Digital Signature

Today’s world is a digital world. A place of online meetings, virtual conferences, cloud-stored documents, and… digital signatures.

NIST’s Standardisation of PQC

In one of the previous blogs and on a recent PQC webinar we have discussed the public-key cryptography’s vulnerability to quantum attacks, specifically to attacks relying on Shor’s algorithm.

Zerologon Vulnerability

In September 2020 Secura published an article disclosing a vulnerability in Windows Server (all known versions) Netlogon Remote Protocol. This vulnerability is known as CVE-2020-1472 or more commonly, Zerologon.

Entropy – From Pseudo Randomness to Quantum RNGs

What is entropy and why do we need it in security and cryptographic systems?

Data Security and Encryption

The number of data breaches and security threats has been steadily increasing for years.

Coexistence of Blockchain and HSM

Blockchain is a system of recording information that makes it impossible to change, cheat or hack the system.

What Are the Threats of Quantum Computing?

In the previous blogs we have briefly touched upon how resistant symmetric and asymmetric cryptography are against quantum attacks. Here we discuss the topic in more depth.

Utimaco Atalla AT1000 Payment HSM

Utimaco successfully completed its acquisition of the Atalla payment Hardware Security Module (HSM) and Enterprise Secure Key Manager (ESKM) product lines from Micro Focus in November 2018. This strategic acquisition has positioned Utimaco as the second-largest hardware security module (HSM) manufacturer in the world and has createed the most comprehensive HSM offering on the market.

What is Asymmetric Cryptography and How Does It Work?

We can roughly divide encryption algorithms into symmetric and asymmetric ones. Symmetric ones have a longer history. It can be said that they have over 2000 years of history and development. The concept of asymmetric or public-key cryptography, on the other hand, was developed in 1970s and first publicly published in 1977 by Whitfield Diffie and Martin Hellman, researchers at Stanford University.

What is Symmetric Cryptography and How Does It Work?

When talking about symmetric cryptography we have in mind cryptographic algorithms enabling communication between a sender and a receiver. Both of them use the same cryptographic key for encryption and decryption.
