The proliferation of medical internet of things (MIoT)-enabled medical devices and systems has completely transformed the healthcare industry. Widespread adoption of MIoT, however, raises major concerns about the privacy and access control of sensitive electronic health records (EHRs). In this paper, we propose a novel Cipher text Policy Attribute-Based Signcryption (CP-ABSC-MIoT)-based privacy-preserving and access-control scheme for EHR in MIoT. The goals of our scheme are the fine-grained control of access, confidentiality, authenticity, and privacy preservation of EHRs, and they are accomplished by combining the benefits of attribute-based encryption and digital signature. The proposed system enforces access policies according to the unique characteristics of authorized EHR users. Several security features, such as data confidentiality and authentication with efficient access control, are supported by the proposed scheme, which is built on the basis of bilinear pairing. The AVISPA tool is used to demonstrate the proposed scheme’s security against adversarial scenarios in the OFMC and Cl-AtSe models. As a result, the proposed scheme is better suited to be used in the MIoT environment for secure sharing of EHR.

In today’s rapidly evolving technological landscape, traditional pedagogical approaches often fall short in preparing engineering students for real-world challenges. This article examines a novel experiential learning (EL) initiative implemented for third-year BTech computer engineering students in a computer graphics and gaming (CGG) course. Unlike conventional instruction methods, our approach immersed students in the complete lifecycle of game development—from conceptualization through implementation to public presentation. Working in collaborative teams, participants developed original 2D games and animation narratives while mastering graphics programming techniques, animation tools, and appropriate AI resources. The culmination was a public exhibition where eighty-one student developers showcased their creations to peers, faculty, school students, and industry professionals. We gathered comprehensive feedback from fifty-four school student visitors and external evaluators, employing both qualitative and quantitative metrics to assess project quality and learning impact. Notably, several exceptional projects attracted industry attention, resulting in museum deployment opportunities and two-month internships for selected students. This article details our methodological framework, implementation process, outcome analysis, and the initiative’s tangible real-world impact, demonstrating how immersive, project-based learning (PBL) significantly enhances student engagement, technical proficiency, and professional readiness in engineering education.

The Indian Railway network is the world’s fourth largest, transporting millions of people every day. One of the most difficult challenges for travelers is crossing the overhead bridges or subways to reach the right platform. To make this experience more comfortable we have developed the automatic system termed Railway Platform Crossing Automatic Bridge (RPCAB) to connect two opposite platforms. Here, the fabricated metal frame bridge is moved using a pair of double acting hydraulically/ pneumatically actuated telescopic cylinders. After the train pulls out of the station, the bridge connects to the other side of the platform, allowing passengers to walk on the bridge to cross the tracks. The position sensors, alarms, audio/visual indicators, and actuators are all in sync with the train traffic signaling system and the master controller, a Programmable Logic Controller (PLC). To prevent any mishaps from happening, a comprehensive safety interlock system has been implemented, including position sensors, safety barricades, emergency alarms, and an audio-visual information system. The proposed mechanical bridge facilitates the passage for the passengers who are physically impaired, with heavy luggage, pregnant women, and the elderly persons to cross the platform. Additionally, it controls the congestion of passengers when the train has left the station. The proposed system is simulated using PLC simulator for testing, validation, and analysis of the system’s behavior in a simulated environment. The simulation results presented in this paper show how efficient and reliable the proposed design is. Prior to constructing a working prototype in real time, it is essential to put the system through a virtual environment. The results support the viability of applying the proposed design in real-world settings, which will improve both safety and efficiency at railway platform crossings.

The jigsaw method is a form of collaborative learning in which students work in small groups to thoroughly understand a topic and then teach it to their classmates. This study is conducted at a university with a student body that is demographically and racially representative of the institution. The primary goals of this research are to determine how the jigsaw approach affects students’ participation, collaboration, and critical thinking. This research will contribute to our understanding of how the jigsaw method can be used to improve the teaching of blockchain at the engineering undergraduate level. The research aims to benefit teachers, curriculum designers, and academic administrators by demonstrating the effects it has on students’ motivation and performance in the classroom. The findings will be used to enhance blockchain education at the engineering undergraduate level by informing the implementation and optimization of the jigsaw method.

The Distributed Denial of service attack is the most threatening attack to the current internet security. DDOS can be attempted by many different techniques but flooding is the easiest way of attempting it. In this paper we have proposed the dynamic bandwidth control framework which detects and defend DDOS attack very quickly and efficiently by using rate limiting mechanism. The proposed defense system is distributed in nature because it is deployed on all edge routers of the network. The proposed dynamic bandwidth control approach penalize the different routers with different rate limit valued based on current traffic at victim end and source end and the packet drop history. The routers sending aggressive traffic will be penalize with lower rate limit value and with moderate traffic will be penalize with higher rate limit value. The propose system is compare with existing distributed defense framework and implemented with existing network simulator NS2.The experimental results are showing that the proposed dynamic bandwidth control system perform better than the distributed framework.

