The world-wide pandemic emerged due to severe-acute-respiratory-syndrome coronavirus-2 (SARS-CoV-2) causing viral respiratory disease (COVID-19). An insight into coronavirus drug, vaccine targets and their controlling agents are necessary and important for exploring new drugs and vaccines against the viral activities. Recent drug targets identified includes RNA-dependent-RNA polymerase (RdRp), papain-like proteases (PLpro), helicases, 3-chymotrypsin-like protease (3CLpro) are the proteins which are responsible for the viral replication and viral RNA synthesis. Most of the studies focussed on vaccine targets including spike protein (S), envelope protein (E), nucleocapsid protein (N) and membrane protein (M) to mitigate the proliferation and concentration of viral particles from infected one to others. Recent works revealed a strong awareness about the use of FDA approved drugs favipiravir, remdesivir, galidesivir, lopinavir, itraconazole, acyclovir and fleximer as repurposed drugs and few phytochemicals were also screened against the activity of viral enzymes to treat the complexity of the viral disease.

The Internet of Things (IoT) has brought about significant changes to various domains such as healthcare, transportation, and manufacturing. However, security remains a critical challenge in IoT due to the large number of connected devices with varying processing capabilities and memory constraints. Traditional cryptographic algorithms are not well-suited for IoT devices due to their high computational and memory requirements. Lightweight cryptography algorithms have emerged as a promising solution for securing IoT devices with limited resources. In this abstract, we provide an overview of lightweight cryptography algorithms for IoT, including their design principles, security properties, and performance evaluation.

Firmware attacks on IoT devices have become a growing concern in recent years. These attacks exploit vulnerabilities in the firmware, which is the low-level software that controls the hardware of the device, to gain access to sensitive data or control the device remotely. Firmware attacks are particularly dangerous because they can be difficult to detect and can allow attackers to maintain access to a device for an extended period of time. In this paper, we explore the silent threat of firmware attacks on connected devices and the potential consequences of a successful attack. We discuss the methods that attackers use to exploit firmware vulnerabilities and the impact these attacks can have on the security and privacy of users. We also provide recommendations for protecting against firmware attacks, including keeping firmware up to date, using strong passwords, and monitoring for suspicious activity on the network. By understanding the risks and taking proactive steps to protect against firmware attacks, users can help to ensure the security and integrity of their connected devices.

The convergence of the Internet of Things (IoT) and blockchain technology is revolutionizing the field of security. IoT devices are becoming increasingly prevalent in our daily lives, from smart homes to wearable technology, but they also pose a significant risk to cybersecurity. Blockchain technology offers a decentralized, tamper-proof network that can enhance the security of IoT devices. By creating secure identities, communication channels, and transactions, blockchain can protect IoT devices from potential cyber-attacks. This paper explores the advantages of using blockchain to enhance IoT security and highlights the potential of this technology to create a safer and more secure IoT ecosystem
