The CISO’s guide to accelerating quantum-safe readiness

Posted on by

Quantum computing presents both opportunities and challenges for the modern enterprise. While quantum computers are expected to help solve some of the world’s most complex problems, they also pose a risk to traditional cryptographic systems, particularly public-key encryption. To ensure their organization’s data remains secure now and in the future, chief information security officers (CISOs) […]

How does the SSL/TLS protocol determine if a certificate is expired or not?

Posted on by

I already tried googling but no luck. All search results always tell you how to check cert expiration manually, but that is not my question. Yes I can use OpenSSL for example, but what I am asking is how the SSL/TLS protocol does it, not h… Continue reading How does the SSL/TLS protocol determine if a certificate is expired or not?→

Cybersecurity trends: IBM’s predictions for 2024

Posted on by

From world events to the economy, 2023 was an unpredictable year. Cybersecurity didn’t stray far from this theme, delivering some unexpected twists. As organizations begin planning their security strategies for 2024, now is the time to look back on the year before and extrapolate what the future may hold. The year kicked off with Generative […]

Improving Shor’s Algorithm

Posted on by

We don’t have a useful quantum computer yet, but we do have quantum algorithms. Shor’s algorithm has the potential to factor large numbers faster than otherwise possible, which—if the run times are actually feasible—could break both the RSA and Diffie-Hellman public-key algorithms.

Now, computer scientist Oded Regev has a significant speed-up to Shor’s algorithm, at the cost of more storage.

Details are in this article. Here’s the result:

The improvement was profound. The number of elementary logical steps in the quantum part of Regev’s algorithm is proportional to …

Is it possible to securely use a remote service in a completely hostile network environment

Posted on by

A worldbuilding technical question!
I am an extremely evil power-mongering country government. There is a company S under my jurisdiction, physically located completely inside the borders. This company provides services worldwide, includin… Continue reading Is it possible to securely use a remote service in a completely hostile network environment→
