PUF-Assisted Lightweight Group Authentication and Key Agreement Protocol in Smart Home

Abstract

Various IoT-based applications such as smart home, intelligent medical, and VANETs have been put into practical utilization. The smart home is one of the most concerned environments, allowing users to access and control smart devices via the public network remotely. The smart home can provide many intelligent services for users through these smart devices. To securely access devices and obtain collected data over the public network, multifactor authentication protocols for smart home have gained wide attention. However, most of these protocols cannot withstand impersonation attack, smart device lost attack, privileged-insider attack, smart card lost attack, and so on. Besides, high communication and computational costs weaken the system performance, which leads to most authentication protocols are not suitable for resource-constrained smart devices. To mitigate the aforementioned drawbacks, we proposed a PUF-assisted lightweight group authentication and key agreement protocol to implement secure access to multiple devices in the smart home simultaneously using the Chinese Remainder Theorem and secret sharing technique. Our protocol also utilizes physical unclonable function (PUF) and fuzzy extractor technique to extract the digital fingerprint of the smart devices, which can uniquely validate smart devices and protect the secrets stored in their memory. Our protocol can support various security features and withstand the many well-known attacks in the smart home. The performance analysis indicates that the proposed protocol can efficiently reduce communication/computational costs when the user simultaneously accesses multiple devices.

A Secure and Anonymous User Authentication Scheme for IoT-Enabled Smart Home Environments Using PUF

“…They asserted that MITM and tampering attacks are powerless against their scheme due to the proposed scheme performs mutual authentication based on the secret key generated by the PUF response. Xia et al [26] proposed a PUF-assisted group authentication scheme for the smart home that establishes a group session key between the home user and the home device by utilizing the chinese remainder theorem. Although their schemes [24]- [26] resist device capture attack utilizing PUF, they does not consider the verifier stolen attack, which can compromise all user communications by exploiting the verification table stored on the gateway.…”

“…In this section, we estimate the computational consumption and communication cost to evaluate the performance of the proposed authentication scheme. Furthermore, we compare the security functionality of our scheme with related authentication schemes [10], [19], [21]- [26].…”

“…We denote the consumption time of one-way hash function, fuzzy extractor, elliptic curve scalar multiplication, PUF, and symmetric cryptography operation as T h , T f , T mul , T p and T s , respectively. According to [26], each time is defined as T h = 0.0026ms, T f = 1.989ms, T mul = 1.989ms, T p = 0.12ms and T s = 0.00325ms. Table 4 compares the computaional consumption of our scheme with the existing related schemes.…”

Group Security Authentication and Key Agreement Protocol Built by Elliptic Curve Diffie Hellman Key Exchange for LTE Military Grade Communication

“…Several group AKA methods have been presented to achieve the aims of the mutual AKA between the group members and their network, whether used for group mobile authentication or machine type devices (MTDs) authentication. Privacy preservation and network overhead reduction are the most important aims for this type of communication [12]. This section presents a summary of the available group-AKA protocols.…”

Light Weight Deep Learning Algorithm for Voice Call Quality of Services (Qos) in Cellular Communication

“…When using GPRS technology, mobile phones are assigned IP addresses over the Internet, which in most cases are not unique. Edge technology is the next step in the evolution of GPRS technology (improved data rates for GSM evolution, faster data transfer for GSM development) [17][18][19]. In this technology, new information encoding schemes have been used compared to GPRS, and the error handling algorithm has been changed (incorrectly sent packets are not sent back, only information for their recovery is sent) [20].…”
