Speech recognition (SR) is a technology that can improve accessibility to computer systems for people with physical disabilities or situation-introduced disabilities. The wide adoption of SR technology; however, is hampered by the difficulty in correcting system errors. HCI researchers have attempted to improve the error correction process by employing multi-modal or speech-based interfaces. Th...

A delay-laser-based reservoir computer (RC) usually has its processing speed limited by the transient response of laser dynamics. Here, we study a simple all-optical approach to enhancing introducing optical injection layer conventional RC that consists semiconductor with delay loop. Using injection, laser’s effectively accelerates due speeded carrier-photon resonance. In chaotic time-series pr...

system has very much importance because it will increase performance and accuracy. The fault injection method is used to find out the fault tolerance of a system. This method is valuable and attractive. In this paper fast FPGA based fault injector for memory unit is introduced. In previous FPGA based fault injection methods the response according to the fault injection is send to the observatio...

The concept of fail silent nodes greatly simpli es the design and safety proof of highly dependable fault tolerant computer systems The MAintainable Real Time System MARS is a computer system where the hardware operating system and application level error detec tion mechanisms are designed to ensure the fail silence of nodes with a high probability The goal of this paper is two fold First the e...

Here we present methods for injecting raw frames at Layer 1 from within upper-layer protocols by abuse of in-band signaling mechanisms common to most digital radio protocols. This packet piggy-backing technique allows attackers to hide malicious packets inside packets that are permitted on the network. When these carefully crafted Packets-in-Packets (PIPs) traverse a wireless network, a bit err...

Transient faults due to single and multiple bit-flips and permanent aging effects due to Bias Temperature Instability (BTI) and Hot Carrier Injection (HCI) gradually reduce chip reliability over time. Unfortunately, the increasingly stringent on-chip dark-silicon power constraints prohibit costly fault resilience solutions. Clearly, a viable approach is needed that can address both transientand...

Fault injection attacks alter the intended behavior of microcontrollers, compromising their security. These attacks can be mitigated using software countermeasures. A widely-used software-based solution to deflect fault attacks is instruction duplication and n-plication. We explore two main limitations with these approaches: first, we examine the effect of instruction duplication under fault at...

Over the last years, an increasing number of safety-critical tasks have been demanded to computer systems. In this paper, a software-based approach for developing safety-critical applications is analyzed. The technique is based on the introduction of additional executable assertions to check the correct execution of the program control flow. By applying the proposed technique, several benchmark...
