A framework of Iso-ID-Based PKC generated on IIF and DIDLP Ajay Thatere, Ashish Jirapure, Praveen Kumar Dhankar, Akshaykumar Meshram, Rupesh Pohane, Sumit Chellani Indiscon 2025 IEEE 6th India Council International Subsections Conference Proceedings, 2025 Shamir [1] proposed the idea of an identity-based cryptographic framework in 1984, where users are required to authenticate themselves at a key authentication center (KAC) before becoming part of an open network. After a user is verified, the key authentication center (KAC) issues a secret key to them. To initiate communication with another user, one simply needs the recipient’s identity and the KAC’s public key. This system framework eliminates the need for a public key directory. Nevertheless, Shamir was unable to develop a complete identity-based cryptosystem and was only able to create an identity-based digital signature scheme. This paper presents an isoidentity-based isocryptosystem that relies on the hardness of the isointeger factorization and double isodiscrete logarithm problems. We also examine the framework’s resilience against collusion among multiple entities and demonstrate how it can lead to an additional secure framework.
IIFP and IDLP based Public Key Isocryptosystem Akshaykumar Meshram, Ajay Thatere, Praveen Kumar Dhankar, Rupesh Pohane, Adesh Meshram, Sumit Chellani 2025 International Conference on Intelligent and Secure Engineering Solutions Cises 2025, 2025 The majority of existing cryptosystems rely on a single cryptographic assumption, such as the computational hardness of the integer factorization or discrete logarithm problems. Although these assumptions are presently regarded as secure, there is always the possibility that future advancements may lead to efficient algorithms capable of breaking one or more of them. The likelihood of multiple cryptographic assumptions being compromised at the same time is extremely low. Therefore, building cryptosystems on more than one assumption significantly strengthens security. K.S. McCauley [1] was the first to propose a key distribution system that relies on two distinct and independently hard problems. In his design, the security parameters for the two underlying assumptions differ significantly in size. The modulus required to ensure adequate security for one assumption is excessively large when applied to the other. The resulting drawbacks include: (1) a larger public key size compared to the traditional Diffie-Hellman key exchange, and (2) a higher computational cost. This paper introduces a public key encryption scheme built upon two hard problems: the isointeger factorization problem and the isodiscrete logarithm problem with dual isoexponents. To retrieve the original plaintext from the ciphertext, an adversary must simultaneously solve both the isointeger factorization and isodiscrete logarithm problems. This dual requirement significantly strengthens the security of the scheme. Furthermore, the proposed system is designed for efficiency, as both encryption and decryption processes involve only a minimal number of computational steps.
Design of ID-Based Public Key Isocryptosystem using DIDLP for Communication Ajay Thatere, Praveen Kumar Dhankar, Akshaykumar Meshram, Ashish Jirapure, Prateek Verma, Adesh Meshram 2025 IEEE International Conference on Computer Electronics Electrical Engineering and their Applications Ic2e3 2025, 2025 In 1984, the structure of an identity-based cryptosystem presented by Shamir [1]. In this approach, applicant must first run into key verification center (KVC) to verify their identity prior to connection an intercommunication system. Once authenticated, the KVC issues a secret key to the applicant. This structure allows applicant to intercommunication with one another applying only their "identity" and the universal key of the KVC, without requiring a universal file. Whereas Shamir's structure establish the foundation, he was inadequate to develop an entirely operative identity-based cryptosystem and rather created an ID-builted signature structure. In this article, we design an ID-built isocryptosystem using double isodiscrete logarithm problem. We also address the security of this structure against potential conspiracies involving multiple entities and analyse how to improve its overall security.
New Secure Password-based Authentication Procedure using Chebyshev Chaotic Maps Akshaykumar Meshram, N. M. Wazalwar, Chandrashekhar Meshram 2024 IEEE International Conference on Interdisciplinary Approaches in Technology and Management for Social Innovation Iatmsi 2024, 2024 Protecting public keys from unauthorized access is crucial in public key cryptosystems (PKC). Typically, password authentication methods must have at a minimum one institution to verify both public and private keys. The aim of this paper is to introduce a new, efficient password authentication method that's established on Chebyshev chaotic maps over Galois fields, marking a significant advancement in cryptographic security. Chebyshev chaotic maps are renowned for their sensitive dependence on fundamental circumstances and complex dynamics, making them ideal for enhancing password security. Through a comprehensive analysis of Chebyshev map theory and its application in generating unpredictable sequences, we developed an authentication architecture that not only improves security but also maintains user convenience. This proposed method offers robust security while maintaining a straightforward authentication process.
Explicit finite difference approach on multi-dimensional wave equation with constant propagation Malabika Adak, Akshaykumar Meshram, Anirban Mandal Recent Advances in Materials Manufacturing and Machine Learning, 2024 Different types of wave motion like light wave motion, sound wave motion, water wave motion and seismic wave motion arises in the field of vibrating string (musical instrument), electromagnetic field and fluid flow etc. Wave equation is a second-order linear hyperbolic partial differential equation (PDE). In engineering and physical science problems, solution of partial differential equations with complicated boundary condition (BCS) as well as irregular domain is a challenging work particularly with analytical method. Therefore, numerical method is one of the best choices to solve the boundary value problems (BVP) involving partial differential equation and suitable boundary conditions in more efficient way. In present study, one- and two-dimensional wave equations have been considered with constant propagation for solving BVP using explicit finite difference method (FDM). To illustrate error calculation, stability and convergence, two examples have been considered. Numerical solutions have been verified with analytical solution to test the accuracy and subsequently error has been calculated at each node for different mesh grid size in the direction of space and time. The numerical results for very small mesh grid size and small-time space will give the better accuracy. In this study two different mesh size along with space and two different mesh size along with time have been taken to verify the accuracy of numerical technique. While comparing with existing analytical solution it is observed that the percentage error for present solution technique is within the range of 7.45% for average mesh size. In case of finer mesh and small time step the error is further reduced to 4.16 to 5.84 %.
