AI Technical Summary
In existing cloud storage and online service scenarios, the use of passwords as cryptographic keys suffers from low entropy, vulnerability to attacks, reliance on transport layer security which is susceptible to defects, and the lack of a unified encryption framework leads to increased system complexity and security risks. It is also difficult to balance user data confidentiality with server auxiliary functions.
The method employs an unintentional password authentication key encapsulation approach, using high-entropy keys to encrypt data and encapsulating it with an easy-to-remember password to ensure that the password is hidden from other participants, thereby protecting user privacy data.
In cloud storage and online service scenarios, using password-encrypted data keys mitigates vulnerabilities in existing systems, ensures the security and integrity of user privacy data, simplifies key management, and reduces system complexity.
