Impersonality in Elizabeth Bishop's The Fish

Elizabeth Bishop(1911-1979), one of the most important and distinguished poets in the twentieth-century American literary world, is recognized as unique mainly for her objective and the imaginative images and the detachment in her poetry. Her poetry emphasizes the emotional self-control and avoids the description of individual life. This style is just coincided with T. S.Eliot's theory of impersonality. The article attempts to analyze the specific use of impersonality in Bishop's poem The Fish from two aspects: the objective description of the fish and the revelation of the universal truth.

Novel Homomorphic Encryption for Mitigating Impersonation Attack in Fog Computing

Fog computing is a rapidly growing technology that aids in pipelining the possibility of mitigating breaches between the cloud and edge servers.It facil-itates the benefits of the network edge with the maximized probability of offering interaction with the cloud.However,the fog computing characteristics are suscep-tible to counteract the challenges of security.The issues present with the Physical Layer Security(PLS)aspect in fog computing which included authentication,integrity,and confidentiality has been considered as a reason for the potential issues leading to the security breaches.In this work,the Octonion Algebra-inspired Non-Commutative Ring-based Fully Homomorphic Encryption Scheme(NCR-FHE)was proposed as a secrecy improvement technique to overcome the impersonation attack in cloud computing.The proposed approach was derived through the benefits of Octonion algebra to facilitate the maximum security for big data-based applications.The major issues in the physical layer security which may potentially lead to the possible security issues were identified.The potential issues causing the impersonation attack in the Fog computing environment were identified.The proposed approach was compared with the existing encryption approaches and claimed as a robust approach to identify the impersonation attack for the fog and edge network.The computation cost of the proposed NCR-FHE is identified to be significantly reduced by 7.18%,8.64%,9.42%,and 10.36%in terms of communication overhead for varying packet sizes,when compared to the benchmarked ECDH-DH,LHPPS,BF-PHE and SHE-PABF schemes.

On the Relationship between T. S. Eliot and the New Criticism from Their Opinions on Literary Work and Reader

T. S. Eliot is always considered as the pioneering father and founder of the New Criticism. This paper compares the similarities and differences of T. S. Eliot's relevant theories with those of the New Criticism from two aspects: their viewpoints of the literary works and those of the reader. It concludes that though they share the same belief in the importance of the literary works, the New Criticism is good at the subtle analysis of one text and another. However, Eliot recognizes the reader's function in the appreciation of the works which New Criticism totally objects to, and their responses should be properly considered in the criticism of the works.

An enhanced scheme for mutual authentication for healthcare services

With the advent of state-of-art technologies,the Telecare Medicine Information System(TMIS)now offers fast and convenient healthcare services to patients at their doorsteps.However,this architecture engenders new risks and challenges to patients'and the server's confidentiality,integrity and security.In order to avoid any resource abuse and malicious attack,employing an authentication scheme is widely considered as the most effective approach for the TMIS to verify the legitimacy of patients and the server.Therefore,several authentication protocols have been proposed to this end.Very recently,Chaudhry et al.identified that there are vulnerabilities of impersonation attacks in Islam et al.'s scheme.Therefore,they introduced an improved protocol to mitigate those security flaws.Later,Qiu et al.proved that these schemes are vulnerable to the man-in-the-middle,impersonation and offline password guessing attacks.Thus,they introduced an improved scheme based on the fuzzy verifier techniques,which overcome all the security flaws of Chaudhry et al.'s scheme.However,there are still some security flaws in Qiu et al.'s protocol.In this article,we prove that Qiu et al.'s protocol has an incorrect notion of perfect user anonymity and is vulnerable to user impersonation attacks.Therefore,we introduce an improved protocol for authentication,which reduces all the security flaws of Qiu et al.'s protocol.We also make a comparison of our protocol with related protocols,which shows that our introduced protocol is more secure and efficient than previous protocols.

