HE-TEST-WORKER

• Homomorphic Encryption Test Worker
  • Performs computations on encrypted data without decrypting it through REST API and blockchain network

How to run

Build docker image

docker build -t he-test-worker .

Run image as a container

docker run -dp [EXPOSED_PORT]:3000 he-test-worker

Homomorphic Encryption

• Use ain-js

Encrypt data

import Ain from '@ainblockchain/ain-js';

const ain = new Ain('http://node.ainetwork.ai:8080');
await ain.he.init();
const TEST_DATA = Float64Array.from({ length: ain.he.seal.encoder.slotCount }).map((x, i) => i);
const cipherText = ain.he.encrypt(TEST_DATA);
const encrypted = cipherText.save(); // base64 string

Decrypt result

import Ain from '@ainblockchain/ain-js';

const ain = new Ain('http://node.ainetwork.ai:8080');
await ain.he.init();
const result = ... // get result from he-test-worker
const decrypted = ain.he.decrypt(result); // decrypted as Float64Array format

APIs

[POST] /he/double

• Body parameters
  • operand: encrypted base64 string
• Response
  • result: encrypted base64 string
    • encrypted result of operand * 2

[POST] /he/add

• Body parameters
  • operand1: encrypted base64 string
  • operand2: encrypted base64 string
• Response
  • result: encrypted base64 string
    • encrypted result of operand1 + operand2

[POST] /he/request

• Endpoint for blockchain based HE calculation
  • DO NOT CALL THIS ENDPOINT DIRECTLY
• Body parameters
  • function: blockchain function setting parameters
  • transaction: transaction info which caused this API call
    • tx_body
