TL;DR: A novel suite of consensus protocols, FlexiTrust, is introduced that achieves up to 185% more throughput than their trust-bft counterparts and uncovers three fundamental limitations that preclude most practical deployments.
Abstract: The growing interest in reliable multi-party applications has fostered widespread adoption of Byzantine Fault-Tolerant (bft) consensus protocols. Existing bft protocols need f more replicas than Paxos-style protocols to prevent equivocation attacks. trust-bft protocols seek to minimize this cost by making use of trusted components at replicas. This paper makes two contributions. First, we analyze the design of existing trust-bft protocols and uncover three fundamental limitations that preclude most practical deployments. Some of these limitations are fundamental, while others are linked to the state of trusted components today. Second, we introduce a novel suite of consensus protocols, FlexiTrust, that attempts to sidestep these issues. We show that our FlexiTrust protocols achieve up to 185% more throughput than their trust-bft counterparts.

TL;DR: Only an authorized person will be able to transmit and receive the data through optical link by using biometric at transmitter end and code lock at receiver end and hence secure transmission of data can be done.
Abstract: The rate of crime, intruders and vandals is increasing day by day and the security gadgets still need to be modified so that we can make the transmission of information more secure. To end this, we need to design a cheap and effective intelligent and advance security system which can use advance technologies like biometric, code lock and optical link for the safe and secure transmission of information. By this technique only an authorized person will be able to transmit and receive the data through optical link by using biometric at transmitter end and code lock at receiver end and hence secure transmission of data can be done.

TL;DR: This research paper is focusing on a secure communication where biometric system can be used as a good and effective security option and automation can be achieved at the receiver end from the transmitter end.
Abstract: With the explosion of information traffic due to the Internet, electronic commerce, computer networks, multimedia, voice, data, and video, the need for a transmission medium with the bandwidth capabilities for handling such vast amounts of information is paramount. Fiber optics, with its comparatively infinite bandwidth, has proven to be the solution. The security inherent in optical fiber systems is a major benefit. The increasing rate of crime, attacks by thieves, intruders and vandals, despite all forms of security gadgets and locks, still need the attention. To make optical link more secure many devices can be used for transmission and reception purpose. These devices may be DNA sensor lock, card sensor lock, electronic eye lock, thumbprint sensor lock and electronic combination lock. In this research paper we are focusing on a secure communication where biometric system can be used as a good and effective security option. An important and very reliable human identification method is fingerprint identification. As fingerprint of every person is unique thus it can be used in various security options. Fingerprint recognition at the transmitter side allows only valid person to transmit the signal. At the receiver side code lock security can be economic and good option to allow only valid user to receive the information which has been sent through secure optical link. During communication over the optical link, automation can also be achieved at the receiver end from the transmitter end. With the help of automation, energy consumption at the receiver end can be reduced upto a great extent from the transmitter end.

TL;DR: This paper is a proposal to develop a project which is combination of two major security systems that are biometric security system and optical fiber link, which can provide security where secure communication is required such as bank, industry, college and election commission etc.
Abstract: Communication is an important part of our daily life. The communication process involves information generation, transmission, reception and interpretation. A technical overview of the emerging technologies of fiber optical communication and optical networking fiber optical communications has enabled much higher data rates. In present scenerio it is continuously being noticed that people are very concerned about privacy of their data. But some unauthorized persons, who are little bit advanced in technology, can access other’s data. So to provide security to the people for their data multiple security systems are being used in the present scenario like biometric which is well known for being used in the security purpose and second one is optical fiber link which is also used for the security purpose. Other security systems are code lock, RF-ID etc. So in present scenario the biggest problem is to provide security where secure communication is required such as bank, industry, college and election commission etc. This paper is a proposal to develop a project which is combination of two major security systems that are biometric security system and optical fiber link. Through this project analog and digital data can be transmitted using highly secured optical fiber link while having a biometric security to transmit the data at the transmitter end and having a code lock security for reception purpose at the receiver end. Through this project automation can also be done at the receiver end from the transmitter end.

TL;DR: The Practical View-Change-Less Protocol (PVPP) as discussed by the authors is a high-throughput, simple, and reliable consensus protocol that combines a chained consensus design for replicating requests with a reduced message cost, and a novel Rapid View Synchronization protocol that enables robust and low-cost failure recovery.
Abstract: The emergence of blockchain technology has renewed the interest in consensus-based data management systems that are resilient to failures. To maximize throughput of these systems, we have recently seen several prototype consensus solutions that optimize for throughput at the expense of overall implementation complexity, high costs, and reliability. Due to this, it remains unclear how these prototypes will perform in real-world environments. In this paper, we present the Practical View-Change-Less Protocol PVP, a high-throughput, simple, and reliable consensus protocol. Central to PVP is the combination of (1) a chained consensus design for replicating requests with a reduced message cost; (2) the novel Rapid View Synchronization protocol that enables robust and low-cost failure recovery; and (3) a high-performance concurrent consensus architecture in which independent instances of the chained consensus operate concurrently to process requests with high throughput and without single-replica bottlenecks. Due to the concurrent consensus architecture, PVP greatly outperforms traditional primary-backup consensus protocols such as PBFT (by up to 430%), Narwhal (by up to 296%), and HotStuff (by up to 3803%). Due to its reduced message cost, PVP is even able to outperform RCC, a state-of-the-art high-throughput concurrent consensus protocol, by up to 23%. Furthermore, PVP is able to maintain a stable and low latency and consistently high throughput even during failures.
