In the realm of digital security, encryption plays a vital role in safeguarding sensitive information. For decades, the RSA encryption algorithm has been widely used and trusted for its effectiveness. However, with the rise of quantum computers, the robustness of RSA encryption has come under scrutiny. In this blog post, we will explore the fundamentals of RSA encryption and discuss why it is vulnerable to quantum computing.
Understanding RSA Encryption:
RSA encryption, named after its inventors Ron Rivest, Adi Shamir, and Leonard Adleman, is a widely adopted public-key encryption algorithm. It relies on the difficulty of factoring large numbers into their prime factors. The security of RSA encryption is based on the assumption that factoring large numbers is a computationally intensive task for classical computers.
Quantum Computing Threat:
Quantum computers, utilizing the principles of quantum mechanics, have the potential to revolutionize computing power. One of their most significant threats to classical encryption algorithms lies in their ability to perform Shor’s algorithm efficiently. Shor’s algorithm can factor large numbers exponentially faster than classical algorithms, posing a significant risk to RSA encryption.
Breaking RSA with Quantum Computers:
In RSA encryption, the public key consists of a product of two large prime numbers, while the private key relies on the knowledge of the prime factors. Shor’s algorithm can factorize these large numbers efficiently, thus compromising the security of RSA encryption. As quantum computers advance in power, they will be capable of breaking RSA encryption with ease.
To combat the vulnerability of RSA encryption to quantum computers, researchers are actively developing post-quantum cryptographic algorithms. These algorithms aim to withstand attacks from both classical and quantum computers. Promising alternatives include lattice-based, code-based, and multivariate cryptography, among others. The transition from RSA to post-quantum algorithms will require a careful and coordinated effort from organizations and service providers.
While RSA encryption has served as a robust cryptographic tool for several decades, the emergence of quantum computers poses a significant threat to its security. As the power of quantum computers continues to advance, the need for post-quantum cryptographic algorithms becomes increasingly urgent. Organizations and individuals must remain vigilant and proactive in adopting and implementing these new encryption methods to ensure the long-term security of their sensitive data in a quantum-powered future.

We at IronCAP™ have been trying to educate businesses and individuals that Q-day (the day the first quantum hack is publicly recognized) is around the corner and everybody needs to gear up. Nation states and governments are already at it, how about you? To learn more, visit www.ironcap.ca.
IronCAP™ is our latest innovation for the post-quantum cybersecurity. This patent-protected, post-quantum cryptographic system is based on the Goppa Code-based cryptographic technology. It has embedded our proprietary subclass of (L, G) making it not only more secured but also has faster cryptographic operations (key generation, encryption, decryption) than the traditional Goppa Code-based technology (McEliece). We are offering a live demonstration for the general public to try and experience the strength of IronCAP™ post-quantum encryption easily. To learn more, visit www.ironcap.ca.
