![]() Hackers who apply this type of computing to their arsenal of attacks will be able to quickly break encryption algorithms widely used today. As a result, systems capable of breaking traditional math-based cryptographic algorithms are predicted to arrive within the next 5-10 years. ![]() For example, complex mathematical equations that take traditional computers months or even years to solve can be broken in moments by quantum computers running quantum algorithms like Shor’s algorithm. Unfortunately, they are also capable of generating new threats at unprecedented speed and scale. The rapid development of quantum computers promises to deliver powerful computer science capabilities that solve a wide range of critical, even lifesaving, computing problems that traditional computers simply cannot. This article focuses on post-quantum cryptography, quantum-safe certificates, and how enterprises can protect themselves as these risks become a reality. Quantum key distribution: The process of using quantum communication to establish a shared key between two trusted parties so that an untrusted eavesdropper cannot learn anything about that key.Quantum-safe cryptography: The development of cryptographic algorithms, also known as post-quantum cryptography, that are secure against an attack by a quantum computer and used in generating quantum-safe certificates.Two popular, yet distinctly different cryptographic applications that are under development using quantum properties include: While many areas of this science are conceptual rather than a reality today, several important applications where encryption systems intersect with quantum computing are essential to the immediate future of cybersecurity. ![]() Theoretically, this type of computer can aid the development of new, stronger, more efficient encryption systems that are impossible using existing, traditional computing and communication architectures. The broader application of quantum cryptography also includes the creation and execution of various cryptographic tasks using the unique capabilities and power of quantum computers. Quantum cryptography is a science that applies quantum mechanics principles to data encryption and data transmission so that data cannot be accessed by hackers – even by those malicious actors that have quantum computing of their own.
