The adoption of post‑quantum cryptography is cybersecurity's most urgent priority

Post-quantum cryptography (PQC) is a new generation of cryptographic algorithms designed to remain secure even against quantum computers.

Many current systems rely on mathematical problems that are hard for classical computers: factoring large numbers (RSA) and the discrete logarithm (ECC and Diffie-Hellman). A sufficiently powerful quantum computer solves them with Shor's algorithm, breaking the cryptography that protects the internet today.

It is the moment when a quantum computer will be able to break today's public-key cryptography. Google has marked 2029 as the year of the definitive cryptographic break: the transition must start today.

It is an attack already underway: adversaries capture encrypted information today to store it and decrypt it once quantum technology is powerful enough. Long-lived data (financial, clinical, government) is already at risk.

The Cryptography Bill of Materials is the organization's cryptographic inventory: how many RSA keys exist, where they are and which application depends on them. It is the first step CISA and NIST require before touching a single algorithm.

Post-quantum cryptography (PQC) is a new generation of cryptographic algorithms designed to remain secure even against quantum computers.

Why is it needed? Many current systems rely on mathematical problems that are hard for ordinary computers:

• Factoring large numbers → RSA
• Discrete logarithm → ECC and Diffie-Hellman

Quantum computing represents a new technological era capable of solving problems that are practically impossible for traditional computers today. Based on quantum physics principles such as superposition and entanglement, this technology promises to transform fields like artificial intelligence, medicine, cybersecurity, finance and scientific simulation.

Rather than a replacement for classical computing, quantum computing will be a specialized tool to tackle problems of enormous complexity and accelerate the technological development of the future.

Phishing is a very common cyberattack technique that uses emails, messages or calls to deceive people. It relies on social engineering, where attackers impersonate trusted organizations to manipulate their victims. The goal is to make the user slip up: visiting fraudulent websites, downloading infected files or handing over sensitive data such as banking credentials.

It is the name given to the moment when a sufficiently advanced quantum computer can break the encryption systems used today across the internet, banks, governments and digital communications.

Today many systems use algorithms such as:

• RSA
• ECC (Elliptic Curve Cryptography)
• Diffie-Hellman

These work because traditional computers would take thousands of years to solve certain mathematical problems. A quantum computer, however, could solve them far faster using algorithms such as Shor's.

Ransomware is a type of malicious software that works like a digital kidnapping: once it infects a device, it encrypts the files or blocks access to the system so they cannot be used. The attackers then demand a ransom payment (usually in cryptocurrency) in exchange for the unlock key, threatening to erase the information permanently or leak it online. Despite the pressure, experts recommend not paying, since it does not guarantee data recovery and only encourages criminals to keep attacking.
