I know this might sound counter-intuitive, but is it possible to configure gpg to store public keys in encrypted state on disks? Such that when encrypting a message to someone, user would be asked to first enter a passphrase to decrypt rec… Continue reading Does gpg support storing public keys in encrypted state?
If we talk about the security of public key encryption in Regev’s lwe system, if attacker would have knowledge of (u,u’)[u=Ar, u’=b^tr + µ q/2, r={0,1}^m] and b, then value of r in u’ can be guessed easily by the knowledge of u and A and s… Continue reading Regev’s learning with error [migrated]
I wrote an article on the impacts of sufficiently capable quantum computers on password strength and attacks.
The basic premise is that Grover’s algorithm halves the protective strength of password hashes and passwords, plus any additional… Continue reading Impact of quantum computers on password security [closed]
I would like to preface this with the information that I am clearly not well versed in crypto, so my understand so far may not be accurate.
CISA recently published an advisory Preparing Critical Infrastructure for Post-Quantum Cryptography… Continue reading Will the public-key cryptosystem change in a post-quantum state?
I already have experience with quantum computing and the mathematics behind it. I also know the quantum cryptography side e.g. BB84, etc.
I now want to move on to post-quantum cryptography and am therefore looking for suitable sources. Fav… Continue reading Sources for post quantum cryptography [migrated]
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
