“…Table I depicts the four categories of these methods based on the taxonomy. L. Zhang et al [15] proposed a general purpose framework that stores user's identity in the blockchain and exploits a smart contract for managing different permissions based on user's related data for different websites. This method consists of four main actors (i.e.…”

As the first step in preserving system security, Authentication and Access Control (AAC) plays a vital role in all businesses. Recently, emerging the blockchain and smart contract technology has attracted significant scientific interest in research areas like authentication and access control processes. In the context of authentication and access control, blockchain can offer greater data and rule confidentiality and integrity, as well as increasing the availability of the system by removing the single point of failure in the procedure. To categorize and find the most important open problems in this research area, having a comprehensive review is crucial. To the best of our knowledge, for the first time in this survey, we aim to describe the current state of the art in deploying blockchain and smart contracts specifically in authentication and access control. Following an introduction to AAC and blockchain technology, we present a brief background of distributed ledger technology, access control and authentication. To offer a clearer understanding of the state of the art, we propose taxonomy to categorize the existing methods based on their type, application environment and their justification for exploiting blockchain. For the conclusion of the paper, we examined the advantages and disadvantages of the proposed method in different contexts like security, resource consumption and privacy. Also we discussed about the future work.

“…The basic assumptions considered in the electricity supply model are given in Table 2 In addition to the above, Table 3 provides the various input parameters employed in this study model which include power generation capacity of each generation method, installed generation capacity, the amount of fuel consumed, electricity generated alongside fixed and variable costs as well as efficiency, availability in percentages, lifetime, and merit order for the base year (2017). [21][22][23] It is pertinent to mention that the electricity generation in 2017 was 94.8 TWh which is just 6% of projected electricity generation (2374 TWh) in 2055.…”

Pakistan has faced an electricity shortfall for over two decades despite various efforts taken at different levels. Though electricity supply in recent times has crossed the demand, the supply‐side stresses and deciding optimal power generation pathways have always been a challenge for policymakers and researchers. In this study using a LEAP energy model, following the sectoral electricity demand forecast, four supply‐side scenarios have been developed and analyzed for the study period 2017‐2055. In each scenario, referred to as Business as Usual (BAU), Renewable Energy Technologies (RET), Coal Power Penetration (CPP), and High‐Efficiency Low‐Emission (HELE) scenario, electricity generation, installed generation capacity, cost of production, and GHG emissions are estimated and compared for seeking long‐term optimal energy pathways for Pakistan. The study results reveal that for the end year (2055), RET is an environmentally sustainable scenario with an estimated electricity generation of 2421 TWh, which is enough to meet the electricity demand of 2374TWh. The GHG emissions under the RET scenario are estimated to be 857 million metric Tons, which are around 50% less than CPP and 40% less than the BAU scenario. However, the cost of generation is higher than BAU and CPP scenarios. The CPP scenario emerges to be cost‐competitive, however with the highest GHG emissions. This study thus suggests that convergence of RET with the CPP scenario could be an appealing option for Pakistan to meet increasing demand with energy security and environmental sustainability.

“…Lewison and Corella [20]proposed a certificate-based PKI authentication system based on the Ethereum blockchain, which solves the problems of excessive communication in traditional PKI certificate management and the use of CRLs. Zhang et al [21] solved the centralization problem of the traditional PKI system by using blockchain technology. In their framework, users store their identities on the blockchain and attach a smart contract to grant different permissions for each site or application, thereby enabling an entirely distributed user authentication framework.…”

With the rising popularity of the Internet and the development of big data technology, an increasing number of organizations are opting to cooperate across domains to maximize their benefits. Most organizations use public key infrastructure to ensure security in accessing their data and applications. However, with the continuous development of identity-based encryption (IBE) technology, small- and medium-sized enterprises are increasingly using IBE to deploy internal authentication systems. To solve the problems that arise when crossing heterogeneous authentication domains and to guarantee the security of the certification process, we propose using blockchain technology to establish a reliable cross-domain authentication scheme. Using the distributed and tamper-resistant characteristics of the blockchain, we design a cross-domain authentication model based on blockchain to guarantee the security of the heterogeneous authentication process and present a cross-domain authentication protocol based on blockchain. This model does not change the internal trust structure of each authentication domain and is highly scalable. Furthermore, on the premise of ensuring security, the process of verifying the signature of the root certificate in the traditional cross-domain authentication protocol is improved to verify the hash value of the root certificate, thereby improving the authentication efficiency. The developed prototype exhibits generality and simplicity compared to previous methods.
