Edge Centric IoT Security Part 1 Security is an important concept that could be examined from different angles. Although we expect IoT applications to have strong system security protections, securing IoT systems is still a challenge. As I studied before, There are some points of view to check out IoT security challenges such as User-Centric, […]

Evaluating a Blockchain-based Method for Industrial IoT Data Confidentiality: Proof of Concept

Utilizing the Internet of Things in the industry has led to an event called IIoT (Industrial Internet of Things) due to make smart cities, communication routes, smart grids, etc. IIoT deals with various sensors, devices scattered on the edges, and cloud servers by identified standards and protocols in decentralized networks. Besides all benefits the IIoT has carried out, the data stream’s security and privacy remain a debatable subject of this technology. There are many solutions to overcome security issues and confidentiality breaches, but some do not completely consider the purpose. Factors like speed, integrity, security, and power consumption must be considered, and of course, the cost factor is a significant role in achieving the goal. The purpose of this article is to introduce a new scheme evolved from Blockchain methodology to overcome privacy and data confidentiality challenges.

How TBLOCK works?

Structure of sensor datagram
Algorithm for metadata cycle

When the sensor switches on, a new round of data chunks is running. Three Algorithms present phases of this scheme as following. New_Round() means each round for data absorption which here is configured for 1 minute. Coincidence with data generation, the hash value of generation time with SHA-family cryptography methods, is created, then the datagram is formed () and hash values are transferred to modules within the ledger ().

An appropriate blockchain platform for IoT and industrial IoT, for instance, the BFT-based private blockchains according to potential performance and security of data (and user) is suitable for the IoT environment. Totally, private blockchains offer more security and better performance than public blockchains which permission not involved them. In this regard, Hyperledger-Fabric use endorsement policies to define which peers need to execute TXs. In this way, a given chain code can be kept private from peers that are not part of endorsement policy

An IoT-centric consensus protocol must have the capability to sustain maximum possible faulty nodes. Moreover, the IoT systems are vulnerable to physical or cyber attacks, the most important consideration to lessen the effect of faulty nodes is to carry out integrity check of validator nodes so any dishonest node makes contribution on related process. Besides that, the issue of scalability concerning the management of ever-increasing blockchain size on IoT devices can be addressed by various blockchain architectures. For example, sidechain and treechain blockchain. As[23] states a sidechain is a decentralized p2p network which stores sensor data on an off-chain network of private nodes in the form of DHT, in this model the blockchain contains the pointers to data and not all the nodes replicate all TXs.

Hence the scheduling of tasks in cloud computing is very important that try to determine an efficient scheduling and source allocation. In fact, the goal is determining a processing resource from set of resources that a task needs for process, so that can process more jobs in less time. Scheduling system controls different functions in cloud system for increasing job completion rate, resource efficiency and in consequence increasing the computing power. In this study, we provide approach base on lottery algorithm to reach those goals with minimize make-span time. Simulation of proposed method is by “CloudSim” application

The Proposed method:

As noted earlier in task timing issues in cloud computing, the output is a proper mapping of tasks to resources. So that parameters such as response time, make-span time and performance of data centers, are optimized. In this report, we present a new algorithm based on lottery algorithm. The proposed algorithm has evolutionary view and most prominent characteristic of it is being agile. Stages of it are as follows:

First step: number of answers is created randomly, which either is discussed as a participant in proposed method.

Second step: the propriety of each participant is measured :

Fi=value obtained for task i Tlen=length of ith task

Rw=workloads that are already on the CPU which ith task is allocated for it

NCC=communication cost for the selected virtual machine for ith task or data broker Fitness total=the answer fitness

Third step: each participant assigned a fitness based on the number of sheets. Indeed, participants who had more points will have more sheets. Forth step: lottery is done. There is one win rate equal to 0.8. indeed, what it means is that in each iteration 80% of current stage’s participants are transported to new stage. 20% of the initial population consist of participants. For lottery, we have used randomly numbers with uniform dispatch. Fifth step: we check end condition in this stage. In our proposed method, the end condition is specific number of repetition, but we can consider the end condition near an optimal condition.

An old-fashion study about trust in wireless sensor networks and offer a new resolve to management the battery energy of nodes

When we hear about universal communications and technologies promotion, unconsciously, distant borders and how confidence in this type of communication challenges the minds. The challenge of its kind in recent years, has been creating stable and unstable relations in the field of ICT.
We propose to review trust challenges of wireless sensor networks then we would like to present appropriate resolve for optimizing the battery life of sensors in which nodes communicate in a sensor network. In this paper, we tried to show better mechanism to optimize batteries in fields of medical, military and investigation laboratories. I believe that an important trusty field in WSN is the battery life of sensor node, because of financial issues for implementation phase. In fact, if we could prove this idea which management of sensor nodes with considering a special mechanism for saving energy of batteries, then it’ll be applicable in some areas such as space researches to finding life in other planets. Due to the previous essays about resolving the trust challenged, we considered to show different method for saving more energy to batteries.in this case, we illustrated a combination of LEACH and SPIN algorithms, with little changes.
