Problem Statement (1/3) 8
The issues of insecure, and non-trusted environment of [2] discourage prosumers from data sharing. Generating new key pairs for each
changed ID and multiple pseudonyms for each user of [10] and [11] create traceability issues for blockchain’s transactions audit.
Mapping of the dummy and real account of [12] will lead to the additional computational burden as the proposed system requires extra
gas consumption for both transactions. Double auction mechanism proposed by [13] involves entities that act as sellers and buyers, who
can auction price within the localized trading environment. However, the proposed system takes much computational time and it
becomes impractical when one auctioneer is not willing to participate in the cumbersome auctioning at every hour in a day and with
insufficient power capacity. Furthermore, the authors in [14] propose non-monetary incentive as high priority ranking to users for using
more energy. However, authors fail to consider that the hoarding of energy by high priority users that is supposed to be shared with other
users results in dissatisfaction and resentment.
Authors in [1] provide a setup of a centralized server coordinating the energy trading between EVs and CSs to minimize cost. However,
trading is made in a non-trusted and insecure environment. Authors in [8], [9] and [13] propose a setup of blockchain based energy
trading between EVs and CSs to maximize the social welfare and enhance EVs' satisfactions. However, they do not consider the pricing
policy and privacy of EVs in terms of their locations. Authors in [15] provide privacy preserving for prosumers about their energy
consumption, energy prices and social welfare maximization; however, authors do not consider that the insecure environment and
disclosure of prosumers’ locations also raise privacy concerns.

Grids. IEEE Transactions on Engineering Management, 1-13.
Authors in [16] propose levelized cost of energy for decentralized solar power systems in SSA. In their framework, a standalone solar
home system (SHS) is considered with solar and battery capacities using a fraction of demand serve (FDS). Also, FDS is used to
measure the reliability via a multi-step optimization to derive the least-cost system and energy costs minimization using Newton’s
method. However, the authors do not consider energy reliability in terms of security, privacy and energy exchange for the decentralized
SHS. Also, Newton’s method requires the use of a second order partial derivative, which is tedious to compute and time-consuming. In
addition, the authors do not consider the working capital, and service level to quantify the reliability on generation costs. Furthermore,
they do not include the payment system such as pay-as-you-go and also do not address behaviors of electricity user with regard to non-
payment of electricity bill.
Authors in [17] propose a deep learning as an intrusion detection system using the recurrent neural network (RNN) for detecting
network attacks and fraudulent activities within the blockchain network. The authors use bilinear mapping, short signatures and hashes
to provide privacy preserving of energy trading transactions. However, the proposed scheme does not address privacy threat from
differential attack, collusion attack and dishonest behavior in updating and gradient collecting parameters of RNN. Also, they do not
consider privacy preserving of energy users from re-identification attack and method of data collection.
