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.

USA passes Quantum Computing Cybersecurity Preparedness Act
US President Joe Biden has signed the Quantum Computing Cybersecurity Preparedness Act into law. The law is designed to secure federal government systems and data against the threat of quantum-enabled data breaches. It sets out a number of obligations for federal agencies to prepare their migration to quantum-secure cryptography.
Apple to encrypt iCloud backups
Apple announced that it would fully encrypt backups of photos, chat histories, and most other sensitive user data in its cloud storage system worldwide. The US Federal Bureau of Investigations (FBI) responded with concerns over end-to-end encryption hindering their investigative capabilities, requesting ‘lawful access by design’ in the age of ‘security by design’.
Apple also stated that it would make iPhones compatible with physical security keys connected to the phone, allowing consumers to require them for access to their accounts from new devices. This is envisaged to be rolled out worldwide next year.
Communication app Signal is preparing for post-quantum cryptography
In an interview for TIME magazine, Signal’s President Meredith Whittaker confirmed that the communication app is preparing for post-quantum cryptography. The company is investing in research to update the Signal protocol for quantum safe cryptography. The ambition is to roll out the protocol before it becomes necessary, but it still will take some time to be finalised.
German Fraunhofer Institute and partners present demonstrated for quantum-safe electronic passport
The German Fraunhofer Institute, the German Federal Printing Bureau, and Infineon Technologies AG have presented the first demonstrator for an electronic passport that meets the security requirements of the quantum computing era.
The technology is based on a solution for contactless data transfer between the electronic passport and the border checkpoint terminal. The solution is based on a quantum computer-resistant version of the Extended Access Control (EAC) protocol and also secures biometric data during authentication.
The system was created under the joint research project ‘PoQuID’, funded by the German Federal Ministry for Economic Affairs and Climate Action (BMWK).
Post-Quantum Cryptography: Anticipating Threats and Preparing the Future
This report published by the European Union Agency for Cybersecurity (ENISA) discusses quantum-resistant cryptographic algorithms and proposes to design new cryptographic protocols as well as to integrate post-quantum systems into current protocols.
