Cellular automata based multi-bit stuck-at fault diagnosis for resistive memory Research Article

Sutapa SARKAR, Biplab Kumar SIKDAR, Mousumi SAHA

Frontiers of Information Technology & Electronic Engineering 2022, Volume 23, Issue 7,   Pages 1110-1126 doi: 10.1631/FITEE.2100255

Abstract: This paper presents a group-based dynamic scheme intended for resistive random-access memory (ReRAM). Traditional static random-access memory, dynamic random-access memory, NAND, and NOR flash memory are limited by their scalability, power, package density, and so forth. Next-generation memory types like ReRAMs are considered to have various advantages such as high package density, non-volatility, scalability, and low power consumption, but has been a problem. Unreliable memory operation is caused by permanent stuck-at faults due to extensive use of write- or memory-intensive workloads. An increased number of stuck-at faults also prematurely limit chip lifetime. Therefore, a cellular automaton (CA) based dynamic stuck-at fault-tolerant design is proposed here to combat unreliable cell functioning and variable cell lifetime issues. A scalable, block-level fault diagnosis and recovery scheme is introduced to ensure readable data despite multi-bit stuck-at faults. The scheme is a novel approach because its goal is to remove all the restrictions on the number and nature of stuck-at faults in general fault conditions. The proposed scheme is based on Wolfram's null boundary and periodic boundary CA theory. Various special classes of CAs are introduced for 100% fault tolerance: (SACAs), (TACAs), and (MACAs). The target micro-architectural unit is designed with optimal space overhead.

Abstract:

A novel cellular automata (CA) — two-dimensional controllable CA — is proposed in this paper.  According to characteristics of two-dimensional controllable CA,  a pseudo random generating method based on two-dimensional controllable CA with a trapezoidal structure is presented.  Simulation demonstrates that pseudo random bit sequence generator based on the two-dimensional controllable CA with a trapezoidal structure is easily implemented,  and can generate high speed bit sequence and excellent statistical properties.  This novel CA is widely used in symmetrical cryptography.

A Multi-agent Model Based on Cellular Automata for Simulating Human Behavior to Assess Building Design

Fang Weifeng,Yang Lizhong,Huang Rui

Strategic Study of CAE 2003, Volume 5, Issue 3,   Pages 67-71

Abstract:

In recent years, Cellular Automata (CA) micro-simulation has emerged as an effective technique for modeling traffic flow and achieved a lot of success. But the human movement and occupant evacuation are much more complex than traffic flow. It is necessary for us to consider more human behavior characteristics if try to apply the model in practice. For the advantages of agent in simulating human intelligence, a multi-agent model based on CA is presented which focuses on simulating the human behavior and the effect on human by building structure. In the model, people are represented by agents and they move over the network which is represented by a lattice of cells. Agents can perceive the local environment and chcx)se their moving direction autonomously. In order to simulate human movement in very complex structure building the acquainting and evacuating states based on the ideas of artificial life are introduced and that is proved successful in simulation. Using this model the effect of the building structure on human behavior can be studied and the performance of building design can be assessed.

Evacuation Analysis of a Large Shopping Mall

Song Weiguo,Yu Yanfei,Zhang Heping

Strategic Study of CAE 2005, Volume 7, Issue 10,   Pages 78-83

Abstract:

Along with the development of the society, it flows out more and more high-rise, underground and large-space buildings, of which the fire protection designs are sometimes beyond the requirements of existing national fire protection codes of China. Therefore, the performance-based fire protection design of buildings has been getting more and more chances of application. Evacuation analysis is one of the key problems in the performance-based design. In this paper, the performance-based design of a large shopping mall is introduced, and a cellular automata (CA) based evacuation model, i.e. the CAFE model is used to analyze the efficiency of evacuation. Because the interactions among pedestrians and those between pedestrians and environment are quantified in CAFE model, the values of evacuation time obtained through the model are slightly larger than those of an evacuation software, Simulex, indicating that the CAFE model is to some extent more conservative and the analysis results are with higher reliability.

Identity-based threshold proxy re-encryption scheme from lattices and its applications Research Articles

Liqiang WU, Yiliang HAN, Xiaoyuan YANG, Minqing ZHANG,latticewj@163.com,hanyil@163.com

Frontiers of Information Technology & Electronic Engineering 2022, Volume 23, Issue 2,   Pages 258-277 doi: 10.1631/FITEE.2000366

Abstract: (TPRE) can prevent collusion between a single proxy and a delegatee from converting arbitrary files against the wishes of the delegator through multiple proxies, and can also provide normal services even when certain proxy servers are paralyzed or damaged. A non-interactive identity-based TPRE (IB-TPRE) scheme over is proposed which removes the public key certificates. To accomplish this scheme, Shamir‘s secret sharing is employed twice, which not only effectively hides the delegator‘s private key information, but also decentralizes the proxy power by splitting the re-encryption key. means that a combiner can detect a misbehaving proxy server that has sent an invalid transformed ciphertext share. This property is achieved by lattice-based fully homomorphic signatures. As a result, the whole scheme is thoroughly capable of resisting quantum attacks even when they are available. The security of the proposed scheme is based on the decisional learning with error hardness assumption in the standard model. Two typical application scenarios, including a file-sharing system based on a blockchain network and a robust key escrow system with threshold cryptography, are presented.

State space optimization of finite state machines from the viewpoint of control theory Research Article

Jumei Yue, Yongyi Yan, Zengqiang Chen, He Deng,yjm@mail.nankai.edu.cn,yyyan@mail.nankai.edu.cn

Frontiers of Information Technology & Electronic Engineering 2021, Volume 22, Issue 12,   Pages 1551-1684 doi: 10.1631/FITEE.2000608

Abstract: Motivated by the inconvenience or even inability to explain the mathematics of the state of (FSMs) in most existing results, we consider the problem by viewing FSMs as logical dynamic systems. Borrowing ideas from the concept of equilibrium points of dynamic systems in control theory, the concepts of -equivalent states and -source equivalent states are introduced. Based on the state transition dynamic equations of FSMs proposed in recent years, several mathematical formulations of -equivalent states and -source equivalent states are proposed. These can be analogized to the necessary and sufficient conditions of equilibrium points of dynamic systems in control theory and thus give a mathematical explanation of the optimization problem. Using these mathematical formulations, two methods are designed to find all the -equivalent states and -source equivalent states of FSMs. Further, two ways of reducing the state space of FSMs are found. These can be implemented without computers but with only pen and paper in a mathematical manner. In addition, an open question is raised which can further improve these methods into unattended ones. Finally, the correctness and effectiveness of the proposed methods are verified by a practical language model.

Research & application of IFN in cypher science

Strategic Study of CAE 2008, Volume 10, Issue 5,   Pages 51-57

Abstract:

To overcome 3 shortcomings of the traditional PNCT (pure numerals ciphering technology) of that, properties of the divulging a secret, the allotted time and the dead secrets. This paper gives a novel ciphering technique based on specific properties of intelligent VCN (variable carrying numbers). All allowed cipher numbers are FCN (fixed carrying numbers), in the traditional PNCT, and their changing rules of FCN are both very simple, mechanism and too difficult to be remembered, so that they make the mentioned shortcomings of being sure secrecy in the course of nature. The VCN are extension of the FCN, which are also a new concept of numbers in a broad sense, but their complex,intelligence and flexibility in changing rules are just to overcome the 3 shortcomings of PNCT in FCN.
