PQShield publishes white paper series to educate business leaders on the quantum threat to information security PQShield, the cybersecurity company specialising in post-quantum cryptography, has today published a series of white papers explaining the quantum threat to information security and outlining the solutions that will help organisations to protect their sensitive information for the future. When full-scale quantum computers arrive, they will be able to break the public-key encryption widely relied on to protect sensitive data, accessing all digital information - past, present and future. Knowing the sheer scale of the quantum security threat, engineers and scientists around the world have been working to develop a new generation of encryption - post-quantum cryptography - that will enable organisations to protect their sensitive data now and for years to come.
