Reviews work of Koetter et al. and Dimakis et al.
The former provides an algebraic framework for linear network coding. The latter reduces the so called repair problem to single-source multicast network-coding problem and shows that there is a tradeoff between amount of data stored in a distributed sturage system and amount of data transfer required to repair the system if a node(hard-drive) fails.

Hardware Implementations of RS Decoding Algorithm for Multi-Gb/s Communicatio...RSIS International
In this paper, we have designed the VLSI hardware for a novel RS decoding algorithm suitable for Multi-Gb/s Communication Systems. Through this paper we show that the performance benefit of the algorithm is truly witnessed when implemented in hardware thus avoiding the extra processing time of Fetch-Decode-Execute cycle of traditional microprocessor based computing systems. The new algorithm with less time complexity combined with its application specific hardware implementation makes it suitable for high speed real-time systems with hard timing constraints. The design is implemented as a digital hardware using VHDL

Elgamal signature for content distribution with network codingijwmn
Network coding is a slightly new forwarding technique which receives various applications in traditional
computer networks, wireless sensor networks and peer-to-peer systems. However, network coding is
inherently vulnerable to pollution attacks by malicious nodes in the network. If any fake node in the
network spreads polluted packets, the pollution of packets will spread quickly since the output of (even an)
honest node is corrupted if at least one of the incoming packets is corrupted. There have been adapted a
few ordinary signature schemes to network coding that allows nodes to check the validity of a packet
without decoding. In this paper, we propose a scheme uses ElGamal signature in network coding. Our
scheme makes use of the linearity property of the packets in a coded system, and allows nodes to check the
integrity of the packets received easily.
An Efficient FPGA Implementation of the Advanced Encryption Standard Algorithmijsrd.com
A proposed FPGA-based implementation of the Advanced Encryption Standard (AES) algorithm is presented in this paper. This implementation is compared with other works to show the efficiency. The design uses an iterative looping approach with block and key size of 128 bits, lookup table implementation of S -box. This gives low complexity architecture and easily achieves low latency as well as high throughput. Simulation results, performance results are presented and compared with previous reported designs.
In this paper, low linear architectures for analyzing the first two maximum or minimum values are of paramount importance in several uses, including iterative decoders. The min-sum giving out step is to that it produces only two diverse output magnitude values irrespective of the number of incoming bit-to check communication. These new micro-architecture structures would utilize the minimum number of comparators by exploiting the concept of survivors in the search. These would result in reduced number of comparisons and consequently reduced energy use. Multipliers are complex units and play an important role in finding the overall area, speed and power consumption of digital designs. By using the multiplier we can minimize the parameters like latency, complexity and power consumption. The decoding algorithms we propose generalize and unify the decoding schemes originally presented the product codes and those of low-density parity-check codes.

Design of Reversible Sequential Circuit Using Reversible Logic SynthesisVLSICS Design
Reversible logic is one of the most vital issue at present time and it has different areas for its application, those are low power CMOS, quantum computing, nanotechnology, cryptography, optical computing, DNA computing, digital signal processing (DSP), quantum dot cellular automata, communication, computer graphics. It is not possible to realize quantum computing without implementation of reversible logic. The main purposes of designing reversible logic are to decrease quantum cost, depth of the circuits and the number of garbage outputs. In this paper, we have proposed a new reversible gate. And we have designed RS flip flop and D flip flop by using our proposed gate and Peres gate. The proposed designs are better than the existing proposed ones in terms of number of reversible gates and garbage outputs. So, this realization is more efficient and less costly than other realizations.
Design and Implementation of an Embedded System for Software Defined RadioIJECEIAES
In this paper, developing high performance software for demanding real-time embed- ded systems is proposed. This software-based design will enable the software engineers and system architects in emerging technology areas like 5G Wireless and Software Defined Networking (SDN) to build their algorithms. An ADSP-21364 floating point SHARC Digital Signal Processor (DSP) running at 333 MHz is adopted as a platform for an embedded system. To evaluate the proposed embedded system, an implementation of frame, symbol and carrier phase synchronization is presented as an application. Its performance is investigated with an on line Quadrature Phase Shift keying (QPSK) receiver. Obtained results show that the designed software is implemented successfully based on the SHARC DSP which can utilized efficiently for such algorithms. In addition, it is proven that the proposed embedded system is pragmatic and capable of dealing with the memory constraints and critical time issue due to a long length interleaved coded data utilized for channel coding.
Reliability Improvement in Logic Circuit Stochastic ComputationWaqas Tariq
Defects and faults arise from physical imperfections and noise susceptibility of the analog circuit components used to create digital circuits resulting in computational errors. A probabilistic computational model is needed to quantify and analyze the effect of noisy signals on computational accuracy in digital circuits. This model computes the reliability of digital circuits meaning that the inputs and outputs and their implemented logic function need to be calculated probabilistically. The purpose of this paper is to present a new architecture for designing noise-tolerant digital circuits. The approach we propose is to use a class of single-input, single-output circuits called Reliability Enhancement Network Chain (RENC). A RENC is a concatenation of n simple logic circuits called Reliability Enhancement Network (REN). Each REN can increase the reliability of a digital circuit to a higher level. Reliability of the circuit can approach any desirable level when a RENC composed of a sufficient number of RENs is employed. Moreover, the proposed approach is applicable to the design of any logic circuit implemented with any logic technology.

