Secure Communications and Quantum Cryptography Management

This technical report discusses the challenges and solutions related to secure communications in the context of quantum computing threats. It outlines the vulnerabilities of current public-key algorithms, such as RSA and ECDSA, to quantum attacks, necessitating a transition to post-quantum cryptography (PQC). The document details the concept of cryptographic agility, which is essential for organizations to adapt to evolving cryptographic standards and threats. It explains the importance of a decentralized cryptography deployment model and the difficulties associated with migrating to PQC. The report introduces QuSecure's QuProtect, a solution designed to facilitate this migration while maintaining operational continuity. It also addresses the need for updated cryptographic policies that align with current regulations and compliance frameworks, emphasizing the role of IT teams in implementing these policies effectively. The document highlights the significance of agility in cryptographic systems to ensure ongoing security against emerging threats.
