Existing public-key cryptography is based on the difficulty of factoring and the difficulty of calculating elliptic curve discrete logarithms. Post-quantum cryptography (sometimes referred to as quantum-proof, quantum-safe or quantum-resistant) refers to cryptographic algorithms (usually public-key algorithms) that are thought to be secure against an attack by a quantum computer. The private communication of individuals and organizations is protected online by cryptography. These post-quantum cryptography algorithms are more complex than our current algorithms, and we at Rambus believe a revolution, rather than an evolution, of these existing algorithms is needed. Additional information, protocol integrations, and related releases can be found on those sites. In July, NIST released a report on the second round of their Post-Quantum Cryptography Standardization Process. As you noted, changing cryptographic algorithms is a challenge, and we expect that to be the case for the change to quantum-resistant algorithms. According to the article “Post-Quantum Cryptography: A Ten-Year Market and Technology Forecast” from Research and Markets, “many more individuals with purchasing authority are expected … We are also working to integrate each with common internet protocols so that we can test and further tune performance. Each proposal has different strengths and weaknesses, and each is built upon a different mathematical “hard problem.” Each may be appropriate for different scenarios where different trade-offs regarding performance and key size are preferred. NIST standardization of post-quantum cryptography will likely provide similar benefits. Picnic is a public-key digital signature algorithm, based on a zero-knowledge proof system and symmetric key primitives. Post-quantum cryptography is the cryptographic algorithms that are believed to be secure against an attack by such a quantum computer. Pursuing multiple candidates is also appropriate as the post-quantum cryptography field is young, and many years of cryptanalysis are needed to determine whether any post-quantum proposal is secure.
