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.

Why is Qrypt's Quantum Key Generation (QKG) a pertinent solution now, and how does it complement NIST PQC in mitigating quantum threats?

Qrypt's QKG provides immediate mitigation against quantum threats by enabling independent generation and non-transmission of encryption keys, safeguarding against potential future decryption. It complements NIST PQC by providing an additional layer of security, especially against HNDL attacks, and ensuring data security during the transition to post- quantum cryptographic standards.

Q: 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.

End-to-end encryption in chat messaging services, such as WhatsApp and Signal, provides security against present-day threats by ensuring that messages can only be read by the intended recipient. However, these services are not quantum-secure and are vulnerable to future quantum computing attacks. Quantum computers, once they become sufficiently advanced, will be able to break the encryption algorithms used by these services, exposing all harvested chat history and messages. Given that data is already being harvested and stored by adversaries, adopting quantum-secure encryption now is imperative to safeguard data against future quantum threats and to protect businesses and individuals from data breaches, intellectual property theft, and other cybercrimes.
