Step 1: Generate Key Pair.

Please generate a homomorphic encryption public-private key pair, and securely store the private key yourself.

Step 2: Send Public Key.

The user sends his public key to the server.

Step 3: Select Gene File.

The user party selects the genetic file for diagnosis.

Step 4: Encrypt the genetic data using a public key.

The user encrypts the genetic file using their own public key.

Step 5: Send Encrypted Genetic Data.

The user sends their encrypted genetic data to the service provider.

Step 6: Start encrypted computation, wait for analysis results.

The requesting party initiates the computation task, and the service provider performs diagnostic calculations using 'encrypted genetic data + bioinformatics algorithms'.

Step 7: Use the private key to decrypt the analysis results.

The user receives the computation results, uses their private key to decrypt, and obtains the plaintext diagnostic results.
