High Level Differences Between PQC and QKD

The threat of quantum computers breaking down modern cryptographic algorithms and exposing the confidential information of governments, corporations, and individuals is real. According to the National Security Memorandum released by the White House in May 2022, a “cryptanalytically relevant quantum computer (CRQC) could jeopardize civilian and military communications, undermine supervisory and control systems for critical […]

Patents, Intellectual Property Statements, and Post Quantum Cryptography

As the development of functional quantum computers by companies such as IBM, Intel, and Google advances, post-quantum cryptography (PQC) is becoming a necessity. The exceptionally high processing power of these computers can enable them to break down all modern cryptographic algorithms. To prevent this, more complex encryption and digital signature schemes must be developed and […]

Post Quantum Cryptography: Unpathed Frontiers of the Quantum Era

The central goal of cryptography is to ensure secure and confidential communication between multiple parties. Electro-mechanical encryption can be traced back to World War II when Nazi Germany used the Enigma machine to transmit sensitive military and diplomatic messages. In today’s digital world, cryptography is everywhere; account passwords, text messages, e-commerce, emails, and secure web-browsing […]

PQC – security concerns about Learning with Errors (LWE)?

Abstract It is well known that the Learning with Errors problem, together with its variations, represents a key ingredient for prospective quantum-resistant cryptographic algorithms due to its efficiency properties and good implementation properties, as is shown by the fact that several proposals for the NIST competition on post quantum cryptography rely on flavors of the […]
