An Anonymous Identity-based With Bilateral Protocol for Smart Grid

Smart Grid (SG) is a modern digital metering system that was introduced by researchers to take over the traditional electricity infrastructure that existed before by gathering and putting in use the data generated by smart meters and ensure efficiency and reliability in the two directional flow of electricity and data for both the service providers and smart meters. Leakage of customers’ identity causes inconvenience to the customer because he is exposed to theft in his household. Secure anonymous key distribution scheme for SG has been proposed as solution to secure data transfer between service provider and customer. Existing secure anonymous key distribution scheme for SG brings challenge such as being inefficient, having traceability issues and do not stop replay attack hence vulnerable to DoS attacks. In this paper a Secure efficient anonymous identity-based with bilateral protocol is proposed to address the weakness in existing anonymous key distribution schemes. , With this protocol, both smart meter and service provider in (SG) identify each other anonymously in efficient way achieving un-traceability and restisting Replay and DoS attack.

An Anonymous Key Distribution Scheme for Group Healthcare Services in 5G-Enabled Multi-Server Environments

Fifth generation (5G) mobile technology enables a new kind of network that provides high peak data rates, ultra-low latency communication and high user density. Electronic healthcare (e-health) allows the data to be stored and shared in a highly efficient and flexible manner. Group e-health services help in improving long-term results of the treatments due to its collaborative characteristic. The services including real-time remote patient monitoring and transmission of large health data files can be facilitated by e-health systems enabled with the 5G network. Since the communication channel is open, security and privacy in the system should be taken into account. Our work proposes a key distribution scheme for group healthcare services in 5G network environments. We construct various healthcare domains and apply the proposed scheme to the group services. The paper also introduces Single Sign-On (SSO), a cost-efficient solution, for multi-server architecture of the constructed system. Security and privacy of the scheme are enforced by a three-factor authentication mechanism (integrating smart card, password and biometrics) and strong user anonymity property. We provide security proof of the proposed scheme using various well-known tools including RoR model, BAN logic and AVISPA simulation. Results of various performance comparisons indicate that our scheme provides most functions and bears rational costs, compared with its related works.

Lightweight anonymous key distribution scheme for smart grid using elliptic curve cryptography

Due to efficiency, security and reliability, the smart grid attracts more and more attentions from both industry and researchers. To implement secure communication in the smart grid, how to distribute secret keys among participants become an important issue. Several key distribution schemes for the smart grid have been proposed to guarantee secure communication. However, most of them cannot provide smart meter anonymity or have unsatisfactory performance. Based on the identity-based cryptography, this study proposes an anonymous key distribution (AKD) scheme for the smart grid using the elliptic curve cryptography. The proposed AKD scheme can provide the smart meter anonymity and mutual authentication between two participants without any help of the trusted anchor. Due to the fact that no bilinear paring operation is involved in the execution, the proposed AKD scheme has much better performance than the latest AKD scheme proposed by Tsai and Lo. Detailed performance analysis shows that the computation and the communication costs of the authors' AKD scheme is about 82.39 and 52.33% less than that of Tsai and Lo's AKD scheme. Besides, security analysis shows that the proposed AKD scheme is provably secure in the random oracle model.

Cloud-Assisted Key Distribution in Batch for Secure Real-time Mobile Services

Establishing promising and efficient key distribution is the cornerstone of security when applying cryptographic methods to guard the privacy of smart devices in the Internet of Things (IoT). However, when using conventional key distribution methods in real-time mobile services, it is usually deficient to build multiple channels with strong security simultaneously on a single data server. Therefore, we focus our research on collecting or monitoring real-time and remote data, which is commonly observed in the health care field of the IoT. In this research, there are difficulties to apply the conventional key distribution approaches during interactions when considering both security and efficiency. Moreover, when preserving personal privacy, anonymity is also important in key distribution processes. We design a system of real-time mobile services and the related security requirements in this paper, and apply a novel and interesting Identity-Based Key Encapsulation Mechanism (IBKEM) to instantiate our system and achieve anonymous key distribution with only one-pass communication for mobile clients in batch. Our instantiated system demonstrates both strong security and practice.

Secure Anonymous Key Distribution Scheme for Smart Grid

To fully support information management among various stakeholders in smart grid domains, how to establish secure communication sessions has become an important issue for smart grid environments. In order to support secure communications between smart meters and service providers, key management for authentication becomes a crucial security topic. Recently, several key distribution schemes have been proposed to provide secure communications for smart grid. However, these schemes do not support smart meter anonymity and possess security weaknesses. This paper utilizes an identity-based signature scheme and an identity-based encryption scheme to propose a new anonymous key distribution scheme for smart grid environments. In the proposed scheme, a smart meter can anonymously access services provided by service providers using one private key without the help of the trusted anchor during authentication. In addition, the proposed scheme requires only a few of computation operations at the smart meter side. Security analysis is conducted to prove the proposed scheme is secure under random oracle model.
