DARPA announces new investment to protect systems from post-quantum cryptography

The Defense Advanced Research Projects Agency (DARPA) announced a multimillion-dollar contract with Duality Technologies, a firm specialising in homomorphic encryption designed to withstand quantum computing attacks. It does so through higher dimensions of security and more complex encryption keys compared to classical measures. In addition to being post-quantum, homomorphic encryption can be used to protect data when in use. This is critical because oftentimes, encryption is deployed to protect the material from a storage site to a user while in transit. By serving as an end-to-end encryption style, sensitive information is less vulnerable to attack.
