“…One-time pad is an encryption method in classical cryptography and has been reported by Shannon [ 10 ] to be theoretically unbreakable. Recent implementations of OTP, such as those of [ 11 , 12 , 13 ], served as references for the implementation of our own proposed key update mechanism in which we aimed to automatically execute both OTP (for changing password) and one-time pad (for nonrepeating key) in IoT devices as a network communication pair, namely D-OTP.…”

“…Most repeating keys, such as that of [ 33 ], have been developed on the basis of the Fisher–Yates shuffle algorithm [ 34 ]. However, this method places a heavy burden on computing performance for generating high entropy random numbers, and providing nonrepeating checks through the method requires a large amount of memory access [ 11 ]. Accordingly, we address this concern in our proposed design.…”

The ecosystem for an Internet of Things (IoT) generally comprises endpoint clients, network devices, and cloud servers. Thus, data transfers within the network present multiple security concerns. The recent boom in IoT applications has accelerated the need for a network infrastructure that provides timely and safe information exchange services. A shortcoming of many existing networks is the use of static key authentication. To enable the use of automatic key update mechanisms in IoT devices and enhance security in lightweight machine-to-machine (M2M) communications, we propose a key update mechanism, namely, double OTP (D-OTP), which combines both one-time password (OTP) and one-time pad to achieve an IoT ecosystem with theoretically unbreakable security. The proposed D-OTP was implemented into the Constrained Application Protocol (CoAP) through the commonly used libcoap library. The experimental results revealed that an additional 8.93% latency overhead was required to obtain an unbreakable guarantee of data transfers in 100 CoAP communication sessions.

“…The communication efficacy is examined, and it is observed that the channel achieves 152 bps as a maximum rate of transmission. A new method that utilises a combination of both the signatures as well as the pronounced name utterances (Malikovich et al, 2019) is proposed to authenticate the users. Here, the dynamic features of digital signatures are extracted for authentication rather than the traditional signature verification methodology.…”

Two-Factor Authentication (2FA) is a new buzzword in the Information Security world. Big companies that used passwords as an authentication mechanism now have started transitioning to 2FA. One form of two factor authentication is known as One-Time Password (OTP). In today’s time, there is a lack of a secure multi-factor authentication platform which is also user friendly. In all the major 2FA platforms that exist today, the user has to manually enter the OTP from their phone or email. This problem is further amplified by delays in transmission of OTP via email or SMS. There has also been an increase in the number of botnets that scan large networks and try to an open and vulnerable ports on cloud hosting networks. An easy-to-use port security solution is not available. This research work aims to create a secure, proof-of-concept implementation of a modern and opinionated two factor authentication system based on Near Sound Data Transfer (NSDT) technology enabling contactless secure transmission of Time-Based One-Time Password (TOTP).

“…Furthermore, the application of OTPs extends beyond traditional online transactions to domains such as land record management and ecommerce. [6] proposes the use of OTPs to enhance security in land record management systems, while [7][8][9] introduces an improved OTP system for ecommerce, addressing vulnerabilities such as denial-of-service attacks and phishing attempts.…”

In the realm of contemporary digital security, this study focuses on enhancing Secure OTP Management. The Alphabetical ID system is a pivotal solution to bolster security and streamline user authentication. It strategically displays three alphabetic characters in both the generated OTP sent to the user and the interface for OTP input. This design empowers users to identify the latest OTP among received codes, addressing the dilemma of consecutive OTPs causing confusion and potential access denial. The Alphabetical ID system revolutionizes identification protocols, significantly reducing the likelihood of unauthorized access. This heightened identification capability serves as a robust safeguard for sensitive data and reinforces the integrity of digital transactions. The synergy between the Alphabetical ID system and the conventional OTP process marks a paradigm shifts in user authentication, achieving an optimal balance between user experience and identification precision. As businesses transition towards digitization and online interactions, the Alphabetical ID system emerges as a pioneering leap, offering a reliable shield against unauthorized access and catalyzing fortified digital security. This inventive solution stands as a pragmatic answer to the challenge of identification in OTP management, culminating in an elegant fusion of simplicity and efficacy. The proposed Alphabetical ID system is poised to redefine the landscape of Secure OTP Management by placing a heightened emphasis on user-friendly identification mechanisms within the broader context of digital security.
