Modify Alluxio Client:
Extend the Alluxio client API to include methods for secure data access using SGX. Example:
public class SecureAlluxioClient {
public byte[] secureRead(String path) {
// Initialize SGX enclave
SGXEnclave enclave = new SGXEnclave();
enclave.init();
// Read encrypted data from Alluxio
byte[] encryptedData = AlluxioClient.read(path);
// Decrypt data within the enclave
byte[] decryptedData = enclave.decrypt(encryptedData);
// Return decrypted data
return decryptedData;
}
}
Data Processing within SGX Enclave:
Implement data processing logic inside the SGX enclave. Ensure that all sensitive operations are performed within the enclave. Example:
// SGX Enclave function
void processData(uint8_t* inputData, size_t inputSize, uint8_t* outputData, size_t* outputSize) {
// Decrypt data
uint8_t* decryptedData = decrypt(inputData, inputSize);
// Perform secure computations
uint8_t* processedData = compute(decryptedData, inputSize);
// Encrypt the processed data
uint8_t* encryptedOutput = encrypt(processedData, outputSize);
// Copy the result to output buffer
memcpy(outputData, encryptedOutput, *outputSize);
}
Secure Communication:
Use secure channels for data transfer between Alluxio and the enclave. Implement mutual attestation to verify the integrity of both endpoints. Example Use Case: Data Encryption: Encrypt all data stored in Alluxio and decrypt it within the TEE before processing. Data Processing: Perform secure data analytics within the TEE, ensuring sensitive data never leaves the secure enclave unencrypted.
Is there a case of the combination of allixio and TEE?
