Embodiment Construction

[0056] The authentication communication method in a smart home of the present invention includes the following entities: a user, a server, a home gateway, and a home smart device. Including the following steps:

[0057] (1) System settings

[0058] In the system setting stage, the trusted entity (TA) generates system parameters params, and sends them to the home gateway and home smart devices offline. The generated system parameters are used for subsequent mutual authentication between the home gateway and the home smart device. We assume that the home gateway is trusted, so we let the home gateway play the role of TA. The specific steps are as follows:

[0059] • Choose ε as the difficulty of the puzzle.

[0060] • Choose ΔT as an upper bound on the message round-trip time.

[0061] • Choose H(*) as the hash function, and the output of this function is k bits.

[0062] · Select m as the number of elements in the Nonce.

[0063] TA distributes params=(∈,ΔT,H(*),m) to th...

Abstract

The invention discloses an authentication protocol in a smart home based on HLC and hash collision puzzles. The protocol includes: system setting, command message initialization, and mutual authentication. Aiming at the problem that devices in smart homes may be tampered with and attacked by other malicious devices, this protocol proposes a smart home authentication protocol, which constructs a low-computational-cost protocol to resist attackers or malicious home smart devices. The invention satisfies the characteristics of high efficiency, robustness and the like.

Description

technical field [0001] The invention belongs to the fields of smart home and information security, and in particular relates to an authentication communication method in a smart home based on HLC and hash collision puzzles. Background technique [0002] A smart home is a home that incorporates advanced automation systems to provide residents with sophisticated monitoring and control over building functions. A smart home can control lighting, temperature, multimedia, windows and doors, and many other functions. Smart homes use home automation technology to provide homeowners with intelligent feedback and information by monitoring many aspects of the home. Due to the superiority of smart homes, the commercial market for smart homes is also growing. With the further advancement of the interconnection and interoperability of home smart products, more explosive products are expected to appear in the future, which will promote the stable development of the overall smart home mar...
