Encryption Application Using Verifiable Secret Sharing Scheme

Abstract

Secret sharing scheme is used to produce a secret key obtained from a calculation against a certain number of keys in a group. The problem occurs when one or more keys in the group are fake or intentionally faked. A verifiable secret sharing system is proposed in this paper so that it detects any fake keys in a group before being used for resulting the right secret key. Initial system definitions are the basis for writing codes in its system development. Units and integration test is implemented when all units of the system is ready. Repetition is applied to its development stages until the test results show that all system functionalities are working as expected and the system has succeeded in detecting fake keys in the group.
