HomeChain
Background
- (IoT) Current Status
- Question secure and efficient remote user authentication solution.
- existing solutions a single-server architecture
- critical challenges providing regulation of behaviors and privacy protection of access policy)
- In this article novel secure mutual authentication system integrates blockchain
Introduction
home gateway provides network access between local area network (LAN) hosts to a wide area network (WAN) (like the Internet) via a modem. IP port
remotely communicate can be targeted and subject to exploitation.
The information from any single device may not be deemed sensitive
remote authentication approaches.
- password-based authentication. (limitations)
- Lack of Privacy and Anonymity
- Lack of Completeness and Confidentiality
- One-time password (OTP) authentication
- password-based authentication. (limitations)
Remote user authentication schemes based on smart cards [11] have also been widely used in applications involving remote user login, Web access, and other online services, due to their efficiency, convenience, and low computational cost.
blockchain-based authentications a more secure, reliable and convenient IoT systems
- limitation : the user behaviors cannot be effectively regulated .
- all the request transactions or access policy are in plaintext, which can be collected to statistically analyze user daily life, and thus, compromising user privacy.
- Contributions: To further provide traceability and privacy protection of access policy, we integrate both blockchain and group signature
- Organization: organize the reminder of this article as follows. Section II reviews the current blockchain-based smart home systems.
