Lightweight Authentication and Key Agreement for Smart Metering in Smart Energy NetworksAuthentication and Key Agreement • July 17th, 2018
Abstract—Smart meters are considered as foundational part of the smart metering infrastructure (SMI) in smart energy networks. Smart meter is a digital device that makes use of two- way communication between consumer and utility to exchange, manage and control energy consumptions within a home. How- ever, despite all the features, a smart meter raises several security- related concerns. For instance, how to exchange data between the legal entities (e.g., smart meter and utility server) while maintaining privacy of the consumer. To address these concerns, authentication and key agreement in SMI can provide important security properties that not only to maintain a trust between the legitimate entities but also to satisfy other security services. This work presents a lightweight authentication and key agreement (LAKA) that enables trust, anonymity, integrity and adequate security in the domain of smart energy network. The proposed scheme employs hybrid cryptography to facilitate mutual tr
Instant and Robust Authentication and Key Agreement among Mobile DevicesAuthentication and Key Agreement • August 29th, 2016
Device-to-device communication is important to emerging mobile applications such as Internet of Things and mobile social networks. Authentication and key agreement among multiple legitimate devices is the important first step to build a secure communication channel. Existing solutions put the devices into physical proximity and use the common radio environment as a proof of identities and the common secret to agree on a same key. However they experience very slow secret bit generation rate and high errors, requiring sev- eral minutes to build a 256-bit key. In this work, we design and implement an authentication and key agreement proto- col for mobile devices, called The Dancing Signals (TDS), being extremely fast and error-free. TDS uses channel state information (CSI) as the common secret among legitimate devices. It guarantees that only devices in a close physical proximity can agree on a key and any device outside a cer- tain distance gets nothing about the key. Compared with existi
Authentication and Key Agreement via Memorable PasswordAuthentication and Key Agreement • November 5th, 2007
This paper presents a new password authentication and key agreement protocol, AMP, based on the ampli ed password idea. The intrinsic problems with password authentica- tion are the password itself has low entropy and the password le is very hard to protect. We present the ampli ed password proof and the ampli ed password le for solving these problems. A party commits the high entropy information and ampli es her password with that information in the amplifed password proof. She never shows any informa- tion except that she knows it. Our ampli ed password proof idea is very similar to the zero-knowledge proof in that sense. We adds one more idea; the ampli ed password
Authentication and Key Agreement Protocols Preserving AnonymityAuthentication and Key Agreement • April 5th, 2006
Anonymity is a very important security feature in ad- dition to authentication and key agreement features in communication protocols. In this paper, we propose two authentication and key agreement (AKA) protocols: the AKA protocol with user anonymity (UAP) and the AKA protocol with user and server anonymity (USAP). The proposed protocols have the following advantages: first of all, they preserve anonymity, which is a security feature that was ignored in most of the previously proposed AKA protocols; secondly, they exploit the difference in capabil- ities between resource constrained clients and highly re- sourceful servers and thus are suitable for wireless applica- tions; thirdly, they resist known attacks; and finally, they perform better in terms of the number of messages and bits exchanged and computing time as compared to the previously proposed AKA protocols. For example, USAP preserves user and server anonymity, exchanges 3 mes- sages with 1920 bits in total, and requires only 2

Authentication And Key Agreement Based On Anonymous Identity For Peer-To-Peer CloudAuthentication and Key Agreement • July 22nd, 2022
Cross-cloud data migration is one of the prevailing challenges faced by mobile users, which is an essential process when users change their mobile phones to a different provider. However, due to the insufficient local storage and computational capabilities of the smart phones, it is often very difficult for users to backup all data from the original cloud servers to their mobile phones in order to further upload the downloaded data to the new cloud provider. To solve this problem, we propose an efficient data migration model between cloud providers and construct a mutual authentication and key agreement scheme based on elliptic curve certificate-free cryptography for peer-to peer cloud. The proposed scheme helps to develop trust between different cloud providers and lays a foundation for the realization of cross-cloud data migration. Mathematical verification and security correctness of our scheme is evaluated against notable existing schemes of data migration, which demonstrate that o
AUTHENTICATION AND KEY AGREEMENT BASED ON ANONYMOUS IDENTITY FOR PEERTO-PEER CLOUDAuthentication and Key Agreement • July 9th, 2021
Cross-cloud data migration is a major difficulty for mobile customers and is a necessary step when users turn their mobile phones into another provider. However, because smartphone's locally limited storage and computing capabilities, it is sometimes quite complicated to back all data on your mobile phone from the original cloud servers in order to upload the downloaded data further to a new cloud provider. In order to tackle this challenge, we offer an efficient data movement model between cloud providers and build a mutual authentication and key agreement system based on certificates-free elliptical curve cryptography for the peers of the cloud. The suggested system helps build trust between different cloud providers and provides a basis for cross-cloud data movement. Our scheme evaluates its mathematical verification and security correctness against significant current data migration strategies, showing that our scheme proposes an improved performance in terms of reducing both compu

An Efficient Authentication and Key Agreement Protocol in RFID SystemAuthentication and Key Agreement • August 16th, 2008
Abstract. Due to the very limited computing resource, storing space and electric power supply of tag, it is a great challenge for us to design a practical RFID protocol which is security, efficient and can be used in the low-cost tag. In 2007, He et al. proposed an authentication and key agreement protocol which is used in the process of communication be- tween the low-cost tag and reader. They also proved the security of the protocol through the extended strand space model. This paper presents a more efficient authentication and key agreement protocol for RFID system than He et al.’s protocol. Compare with He et al.’s protocol, the proposed protocol reduces the computational costs as well as protocol communication rounds to agree a shared session key between the reader and the tag.
