QR Code Security
QR code security refers to the measures and practices implemented to ensure the integrity, authenticity, and safety of Quick Response (QR) codes. QR codes are two-dimensional barcodes that can store various types of information, such as website URLs, product details, or contact information. QR code security involves protecting against the generation or distribution of malicious QR codes that may lead to phishing websites, malware downloads, or unauthorised access. Users should be cautious when scanning QR codes from unknown or untrusted sources and use QR code scanning apps that provide security features and verify the content before execution.

Quantum Cryptography
Quantum cryptography, also known as quantum key distribution (QKD), is a cryptographic method that leverages the principles of quantum mechanics to secure communication channels. Quantum cryptography provides provable security against eavesdropping and interception by exploiting the fundamental properties of quantum mechanics, such as the uncertainty principle and the no-cloning theorem. QKD enables the generation and distribution of encryption keys with high security guarantees, ensuring the confidentiality and integrity of data transmitted over the network. Quantum cryptography is an emerging field that holds promise for future secure communication systems resistant to quantum computing attacks.
