📌 Post-Quantum Cryptography Summary

Post-Quantum Cryptography refers to cryptographic methods designed to remain secure against the powerful computers of the future called quantum computers. Current encryption techniques such as RSA and ECC could be broken by quantum computers, making sensitive data vulnerable. Post-Quantum Cryptography develops new algorithms that even quantum computers would find extremely difficult to crack, ensuring long-term protection for communication and data.

🙋🏻‍♂️ Explain Post-Quantum Cryptography Simply

Imagine you have a safe with a lock that is very hard to pick using normal tools. But someone invents a new kind of tool that can open your safe easily. Post-Quantum Cryptography is like inventing a brand new type of lock that cannot be opened, even with the new tool, keeping your valuables secure.

📅 How Can it be used?

Upgrade secure messaging apps to use post-quantum cryptography algorithms to protect conversations against future quantum threats.

🗺️ Real World Examples

A government agency updates its secure communication network to use post-quantum cryptography, ensuring that classified information remains confidential even if intercepted and stored by adversaries with future quantum computers.

A bank implements post-quantum cryptographic algorithms in its online banking system to protect customer transactions and account details from potential quantum-enabled cyber attacks in the future.

✅ FAQ

Quantum computers have the potential to break the encryption methods we use today, such as RSA and ECC. This means information we think is safe could become easy to access. Post-Quantum Cryptography aims to create new ways of keeping data private, even if someone has a powerful quantum computer.

No one knows the exact timeline, but researchers are already preparing because it is possible that strong quantum computers could be developed in the next few decades. By updating our security now, we can protect sensitive data before quantum computers become a real threat.

Most people will not notice any difference in their daily lives, but the security behind things like online banking, emails, and personal chats will be much stronger. Post-Quantum Cryptography works in the background to keep your information safe for years to come.

Behaviour Flags

Behaviour flags are markers or indicators used in software and systems to track or signal specific actions, choices, or patterns of behaviour. They help identify when certain events occur, such as a user clicking a button, exceeding a usage limit, or breaking a rule. These flags can then trigger automated responses or inform further actions, making systems more responsive and adaptive.

Predictive Analytics Integration

Predictive analytics integration involves combining predictive models and analytics tools with existing software systems or business processes. This allows organisations to use historical data and statistical techniques to forecast future events or trends. By embedding these insights into daily workflows, businesses can make more informed decisions and respond proactively to changing conditions.

E-Invoicing Process

The e-invoicing process is the digital creation, sending, and receipt of invoices between businesses or organisations. Instead of using paper or PDF files, invoices are generated in a standard electronic format, making them easier to process and track. This method often integrates directly with accounting or enterprise systems, reducing errors and speeding up payment cycles.

Blockchain Supply Chain Tracking

Blockchain supply chain tracking is a method of recording and sharing information about products as they move through the supply chain using blockchain technology. This approach creates a secure and unchangeable digital record of every step, from production to delivery. It helps businesses and consumers verify the origin, authenticity, and journey of goods, improving trust and transparency.

Neural Network Quantisation Techniques

Neural network quantisation techniques are methods used to reduce the size and complexity of neural networks by representing their weights and activations with fewer bits. This makes the models use less memory and run faster on hardware with limited resources. Quantisation is especially valuable for deploying models on mobile devices, embedded systems, or any place where computational power and storage are limited.
