“…Here, the valid request can be captured and resent after a periodic interval to send time-critical data, which can raise false alarms in industries [28]. Code Injection: Code injection happens when malicious code is passed as input to a vulnerable computer program or web application, which results in unexpected output [3]. Session Hijacking: Session/HTTP cookies are used to validate a session; if an attacker can steal the live session cookies, he can take over the session, which is known as session hijacking.…”

Industrial companies can use blockchain to assist them in resolving their trust and security issues. In this research, we provide a fully distributed blockchain-based architecture for industrial IoT, relying on trust management and reputation to enhance nodes’ trustworthiness. The purpose of this contribution is to introduce our system architecture to show how to secure network access for users with dynamic authorization management. All decisions in the system are made by trustful nodes’ consensus and are fully distributed. The remarkable feature of this system architecture is that the influence of the nodes’ power is lowered depending on their Proof of Work (PoW) and Proof of Stake (PoS), and the nodes’ significance and authority is determined by their behavior in the network. This impact is based on game theory and an incentive mechanism for reputation between nodes. This system design can be used on legacy machines, which means that security and distributed systems can be put in place at a low cost on industrial systems. While there are no numerical results yet, this work, based on the open questions regarding the majority problem and the proposed solutions based on a game-theoretic mechanism and a trust management system, points to what and how industrial IoT and existing blockchain frameworks that are focusing only on the power of PoW and PoS can be secured more effectively.

“…IoT devices can easily be a goal of distributed denial-of-service attacks, malicious attackers, and security data breaches. The marriage of IoT and blockchain opens the doors to new opportunities which eliminate inherent inefficiencies, increase security and enhance transparency among all parties involved while allowing safe machine-to-machine transactions [33]. Figure 2 shows blockchain and IoT advantages.…”

This paper provides an overview of blockchain technology's security and privacy features, as well as an overview of IoT-based cache memory and single-bit six transistor static random-access memory cell sense amplifier architecture. Each chip's memory is used for recorded as blocks, which are encrypted and used as a blockchain for other memory devices. The architectures comprise of the circuit of write driver, six transistor static random access memory cells, and sense amplifiers such as current differential sense amplifier, charge transfer differential sense amplifier, and voltage latch sense amplifier. Furthermore, different parameters such as the number of transistors, sensing delay, and power consumption have been analyzed for varying resistance values (i.e., R=42.3 and R=42.3K ). Apart from that, power reduction techniques such as dual sleep, forced stack, sleep transistor, and sleep stack are used to optimize power consumption. These power reduction techniques are applied over different blocks of architecture, such as six transistors static random access memory cell and sense amplifier to optimize power consumption of the architecture. The conclusion arises that a single-bit six transistor static random access memory cell with power reduction dual sleep technique voltage latch sense amplifier with power reduction dual sleep technique in architecture consumes 11.65µW of power and has 33 transistors which are lowest from other architectures.INDEX TERMS Circuit of write driver (CWD), sense amplifier (SA), current differential sense amplifier (CDSA), charge transfer differential sense amplifier (CTDSA), voltage latch sense amplifier (VLSA), six transistor static random-access memory (6T-SRAM).
