“…But, this solution is not the optimized solution as further delay trade off will come into play. Delay can be further reduced by using advanced software scheme which is used to manage the switching of receiver in wireless communication application (Stecklina et al, 2014). Low duty cycle protocols (LDCPs) can be used for efficiently implementations.…”

Wireless sensor nodes consume lots of energy during communication but huge power consumption has been observed during active listening in idle mode as source nodes can start data transmission at any time. Power saving can be achieved by establishing synchronization among end nodes. Many rendezvous solutions are available and out of which wake up receiver found extremely adroit. A non volatile wake up transceiver has been proposed in the present paper that works on the basis of ID matching. State of art using 4GB of memory to remember states of sensor nodes while proposed technique used only 60 bits of memory with very less false alarm probability. Power consumption for proposed model is only 59.47 nW. Hence this model is quite effective in terms of power consumption and memory usage as compared to trailing models.

In this paper we present the architectural design of the tiny scale very long instruction word (VLIW) soft-core processor TinyVLIW8. The processor is designed to achieve a minimal instruction execution time and design size. Although, the instruction repertoire is not large, it is adequate for control tasks, which require decision making that could not easily be implemented in an application specific integrated circuit (ASIC) and in which an extensive mathematical processing is not required. Especially in the area of embedded control tasks with real-time requirements an architecture using singlecycle instructions is key. We will illustrate an application of our TinyVLIW8 by presenting an design of a secure wake-up receiver for low power wireless sensor nodes. To the best of our knowledge, the presented soft-core processor is the smallest VLIW design with an average instruction execution time of one clock cycle only. The core consumes less than 6 % of the logic cells of the smallest Altera Cyclone IV FPGA and can be used in a system-on-chip design as well.

“…During the project we developed a secure wake-up scheme based on the time-based one-time password (TOTP) algorithm. The work was presented on the International Workshop on Mobile Systems and Sensor Networks for Collaboration in 2014 [SKM14]. I used this application within my Ph.D. thesis as an example of a secured TSS.…”

“…But wireless wake-up receivers are vulnerable against depletion attacks in which a wake-up signal is sent repeatedly to deplete the mote's power supply. For the prevention of a simple replay of a wake-up sequence we implemented a SWUR that extends a common wake-up receiver with a security module that features a modified TOTP algorithm [SKM14,MMPR11]. The system is illustrated in Figure 2.6.…”

With the introduction of the Internet at the end of the last century the modern society was fundamentally changed. Computer systems became an element of nearly all parts of our daily live. Due to the interconnection of these systems local borders are mostly vanished, so that information is accessible and exchangeable anywhere and at anytime. But this increased connectivity causes that physical fences are not longer an adequate protection for computer systems. Whereas the security of commodity computer systems was improved continuously and similarly with their increased connectivity, deeply embedded systems were then and now mostly protected by physical fences. But the ubiquitous availability of embedded systems in personal and commercial environments makes these systems likewise accessible and moves them strongly into the focus of security investigations. Deeply embedded systems are usually equipped with tiny scale micro controllers, which are limited in their available resources and do not feature secure mechanisms to isolate system resources. Hence, a single error in a local software component is not limited to the component itself, instead the complete system may be influenced. The lack of resource isolation makes tiny scale systems prone for accidental errors but in particular vulnerable for a broad variety of malicious software. For a safe and secure operation of computer systems it is strongly recommended that software components are isolated in such a manner that they have access only to those resources, which are assigned to them. Even though a substantial number of approaches in the context of embedded system's safety were investigated during the last fifteen years, security was mostly neglected. This thesis is focused on security aspects where malicious software wittingly tries to bypass available protection mechanisms. The thesis introduces a security platform for tiny scale systems that enforces an isolation of software components considering security aspects. Due to the limited resources of tiny scale systems the proposed solution is based on a co-design process that takes the static and predefined nature of deeply embedded systems into account and includes hardware, compile-time, and run-time partitions to reduce the number of additional run-time components, to avoid performance drawbacks, and to minimize the memory as well as the components footprint overhead. To prove the applicability of the presented platform it was applied and evaluated with two real applications.In addition, an investigation of technologies of commodity computer systems that are suitable to build secure systems is presented. The thesis analyzes their enforcement based on the features provided by the introduced security platform. The contributions of this thesis include an enforcement of a security isolation of system resources on tiny scale systems and enable the development of a broad variety of secure tiny scale system applications.
