AB - Existing proxy re-encryption-based information sharing schemes suffer from a single point of failure, as the master private key is concentrated in a single entity. This paper proposes a distributed information sharing architecture that combines Distributed Key Generation (DKG) with Threshold Proxy Re-Encryption (TPRE). In the proposed architecture, blockchain nodes jointly generate the master public key, and the master private key never exists in complete form in any single memory. The data owner encrypts the original data once with a one-time symmetric key and encapsulates the key under the master public key. When a smart contract approves an access request, each node generates a partial re-encryption result by combining its private key share with the recipient's public key. The recipient combines a threshold number of partial results and recovers the symmetric key with its own private key. Finally, the proposed structure analyzes security requirements such as confidentiality, availability, and antitrust, and verifies whether they are satisfied.
