LWEDM: Learning with error based secure mobile digital rights management system

Abstract

Mobile multimedia security is essential to ensure a secure communication in industries, businesses, and organizations. Mobile multimedia is a new concept for an enterprise, where organizations need to be secure. In the last decade, a number of anonymous authentication protocols have been designed based on factorization and discrete logarithm assumptions. Shor's algorithm solves a number‐theoretic assumption in polynomial time using postquantum computers that creates a trouble. However, learning with errors is an advanced hard assumption that cannot be solved by any known existing quantum algorithm. This inspires one to design an anonymous postquantum authentication protocol for the mobile digital rights management system. The protocol has been proved secure in a random oracle model under learning with errors assumption. Moreover, the article contributes an informal security discussion, an implementation using automated validation of internet security protocols and applications. The performance analysis ensures its efficiency even in the postquantum era.

On the security of ring learning with error‐based key exchange protocol against signal leakage attack

“…We have taken into account the recently published quantum safe cryptosystems for our study. During our study we identify Dharminder and Chandran 9 and Dharminder 10 are not safe against quantum attacks. These protocols do not achieve security against signal leakage attack (SLA) on the basis of our cryptanalysis.…”

“…We have analyzed Dharminder's LWE-based KEA protocol for mobile digital rights management systems. 10 The user registration phase of their protocol is shown in Table 1, and the complete mutual authentication structure is shown in Table 2. Although this scheme is efficient, simple, and functional for cellular devices in the post-quantum era, but it is susceptible to SLA.…”

“…Further, Ding et al 27 examined and advanced the work of Dabra et al 26 In 2020, Islam 28 proposed a lattice based two party key agreement protocol with the intractability of RLWE problem. In 2021, Dharminder 10 designed an anonymous postquantum authentication protocol for the mobile digital rights management system. Kumar and Garg 29 proposed an authentication protocol for satellite communication based on RLWE problem in 2022.…”

“…These protocols do not achieve security against signal leakage attack (SLA) on the basis of our cryptanalysis. Our contribution is as follows:Presented cryptanalysis on Dharminder and Chandran 9 and Dharminder 10 Identify the reason of attack and clearly specify why existing schemes do not achieve security against signal leakage, which provide guidelines for future construction to avoid these attacks. Analyze the computation complexity of existing schemes and presented comparative study over performance. …”

Design and Implementation of an Intelligent Online English Learning System Based on Mobile Internet Technology

“…In China, under the joint promotion of online education institutions and enterprises, course-teaching and tutorial-class style online learning platforms have become the mainstream form of online learning [13]. A variety of online learning platforms have sprung up one after another, such as MOOC, chuanke.com, and the mobile app of "Xuexitong" developed by Chaoxing, etc., and the corporation between online learning platforms, education institutions, and teachers has become a new mode of online education in China [14]. Such new mode has reformed the traditional education mode, broken temporal and spatial restraints, and enabled students to use their time fragments to learn at any time they want [15].…”
