our goal is to produce a complete AES block cipher for data encryption and perform optimization in terms of power...
The paper presents a new design approach for AES SubBytes transformation (S-box) by using the Linear Feedback Shift Register (LFSR). In the past, composite field arithmetic (CFA) is commonly deployed as it effectively produces lightweight and pure combinational architecture. Unfortunately, the downside of this methodology is that the resultant circuitry is complex in nature, which leads to long critical...
This paper proposes an efficient and flexible nearest-neighbor-based learning and recognition system on a programmable chip. The nearest neighbor search (NNS), which is a common computational problem in pattern recognition, is to find the minimal distance among all distances between an unknown sample and the complete set of the often high-dimensional reference database. In this paper, a reference...
Active service discovery in 802.11 requires the WLAN clients to broadcast the probe request frame based on its' list of preferred networks while searching for Access Point (AP) prior to authentication and association. The Medium Access Control (MAC) address, a unique identifier allocated to a network interface, is embedded in the probe request frame. Coupling with his or her personally identifiable...
