An Efficient Lightweight Provably Secure Authentication Protocol for Patient Monitoring Using Wireless Medical Sensor Networks

The refurbishing of conventional medical network with the wireless medical sensor network has not only amplified the efficiency of the network but concurrently posed different security threats. Previously, Servati and Safkhani had suggested an Internet of Things (IoT) based authentication scheme for the healthcare environment promulgating a secure protocol in resistance to several attacks. However, the analysis demonstrates that the protocol could not withstand user, server, and gateway node impersonation attacks. Further, the protocol fails to resist offline password guessing, ephemeral secret leakage, and gateway-by-passing attacks. To address the security weaknesses, we furnish a lightweight three-factor authentication framework employing the fuzzy extractor technique to safeguard the user’s biometric information. The Burrows-Abadi-Needham (BAN) logic, Real-or-Random (ROR) model, and Scyther simulation tool have been imposed as formal approaches for establishing the validity of the proposed work. The heuristic analysis stipulates that the proposed work is impenetrable to possible threats and offers several security peculiarities like forward secrecy and three-factor security. A thorough analysis of the preexisting works with the proposed ones corroborates the intensified security and efficiency with the reduced computational, communication, and security overheads

An anonymous authentication and key establish scheme for smart grid: FAuth

The smart meters in electricity grids enable fine-grained consumption monitoring. Thus, suppliers could adjust their tariffs. However, as smart meters are deployed within the smart grid field, authentication and key establishment between smart grid parties (smart meters, aggregators, and servers) become an urgency. Besides, as privacy is becoming a big concern for smart meters, smart grid parties are reluctant to leak their real identities during the authentication phase. In this paper, we analyze the recent authentication schemes in smart grids and other applied fields, and propose an anonymous authentication and key establishment scheme between smart grid parties: FAuth. The proposed scheme is based on bilinear maps and the computational Diffie–Hellman problem. We changed the way the smart meter parties registered at Key Generation Center, making the proposed scheme robust against various potential attacks that could be launched by the Key Generation Center, as the scheme could avoid the private key of the smart meter parties from leaking to the Key Generation Center. Besides, the proposed scheme reduced the computational load, both at the smart meter side and at the aggregator side, which make it perfectly suitable for computation-constrained devices. Security proof results show the proposed scheme is secure under the BAN logic and random oracle model

개선된 인증과 키 분배 기법

학위논문 (박사)-- 서울대학교 대학원 : 수리과학부, 2014. 2. 김명환.Nowadays, anonymity property of user authentication scheme becomes important. From 2003, Park et al., Juang et al., and other researchers proposed a useful, secure and efficient authenticated-key exchange scheme. However, There schemes did not provide the useful methods against the various efficient attacks. They argued that they provided the identity privacy- mutual authentication-half-forward secrecy. But their suggestions have limited solutions. So we have researched the about 30 papers and suggested an improved authentication and key exchange scheme. Then, we show that the proposed scheme is secure against the various attacks methods (linear attack, inverse, dictionary, MTMD attacks etc).Chapter 1 Introduction ........................................................ 6 1.1 Motivation ...............................................................................6 1.2 Organization ............................................................................8 Chapter 2 Secure Authenticated Key Exchange .................. 11 2.1 AKE Security ........................................................................11 2.2 Protocol Attack Types ...........................................................17 Chapter 3Secure Authenticated Key Exchange ................... 19 3.1 The Authentication Key Protocol..........................................19 3.2 General Security-Analysis Discussion..................................26 Chapter 4Authenticated Key Exchange Protocol................ 40 4.1 The Improved AKE ...............................................................41 4.2 An Improved Anonymous AKE Scheme ..............................62 Chapter 5Conclusion ...................................................... 75 Bibliography .................................................................... 77 Abstract ........................................................................... 87Docto

