Abstract
The subject matter discloses a computerized system for securing data, comprising a first node, comprising a first memory storage configured to store a first share of a cryptographic key and a communication module, a second node, in communication with the first node, comprising a second memory storage configured to store a second share of the cryptographic key, wherein the first share and the second share of the cryptographic key are required to perform a cryptographic operation using a multi-party computation (MPC) process, wherein the second node further comprises a control unit configured to change an operation mode of the second share from enable to disable, wherein the disable operation mode prevents performing the cryptographic operation using the MPC process.
