| Research Abstract |
By employing secret sharing techniques in terms of error-correcting codes, it is shown that the property of leakage-resilience could be achieved. As well, it is beneficial to make use of Deterministic Encryption to prevent information leakage. Provably in a mathematics way, Deterministic Encryption derived from error-correcting codes, is resistant to partially information leakage, because it is built in a secret sharing way. Furthermore, it is also shown that the new approach has achieved higher efficiency with PIR-based database searching techniques.
