What is Quantum Entropy?

Entropy is a measure of randomness in a system, and quantum entropy is randomness based on quantum sources. Qrypt uses sensitive measurement electronics on different types of quantum sources to produce true random numbers.

What are the limitations of end-to-end encryption in current chat messaging?

End-to-end encryption, while secure against current threats, is not quantum- secure and thus vulnerable to future quantum computing attacks. Quantum security is essential now because data is already being harvested and stored by adversaries for future decryption once quantum computers become capable of breaking current encryption algorithms.

Where does data harvesting occur?

Q: Where does data harvesting occur?

Encrypted data can be intercepted and harvested at various points, including the user's server, through BGP hijacking, tapping undersea cables, and satellite data interception, posing risks of future decryption and exploitation of the data by adversaries using quantum computing capabilities.

Encrypted data, while in transmission, is susceptible to interception and harvesting at multiple points, each posing distinct risks and challenges. At the user’s server, data can be intercepted due to weak cryptography or mishandling of certificates. BGP hijacking involves deceiving servers about a compromised system’s data delivery capability, rerouting data through unexpected paths. Undersea cables, especially in international waters, can be tapped by entities like governments or non-state actors, intercepting data transmitted through them. Satellite data can be intercepted using relatively inexpensive equipment, making it a vulnerable point for data transmission, especially in remote or international locations. Each interception point poses risks of the harvested data being stored and decrypted in the future using advanced quantum computing capabilities, making the implementation of quantum-secure cryptography imperative to safeguard against future data exploitation.
