When quantum computing breaks through and is able to solve Shor’s algorithm in something more reasonable than 320,000 years, blockchain is in serious trouble.
For identities, would something like Key Event Receipt Infrastructure (KERI), be… Continue reading Quantum proofing blockchain with KERI? [closed]
The NATO Cyber Security Centre (NCSC) has successfully tested secure communication flows in a post-quantum world using a Virtual Private Network (VPN) provided by the United Kingdom-based company Post-Quantum. The NATO Cyber Security Centre, which is r… Continue reading Post-Quantum secures NATO’s communications for the quantum era
This thread is for how ssh-keygen relates to quantum computing attacks.
What are the strengths and weaknesses of the ssh-keygen algorithms as related to quantum computing, which from my understanding will be able to potentially crack them … Continue reading What ssh-keygen algorithm, or solutions, may be short-term future-proof effective for quantum computing attacks? [closed]
A wide range of organizations from defence to banking are preparing for ‘Y2Q’, the moment when a sufficiently developed quantum computer emerges that can break today’s encryption. As a trusted cyber security supplier to ultra high net worth individuals… Continue reading CDS partners with Post-Quantum to provide post-quantum encryption algorithms for super yachts
As we know, NIST PQC project is at its 3rd round, with draft standard expected to arrive in the next (few) year(s).
An unfortunate fact is that, we’re not seeing many signature schemes general-purpose enough (in the sense that, the size of… Continue reading SSL/TLS Forward secrecy with 2 KEM public keys
These days a lot of vendors are agressively marketing their Quantum Random Number Generators (QRNG), citing emerging/potential threat from quantum computers. I was wondering, are the existing state-of-the-art CSRNGs (hardware or software) … Continue reading Are "non-quantum" cryptographically secure random number generators vulnerable to quantum attacks? [closed]
Currently the entire "post-quantum security" relies on post-quantum cryptography only.
Why?
A quantum system is, at this moment, unpredictable, could this characteristic be an issue to security related problems? Why the current r… Continue reading Quantum security open challenges [closed]
I am using a custom Python build, with the liboqs-openssl which is encapsulating pq-algorithms. I generated the certificates using the provided dilithium2 algorithm and wanted to create a simple SSL connection with a Python client and serv… Continue reading Python SSL – No Shared Ciphers
Why are Leighton-Micali Signature Scheme (LMS) and eXtended Merkle Signature Scheme (XMSS) no candidates in the NIST Post-Quantum Cryptography Standardization process?
Both are mentioned in the final draft of Recommendation for Stateful Ha… Continue reading Why are LMS and XMSS no candidates in the Post-Quantum Cryptography Standardization process?
This question has been burning in the back of my head for the past few days, and a quick Google search doesn’t yield any usable results.
As the title suggests: What is the easiest-to-understand post-quantum asymmetric cryptographic algorit… Continue reading What is the simplest post-quantum asymmetric cryptographic algorithm?
