Quantum Computing, Artificial Intelligence and The Cyber Threat Landscape

Artificial intelligence, quantum computing and the laws of encryption

Key points…

+  Quantum computing took off in the early 90s and is now emerging as the next generation of computing. Operations that take hours and days, will happen in seconds with quantum power. With that technology, the scaling of computations goes up dramatically, to the point where the time needed for breaking traditional encryption would shrink to weeks, or maybe even minutes. This means breaking some of the foundational encryption we see in use today. The estimates for when QC will really take off range anywhere from 5 to 20 years. One thing we do know, however, is that QC has the potential to completely transform the cyber threat landscape.

China may be behind in raw quantum computing hardware, but they are making good headway on finding applications for quantum computing once it becomes a reality. While quantum computing is still years away from becoming a conventional technology, it is a tight arms race.

+  That said, quantum computing poses risks to some cryptography algorithms. For instance, public-key cryptographic algorithms, which are based on the discrete logarithm problem, elliptic curve logarithm problem, and integer factorization problem (RSA encryption) are susceptible to brute-force attacks using Shor’s algorithm. Whoever develops the quantum computers first would be able to break legacy encryption protecting historical information. Parallel to the development of quantum computing has been that of “post-quantum” or “quantum-resistant” cryptography to create encryption mechanisms that are resistant to quantum computing decryption capabilities. It remains to be seen whether these will achieve widespread adoption prior to quantum computers’ ability to trivialize existing encryption schemes.

+  While threat actors may use quantum computing to defeat some encryption algorithms, we expect that the adoption of quantum key distribution (QKD) will increase the secrecy of communication networks. The nature of quantum key generation and distribution guarantees communication systems’ security because the observation of a quantum-generated key will necessarily degrade or otherwise alter the key in a detectable fashion. As a result, we predict this will severely inhibit traffic interception schemes, as recipients would be able to identify messages that have been viewed prior to their receipt.