Error Correcting Codes are required to have a reliable communication through a medium that has an
unacceptable bit error rate and low signal to noise ratio. In IEEE 802.15.6 2.4GHz Wireless Body Area
Network (WBAN), data gets corrupted during the transmission and reception due to noises and
interferences. Ultra low power operation is crucial to prolong the life of implantable devices. Hence simple
block codes like BCH (63, 51, 2) can be employed in the transceiver design of 802.15.6 Narrowband PHY.
In this paper, implementation of BCH (63, 51, t = 2) Encoder and Decoder using VHDL is discussed. The
incoming 51 bits are encoded into 63 bit code word using (63, 51) BCH encoder. It can detect and correct
up to 2 random errors. The design of an encoder is implemented using Linear Feed Back Shift Register
(LFSR) for polynomial division and the decoder design is based on syndrome calculator, inversion-less
Berlekamp-Massey algorithm (BMA) and Chien search algorithm. Synthesis and simulation were carried
out using Xilinx ISE 14.2 and ModelSim 10.1c. The codes are implemented over Virtex 4 FPGA device and
tested on DN8000K10PCIE Logic Emulation Board. To the best of our knowledge, it is the first time an
implementation of (63, 51) BCH encoder and decoder carried out.

Abstract
The main aim of this project is to generate the address generation circuitry of Deinterleaver used in the WiMAX transreceiver using
the Xilinx Field Programmable Gate Array(FPGA). The floor function associated with the implementation of FPGA is very difficult in

modulations like QPSK, 16-QAM and 64-QAM along with its code rates make our approach to be novel and high efficient.

Los computadores actuales, desde los sistemas on-chip de los móviles hasta los más potentes supercomputadores, son paralelos. La escala va desde los 8 cores de un móvil hasta los millones desplegados por los grandes superomputadores. La necesidad de hacer visible la memoria del sistema a cada uno de sus cores se resuelve, independientemente de la escala, interconectando todos los cores con el rendimiento adecuado a unos costes acotados. En los sistemas de menor escala (MPSoCs), la memoria se comparte usando redes on-chip que transportan líneas de cache y comandos de coherencia. Unos pocos MPSoCs se interconectan formando servidores que usan mecanismos para extender la coherencia y compartir memoria usando una arquitectura CC-NUMA. Decenas de estos servidores se apilan en un rack y un número de racks (hasta centenares) constituyen un datacenter o un supercomputador. La memoria global resultante no puede ser compartida, pero sus contenidos son transferibles mediante el envío de mensajes a través de la red de sistema. Por ello, las redes son sistemas críticos y básicos en las arquitecturas de memoria de los computadores de cualquier gama. En esta charla se ofrecerá una visión argumentada de las elecciones que hacen diferentes fabricantes para el despliegue de las redes on-chip y de sistema que interconectan los computadores actuales.
LinuxCon2009: 10Gbit/s Bi-Directional Routing on standard hardware running Linuxbrouer
This talk my 2009 updates on the progress of doing 10Gbit/s routing on standard hardware running Linux. The results are good, BUT to achieve these results, a lot of tuning is required of hardware queues, MSI interrupts and SMP affinity, together with some (now) submitted patches. I\'ll explain the concept of network hardware queues and why interrupt and SMP tuning is essential. I\'ll present results from different hardware both 10GbE netcards and CPUs (current CPUs under test is AMD phenom and Core i7). Many future challenges still exists, especially in the area of more easy tuning. A high knowledge level about the Linux kernel is required to follow all the details.

We determine achievable rate regions when there are multiple sources present via a 2-source (3,2,2) exact repair problem.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

21. Part 2- Outline
● Introduction
● The repair problem
● Reduction of repair problem to single source multicast network
● Family of single source multi-cast networks arising from the
reduction
● A lower bound on min-cuts(i.e. An upper bound on max-flow
and hence coding capacity of network)
● Minimization of storage bandwidth subject to this lower bound
22. Distributed storage
● We are living in an internet age
● Demand for large scale data storage has increased
significantly
● Social networks, file and video sharing require
seamless storage, access and security for massive
amounts of data
● Storage mediums(viz. hard-drives) are individually
unreliable
● Hence we introduce redundancy via the use of
erasure codes to improve reliability

● Introduction
● The repair problem
● Reduction of repair problem to single source multicast network
● Family of single source multi-cast networks arising from the
reduction
● A lower bound on min-cuts(i.e. An upper bound on max-flow
and hence coding capacity of network)
● Minimization of storage bandwidth subject to this lower bound
26. Problem Definition
● Storage nodes are distributed and connected in a network
● Together they represent some storage code(MDS or
approximate MDS like LDPC)
● The issue of repairing a node arises when a storage node of the
system fails
● The still functioning nodes are called active nodes
● A newcomer node called repair node must connect to a subset
of active nodes, obtain information from them and reconstruct
the storage code i.e, repair the code
● The objective is to minimize amount of information transferred
in this process
29. The repair problem
● Data object (2Mb) is divided into two fragments:
y1
,y2
(1 Mb each)
● 4 encoded fragments generated: x1
,x2
,x3
,x4
(1 Mb
each)
● x4
fails, x5
, the newcomer needs to communicate
with existing nodes and create a new encoded
packet
● Any two out of x1
,x2
,x3
,x5
must suffice to recover
original data object
30. The repair problem
● What(and how much) should x1
,x2
,x3
communicate to
x5
such that are minimized?
x1
x2
x3
x4
y1
y2
x5
Example 1: A (4,2) MDS code
31. Variants of the repair problem
● Exact Repair: Failed blocks are exactly regenerated
i.e. newcomer node must reconstruct exact replica of
encoded block in the failed node
● Functional Repair: Newly generated data block
need not be exact replica of encoded block on the
failed node
● Exact repair of the systematic part: Only repair the
systematic part exactly so there is always a un-
coded copy of original file available