Face Recognition under Occlusion: An efficient Handcrafted Feature & SVM based Approach Ajay Thatere, Akshaykumar Meshram, Prateek Verma, Ashish Jirapure 2024 IEEE International Conference on Interdisciplinary Approaches in Technology and Management for Social Innovation Iatmsi 2024, 2024 Biometric-based recognition systems have been consistent matter of research and abundant contributions can be seen in different biometric areas. The growing artifacts in face biometrics in terms of occlusions have been a challenge and fooled the best face recognition system. The increased occlusion over the face had drastically reduced the chances of accurate detection. The article present an effective handcrafted feature based machine learning approach for face biometric recognition over CelebA dataset. The proposed system is able to extract prominent quality features from the uncovered region of the pose aligned and background cluttered face regions. The system overrule the need for augmentation for the unbalance dataset and performed better for low samples. The classification accuracy over 100 celebrities with distinct number of samples was found to be 98%.
Remote Monitoring of Hazardous Environment at Mining Sites Using LoRa Network Asfar H. Siddiqui, Anup Ranade, Akshaykumar Meshram, Vinod Waiker 2024 3rd International Conference for Innovation in Technology Inocon 2024, 2024 Mining sites are considered one of the most dangerous work environments due to the presence of hazardous gases. Workers are always at risk of being exposed to toxic and explosive gases such as methane (CH4) and carbon monoxide (CO). Therefore, it is crucial to monitor these gases and other environmental parameters like temperature and humidity in real-time to prevent any potential risks to human life and the environment. Although generic IoT networks are very much capable of monitoring hazardous gases from a mining site but, given the harsh environment of a mining site and being always at remote areas, a stable internet connection cannot be expected. In this study we will be making use of LoRa network, which is a wireless technology that has gained popularity in the field of remote monitoring in the recent years. LoRa operates on a low-power, wide-area network that allows data transmission over long distances without the requirement of internet. This makes it ideal for mining sites where the distance between the control room and the mineshaft can be several kilometers. We will be discussing the implementation of one sensing node to be installed in the vicinity of the mining site and would be responsible for sensing all the information and transmitting the same securely using its integrated LoRa module, and one central node which will be installed in the control room, which will be responsible for receiving the data transmitted by the sensing node, analyzing it, displaying it and generating alert if any value seems to be rising or falling into a hazardous level.
An Improvement of ID-Based IPKC Utilizing DIDLP Akshaykumar Meshram, Praveen Kumar Dhankar, Rupesh Pohane, Ajay Thatere, Asfar H. Siddiqui, Monali G. Dhote 2024 International Conference on Artificial Intelligence and Quantum Computation Based Sensor Applications Icaiqsa 2024 Proceedings, 2024 The identity-based cryptosystem ($\\mathfrak{J D}\\mathcal{C}$) framework was proposed by Shamir [1] in 1984. Within this framework, consumers is required to inquiry a key authentication center ($\\mathcal{K} \\mathcal{A C}$) to confirm their identity prior to accessing a transmission network. Once the verification is complete, the $\\mathcal{K} \\mathcal{A C}$ provides the consumer with a classified key. To communicate, a consumer simply must to recognize the “identity” of the other party and the communal key of the $\\mathcal{K} \\mathcal{A C}$, removing the necessity for a communal key directory. Although Shamir was unable to create a practical identity-based cryptosystem, he successfully developed a $\\mathfrak{J} \\mathfrak{D}$ signature technique. Subsequently, Meshram and Agrawal [2] introduced a $\\mathfrak{J} \\mathfrak{D}$ cryptosystem that is grounded in the double discrete logarithm problem, utilizing a communal key system that also relies on this problem. In this paper, we suggest enhancements to the $\\mathfrak{J} \\mathfrak{D}$ cryptosystem that is established on the double isodiscrete logarithm problem. We assess the system's preservation in the context of possible collusion between certain parties and illustrate opportunities for improving its overall security.

It's able to do that through integrating a technology offshoot which is the use of an Arduino Nano controller, ultrasonic sensors, and a 360-degree robot rotator. The sensors are tuned with a ultrasonic sound, that allow minute detection and presence of any threats within given distances. The identification of this system results in the instantiation of a countermeasure which is responsible for a speedy response. The design consists of power efficient operation, note specifically by the power management, and uninterrupted move via an exact motor option control. To guarantee the usability interface is displayed in LCD monitor of the machine. Real-time information is also shown on LCD display of the machine. Furthermore, the place of security functionally serves as a defense system from unauthorized access. This newly designed defense mechanism with fine component integration and exhaustive evaluation demonstrates remarkable importance for a dramatic shift in security infrastructure, which requires constant upgrading as advanced threats emerge.
