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.
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.