Security Analysis of an Attractive Online Authentication Standard：FIDO UAF Protocol

FIDO(Fast IDentity Online) Alliance proposed a set of standard in 2014 for change the nature of online authentication. By now, it has drawn attention from many companies, including Google, VISA, Intel etc. In this paper, we analyze the FIDO UAF(Universal Authentication Framework) Protocol, one of the two sets of specifications in the standard. We first present protocols' cryptographic abstractions for the registration and authentication protocols of the FIDO UAF. According to the abstractions, we discuss on selected security goals presented in the standard to study UAF security properties. We also propose three attacks, which the first two are based on an assumption that an attacker can corrupt the software installed on the user device, and the third is based on two users sharing a FIDO roaming authenticator. The results of the attacks are to impersonate the legitimate user to pass the online authentication.

An efficient hash-based authenticated key agreement scheme for multi-server architecture resilient to key compromise impersonation

During the past decade,rapid advances in wireless communication technologies have made it possible for users to access desired services using hand-held devices.Service providers have hosted multiple servers to ensure seamless online services to end-users.To ensure the security of this online communication,researchers have proposed several multi-server authentication schemes incorporating various cryptographic primitives.Due to the low power and computational capacities of mobile devices,the hash-based multi-server authenticated key agreement schemes with offline Registration Server(RS)are the most efficient choice.Recently,Kumar-Om presented such a scheme and proved its security against all renowned attacks.However,we find that their scheme bears an incorrect login phase,and is unsafe to the trace attack,the Session-Specific Temporary Information Attack(SSTIA),and the Key Compromise Impersonation Attack(KCIA).In fact,all of the existing multi-server authentication schemes(hash-based with offline RS)do not withstand KCLA.To deal with this situation,we propose an improved hash-based multi-server authentication scheme(with offline RS).We analyze the security of the proposed scheme under the random oracle model and use the t4Automated Validation of Internet Security Protocols and Applications''(AVISPA)tool.The comparative analysis of communication overhead and computational complexity metrics shows the efficiency of the proposed scheme.

A lot of scholars and critics have done different researches on this poem.The author of this paper tries to analyze one of these poems from the perspective of T.S. Eliot's poetics.

Two-Dimensional Projection-Based Wireless Intrusion Classification Using Lightweight EfficientNet

Internet of Things(IoT)networks leverage wireless communication protocols,which adversaries can exploit.Impersonation attacks,injection attacks,and flooding are several examples of different attacks existing in Wi-Fi networks.Intrusion Detection System(IDS)became one solution to distinguish those attacks from benign traffic.Deep learning techniques have been intensively utilized to classify the attacks.However,the main issue of utilizing deep learning models is projecting the data,notably tabular data,into an image.This study proposes a novel projection from wireless network attacks data into a grid-based image for feeding one of the Convolutional Neural Network(CNN)models,EfficientNet.We define the particular sequence of placing the attribute values in a grid that would be captured as an image.Combining the most important subset of attributes and EfficientNet,we aim for an accurate and lightweight IDS module deployed in IoT networks.We examine the proposed model using the Wi-Fi attacks dataset,called the AWID2 dataset.We achieve the best performance by a 99.91%F1 score and 0.11%false-positive rate.In addition,our proposed model achieved comparable results with other statistical machine learning models,which shows that our proposed model successfully exploited the spatial information of tabular data to maintain detection accuracy.

Cryptanalysis and improvement of two new RFID protocols based on R-RAPSE

RFID(Radio Frequency IDentification)is a pioneer technology which has depicted a new lifestyle for humanity.Nowadays we observe an increase in the number of RFID applications and no one can ignore their numerous usage.An important issue with RFID systems is providing privacy requirements of these systems during authentication.Recently in 2014,Cai et al.proposed two improved RFID authentication protocols based on R-RAPS(RFID Authentication Protocol Security Enhanced Rules).We investigate the privacy of their protocols based on Ouafi and Phan privacy model and show that these protocols cannot provide private authentication for RFID users.Moreover,we show that these protocols are vulnerable to impersonation,DoS and traceability attacks.Moreover,we present two improved efficient and secure authentication protocols to ameliorate the performance of Cai et al.’s schemes.Our analysis illustrates that the existing weaknesses of the discussed protocols are eliminated in our proposed protocols.
