In the wave of digitization, encryption technology has become a core tool for protecting privacy and security. Recently, a roundtable discussion on encryption technology brought together industry experts to explore end-to-end encryption, blockchain security, and the challenges posed by quantum computing. Participants emphasized that encryption is not just a technical issue, but also concerns human rights and freedom. Although there is tension between government regulation and privacy protection, the consensus is: strengthening encryption standards and promoting open-source collaboration are essential to building a safer digital future. This discussion provided valuable ideas for balancing innovation and security, and also called on the public to value data autonomy.