The rapid development of smart renewable energy grids (SREGs) has resulted in a vast amount of data that requires efficient access control and secure mechanisms for sharing energy records among stakeholders. This paper proposes a novel approach called the identity‐based proxy signcryption‐based scheme for SREGs (ID‐PSC‐SREGs), which ensures the secure sharing of energy records in SREGs. The ID‐PSC‐SREG scheme integrates the benefits of signature and encryption techniques, merging them into a unified algorithm and providing a comprehensive solution for the confidentiality and authenticity of energy records. Extensive security analysis demonstrates that the scheme achieves provable security against adaptive chosen ciphertext attacks (IND‐ID‐PSC‐SREG‐CCA2) and existential unforgeability against adaptive chosen message attacks (EUF‐ID‐PSC‐SREG‐CMAs) under the decisional Diffie–Hellman problem. In order to further ascertain the security of the ID‐PSC‐SREG scheme, formal verification utilizing the automated validation of internet security protocols and applications (AVISPAs) is performed. The results confirm the scheme’s safety under the On‐the‐Fly Model‐Checker (OFMC) and Constraint Logic‐based Attack Searcher (CL‐AtSe).

The extension of digital competences in the ever-changing world of technology has transported global organizations new opportunities like never before. But this expansion has also flickered a dramatic surge in cybercrime, which carriages a huge problem that needs inventive replies. The current methods of cybercrime investigation are inadequate, predominantly when it comes to finding the source of attacks. While SSL safeguards secure data transmission, it does not offer forensic support, and the TCP/IP protocol suite does not form any protocols that are intended to be operative in cybercrime investigations. To rectify these difficulties, this paper proposes adding a forensic layer below the SSL layer. This novel feature consists of three protocols that reinforce user authentication and verification: IVAP, which is intended to brace the authentication and identification; Pro_DEC, which confirms that digital evidence is composed in a forensically comprehensive manner; and Cybercrime Attribution, which supports to attribute cybercrimes by tracking the source and path of data packets. The steadiness of court procedures amended by these protocols, which bid a specific toolbox for precise threat tracing and acknowledgement. Enhanced fact-finding capabilities and national safety are the main outcomes of this preventative approach to shore up cybersecurity and make systems tougher in the face of ever-changing cyber threats.

Due to real-time data sharing in the Internet of Medical Things (IoMT), the healthcare sector has evolved significantly in recent years. However, security breaches reveal incorrect authenti- cation and susceptible access during EHR distribution of EHRs among various stakeholders. Thus, a primary objective of the National Digital Health Mission (NDHM) is to employ cutting-edge technology to strengthen the security of electronic health records (EHRs) while safeguarding patient privacy. This paper proposes a signcryption with an identity-based authentication protocol based on Elliptic curve cryptography securing the transmission of medical records. The proposed protocol is designed based on bilinear pairing, and it supports several security features, including data confidentiality and au- thentication with effective key management. The proposed protocol is shown formally complete using BAN logic. Besides, our protocol is shown secure against potential attackers using the AVISPA under the OFMC and Cl-AtSe models. Nonetheless, the empirical analysis demonstrates that the proposed protocol outperforms the existing related schemes. Therefore, our proposed protocol is more suitable to be applied in the Internet of Medical Things (IoMT) environment.

In the realm of digital forensics, the establishment of robust standards for maintaining the integrity of digital evidence is of paramount importance. Addressing this concern, this study introduces a cutting-edge solution known as Identity-based Proxy Re-Encryption Chain of Custody (IR-PER-CoC). This novel protocol significantly enhances the chain of custody in digital forensics by safeguarding the secure transmission of encrypted evidence from the delegator to the delegatee through a process of re-encryption. Leveraging the power of bilinear pairing cryptography, the protocol incorporates a suite of security measures, ensuring its resilience against adaptively chosen identity and chosen plaintext attacks (IND-ID-PRE-CoC-CPA) under the Decisional Bilinear Diffie–Hellman (DBDH) assumption. To fortify its security posture further, extensive simulations within the AVISPA framework validate the protocol’s robustness, demonstrating its capacity to withstand attacks, as assessed by both the OFMC and Cl-AtSe models. Moreover, empirical evaluations affirm the protocol’s superiority over existing methods, underlining its efficacy in the management of the Chain of Custody in digital forensics. These compelling outcomes collectively establish the IR-PER-CoC protocol as a technologically advanced and practical solution for bolstering the integrity of digital evidence and the overall security of digital forensics investigations.

In the security domain, wide variety of signature schemes are available for providing confidentiality, Integrity and non-repudiation. Proxy signature schemes which are variant of digital signature found their importance in e-governance and finance domain for authority delegation. Role based delegation proposed in this research work is aimed for providing in roles rights in the signature form to the individual in the terms of proxy signature. Various proxy signature delegation schemes are studied and compared on the parameter’s security, efficiency and key management majorly. Forward secure proxy key generation and verification scheme Ro-De-PSA is proposed based on Elliptic curve cryptography (ECC). The correctness of the proposed algorithm is analysed using BAN logic and the security analysis is performed using AVISPA.
