What is the purpose of quantum key distribution in the field of cybersecurity?
Quantum key distribution (QKD) serves a crucial purpose in the field of cybersecurity by providing a secure method for distributing cryptographic keys. Traditional cryptographic systems rely on mathematical algorithms, which can be vulnerable to attacks from increasingly powerful computers and algorithms. In contrast, QKD leverages the principles of quantum mechanics to establish a secure communication
What is the role of the secure enclave in mobile device security, particularly in user authentication?
The secure enclave plays a crucial role in mobile device security, particularly in user authentication. It is a dedicated hardware component found in modern mobile devices that provides a secure environment for sensitive operations, such as cryptographic key generation and storage, biometric data processing, and secure user authentication. This enclave is designed to be isolated
