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 exist
AUTHENTICATION AND KEY AGREEMENT BASED ON ANONYMOUS IDENTITY FOR PEER-TO-PEER CLOUDAuthentication and Key Agreement • May 22nd, 2024
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
