Pioneering Security with Post-Quantum Encryption
Zoom Video Communications, Inc. has once again set the benchmark for security in the Unified Communications as a Service (UCaaS) sector by announcing the global availability of post-quantum end-to-end encryption (E2EE) for Zoom Meetings. This pioneering security feature will soon extend to Zoom Phone and Zoom Rooms, further cementing Zoom’s commitment to safeguarding user data against emerging threats.
Addressing the “Harvest Now, Decrypt Later” Threat
As cyber threats evolve, so must the strategies to counteract them. One particularly concerning scenario is the “harvest now, decrypt later” attack, where adversaries capture encrypted network traffic with the intention of decrypting it once quantum computing becomes sufficiently advanced. Although quantum computers capable of such feats are not yet widely available, Zoom has proactively upgraded its encryption algorithms to withstand these potential future threats. By implementing post-quantum E2EE, Zoom ensures that user data remains secure against even the most advanced adversarial techniques.
How Post-Quantum E2EE Enhances Security
When users enable E2EE for their meetings, Zoom’s system ensures that only the participants have access to the encryption keys necessary for decrypting the data. This approach remains the same for both standard and post-quantum E2EE, with Zoom’s servers remaining unable to decipher the relayed encrypted data. To specifically combat “harvest now, decrypt later” attacks, Zoom’s post-quantum E2EE employs Kyber 768. This algorithm, being standardized by the National Institute of Standards and Technology (NIST) as the Module Lattice-based Key Encapsulation Mechanism (ML-KEM) in FIPS 203, is designed to be resilient against quantum decryption attempts.
Zoom’s Commitment to User Security
Since the introduction of end-to-end encryption for Zoom Meetings in 2020 and Zoom Phone in 2022, the adoption of these features by users has underscored the importance of robust security measures. Michael Adams, Chief Information Security Officer at Zoom, stated, “With the launch of post-quantum E2EE, we are doubling down on security and providing leading-edge features for users to help protect their data. At Zoom, we continuously adapt as the security threat landscape evolves, with the goal of keeping our users protected.”
Practical Applications and User Benefits
The introduction of post-quantum E2EE is not just a technological milestone but a practical enhancement for all Zoom users. For businesses, educational institutions, and governmental bodies, the need for secure communication channels is paramount. Post-quantum E2EE ensures that sensitive information shared over Zoom remains confidential, even in the face of future technological advancements in cyber threats.
Moreover, this enhancement is seamlessly integrated into the user experience. Enabling E2EE in Zoom Meetings is straightforward, ensuring that users do not face additional complexity in securing their communications. The promise of extending this feature to Zoom Phone and Zoom Rooms means that users will soon benefit from consistent security across all their communication platforms.
Looking Ahead: Future-Proofing Security
Zoom’s implementation of post-quantum E2EE highlights a forward-thinking approach to security, anticipating and mitigating threats that may arise with the advent of quantum computing. This proactive stance ensures that Zoom remains at the forefront of secure communications, providing users with a platform they can trust.

Conclusion
In an era where cyber threats are becoming increasingly sophisticated, Zoom’s introduction of post-quantum end-to-end encryption represents a significant leap forward in data security. By staying ahead of potential future threats, Zoom ensures that its users can communicate with peace of mind, knowing that their information is protected by cutting-edge encryption technology.
