Quantum internet is an innovative approach to secure communication. Quantum internet is the next revolution in technology that enables the devices to perform operations that are beyond the classical internet. Quantum internet with quantum cryptography is one of the best solutions for secure data communication. Quantum internet uses the fundamental laws of quantum physics, which make it secure against sophisticated network attacks. In this research, the authors described quantum cryptography, which enhances the secure transmission over quantum internet using cryptographic protocols. These protocols use random bits transformations, which prevent attackers to make out the patterns of random bits transformations. Also, they introduced the conceptual OSI model for quantum internet, which makes it easy to understand the working of the quantum internet at different layers. Quantum internet can be implemented in intelligence network, satellite communication, critical infrastructure, etc. This can mark a significant change in secure communication.

Bluetooth is frequently used as a file sharing platform, but with the advancement in technology, a new application Xender is now used for file sharing. Xender utilizes hotspot functionality in phones to share files. Apart from all the good reasons, Xender is also being used to share illicit and illegal material, and hence Xender forensics become inevitable. The paper is focused on Xender application, its working and forensics. We study how Xender logs generated can be used to analyze the file storage artifacts, logs, activities performed by sender and receiver. This has applicability in file sharing forensics.

Smartphone usage has increased in the recent past and has become an extension of the personal computer, so has the complexity of forensic investigation. Vital information on these devices makes them more critical especially when it is part of investigative evidences. The challenge here is the extraction of data, especially when the phone is logically or physically damaged. Chip-off is a niche technique, involving removal of Flash Memory chip with due sophistication, this then is subjected to direct extraction and analysis. Apple iPhones are robust and well locked; the study performed chip-off on model A1203 that revealed vital forensic evidences.