Secure Identification in Social Wireless Networks

The applications based on social networking have brought revolution towards social life and are continuously gaining popularity among the Internet users. Due to the advanced computational resources offered by the innovative hardware and nominal subscriber charges of network operators, most of the online social networks are transforming into the mobile domain by offering exciting applications and games exclusively designed for users on the go. Moreover, the mobile devices are considered more personal as compared to their desktop rivals, so there is a tendency among the mobile users to store sensitive data like contacts, passwords, bank account details, updated calendar entries with key dates and personal notes on their devices. The Project Social Wireless Network Secure Identification (SWIN) is carried out at Swedish Institute of Computer Science (SICS) to explore the practicality of providing the secure mobile social networking portal with advanced security features to tackle potential security threats by extending the existing methods with more innovative security technologies. In addition to the extensive background study and the determination of marketable use-cases with their corresponding security requirements, this thesis proposes a secure identification design to satisfy the security dimensions for both online and offline peers. We have implemented an initial prototype using PHP Socket and OpenSSL library to simulate the secure identification procedure based on the proposed design. The design is in compliance with 3GPP‟s Generic Authentication Architecture (GAA) and our implementation has demonstrated the flexibility of the solution to be applied independently for the applications requiring secure identification. Finally, the thesis provides strong foundation for the advanced implementation on mobile platform in future

Lightweight payload encryption-based authentication scheme for advanced metering infrastructure sensor networks

The Internet of Things (IoT) connects billions of sensors to share and collect data at any time and place. The Advanced Metering Infrastructure (AMI) is one of the most important IoT applications. IoT supports AMI to collect data from smart sensors, analyse and measure abnormalities in the energy consumption pattern of sensors. However, two-way communication in distributed sensors is sensitive and tends towards security and privacy issues. Before deploying distributed sensors, data confidentiality and privacy and message authentication for sensor devices and control messages are the major security requirements. Several authentications and encryption protocols have been developed to provide confidentiality and integrity. However, many sensors in distributed systems, resource constraint smart sensors, and adaptability of IoT communication protocols in sensors necessitate designing an efficient and lightweight security authentication scheme. This paper proposes a Payload Encryption-based Optimisation Scheme for lightweight authentication (PEOS) on distributed sensors. The PEOS integrates and optimises important features of Datagram Transport Layer Security (DTLS) in Constrained Application Protocol (CoAP) architecture instead of implementing the DTLS in a separate channel. The proposed work designs a payload encryption scheme and an Optimised Advanced Encryption Standard (OP-AES). The PEOS modifies the DTLS handshaking and retransmission processes in PEOS using payload encryption and NACK messages, respectively. It also removes the duplicate features of the protocol version and sequence number without impacting the performance of CoAP. Moreover, the PEOS attempts to improve the CoAP over distributed sensors in the aspect of optimised AES operations, such as parallel execution of S-boxes in SubBytes and delayed Mixcolumns. The efficiency of PEOS authentication is evaluated on Conitki OS using the Cooja simulator for lightweight security and authentication. The proposed scheme attains better throughput while minimising the message size overhead by 9% and 23% than the existing payload-based mutual authentication PbMA and basic DTLS/CoAP scheme in random network topologies with less than 50 nodes

Authentication Protocols for Internet of Things: A Comprehensive Survey

In this paper, a comprehensive survey of authentication protocols for Internet of Things (IoT) is presented. Specifically more than forty authentication protocols developed for or applied in the context of the IoT are selected and examined in detail. These protocols are categorized based on the target environment: (1) Machine to Machine Communications (M2M), (2) Internet of Vehicles (IoV), (3) Internet of Energy (IoE), and (4) Internet of Sensors (IoS). Threat models, countermeasures, and formal security verification techniques used in authentication protocols for the IoT are presented. In addition a taxonomy and comparison of authentication protocols that are developed for the IoT in terms of network model, specific security goals, main processes, computation complexity, and communication overhead are provided. Based on the current survey, open issues are identified and future research directions are proposed
