• “The time needed to factor an RSA integer is the same order as the time needed to use that same integer as modulus for a single RSA encryption.   In other words, it takes no more time to break RSA on a quantum computer (up to a multiplicative constant) than to use it legitimately on a classical computer.”

  • "One should not assume that stakeholders do not care about their security merely because they do not understand the consequences of certain actions. The perception of risk can vary significantly from actual risk and, in the short term, convenience may lead some early adopters to make hazardous decisions."

  • "First and foremost, there is no proper excuse for continued use of a broken cryptographic primitive (MD5) when sufficiently strong alternatives are readily available, for example SHA-2. Secondly, there is no substitute for security awareness." ... "Advice from experts should be taken seriously and early in the process. In this case, MD5 should have been phased out soon after 2004."

Abstract: Digital signatures have become a key technology for making the Internet and other IT infrastructures secure. But in 1994 Peter Shor showed that quantum computers can break all digital signature schemes that are used today and in 2001 Chuang and his coworkers implemented Shor’s algorithm for the first time on a 7-qubit NMR quantum computer. This paper studies the question: What kind of digital signature algorithms are still secure in the age of quantum computers?
Quote: “There is a good chance that large quantum computers can be built within the next 20 years.  This would be a nightmare for IT security if there are no fully developed, implemented, and standardized post-quantum signature schemes.”
