As the network-on-chip (NoC) integrated into an SoC design can come from an untrusted third party, there is a growing risk that data integrity and security get compromised when supposedly sensitive data flows through such an untrusted NoC. We thus introduce a new method that can ensure secure and secret data transmission over such an untrusted NoC. Essentially, the proposed scheme relies on encoding binary data as delays between packets travelling across the source and destination pair. The maximum data transmission rate of this inter-packet-delay (IPD)-based communication channel can be determined from the analytical model developed in this article. To further improve the undetectability and robustness of the proposed data transmission scheme, a new block coding method and communication protocol are also proposed. Experimental results show that the proposed IPD-based method can achieve a packet error rate (PER) of as low as 0.3% and an effective throughput of 2.3 x 10(5) b/s, outperforming the methods of thermal covert channel, cache covert channel, and circuit-based encryption and, thus, is suitable for secure data transmission in unsecure systems.

In this study, we present our findings with regard to teaching basic programming concepts at an Open Access Institution. The goal was to gather insight into how to best introduce programming to our students. We found that our students should start with block coding, as a means to slowly and easily introduce coding concepts. Then they are ready for text-based programming skills. This flow allows them to understand and be able to apply basic computing concepts and enjoy the process of learning. Also, introducing block coding should be done via a fun game or activity to entice them to want to learn programming.

This paper is devoted to a transform-based quantitative data compression technique involving rapid enumeration in a unary-binary time-based numeral system (NS). The symbols comprising the alphabets of human-computer interaction languages (HCIL), which are used in an informational message (IM), are collected in primary code tables, such as the ASCII table. The statistical-oriented data compression method using unconventional timer encryption and encoding information are proposed by us. It was constructed probability - discrete model of the set of character sequences and characterized some probabilistic algorithms associated with the recovery of text by its public key and its cipher. We find the possibility of parallel implementation of this method by building a block of timer tags. The necessary complex assessments are made. The method can be used to compress SMS messages. Probabilistic-statistical analysis and evaluation of their effectiveness are obtained.

A Parity-Check Spectral R-Code

引用

Computational Mathematics and Modeling 2018年第2期29卷 228-232页

作者： Gurov, S.I. Faculty of Computational Mathematics and Cybernetics Moscow State University Moscow Russian Federation

This article introduces a parity-check code based on the Rademacher function. The error-correction model of the code corresponds to a binary symmetrical channel: bits may be inverted randomly and independently, but no bit insertion/bit omission occurs. The code corrects a single error;its redundancy and coding/decoding features are virtually identical with those of the Hamming code, but it has clear advantages for application of redundant coding in fault-tolerant integrated-circuit design. © 2018, Springer Science+Business Media, LLC, part of Springer Nature.

We are proposing a workshop that instructs the audience on how to develop fun and engaging projects involving different technologies. These types of projects can be used by faculty to introduce programming skills in the classroom, but they are also a fantastic resource for outreach activities. Students can create these projects as a way to develop and promote their technical skills. Presenters will also share best practices and allow for discussion in creating and then conducting these projects at their institution.

The primary goal of this project is to educate our audience about algorithms. We used Sphero, a fun and engaging robot sphere, to pique the interest of our participants with the intent of promoting STEM and Information Technology. By participating in our workshops, our audience experimented with *** and block coding, which allowed them to learn about algorithms through easily replicable examples. This project showed our workshop participants that programming can be fun. The workshop results proved that the audience had an increased interest in programming.

This paper shows how a novel infrastructure which makes use of the multiple antennas available on IEEE 802.11n Access Points can be combined with block erasure coding to multicast video with no packet loss. This paper also shows that this can be obtained while maintaining an efficient code rate, which is better than 1) packet repetition on the new infrastructure, 2) block erasure coding on the legacy infrastructure and 3) Leader-Based Protocols used on the legacy infrastructure. This study employs physical layer data rates of 52Mbps, 58.5Mbps and 65Mbps. Hence the infrastructure proposed solves also the "Performance Anomaly Problem" which results with legacy multicast that transmits the data using the most robust modulation and coding scheme.

COMPARISON OF ERASURE-AND-ERROR THRESHOLD DEcoding SCHEMES

IEICE TRANSACTIONS ON FUNDAMENTALS OF ELECTRONICS COMMUNICATIONS AND COMPUTER SCIENCES 1993年第5期E76A卷 820-827页

作者： HASHIMOTO, T Univ of Electro-communications Chofu Japan

Erasure-and-error decoding is a general form of channel decoding and is a basis of important coding schemes, such as the concatenated coding scheme and coded ARQ. However, there do not exist enough discussions on the interrelationship between erasure-and-error decoding schemes. In this paper, threshold decoding schemes are discussed in a systematic manner and compared with Forney's optimal scheme. Some confusions in known results are pointed out and new results on threshold decoding are shown.

Dimensional Scalable Lossless Compression of MRI Images Using Haar Wavelet Lifting Scheme with EBCOT

INTERNATIONAL JOURNAL OF IMAGING SYSTEMS AND TECHNOLOGY 2014年第2期24卷 175-181页

作者： Anusuya, V. Raghavan, V. Srinivasa PSR Engn Coll Sivakasi Tamil Nadu India Loyola Inst Technol Madras Tamil Nadu India

Modern medical imaging requires storage of large quantities of digitized clinical data. To provide high bandwidth and to reduce the storage space, a medical image must be compressed before transmission. One of the best image compression techniques is using the Haar wavelet transform. The method of discrete cosine transform (DCT) is chosen to be the preprocessing scheme to identify the image frequency information and has excellent energy compaction property. The block coding algorithm uses a wavelet transform to generate the sub band samples, which can be quantized and coded. It is more robust to errors than many other wavelet-based schemes. In this article, simulations are carried out on different medical Images and it demonstrates the performance in terms of peak signal to noise ratio (PSNR) & bits per pixel (BPP). Our proposed method is found to preserve information fidelity while reducing the amount of data. (c) 2014 Wiley Periodicals, Inc. Int J Imaging Syst Technol, 24, 175-181, 2014
