Method and system for generating secret key using non-communicating entity

A method for performing a key recovery procedure is disclosed. The method includes inputting, in a user device, a user identifier unique to a user. The user device may then obfuscate the user identifier to form an obfuscated user identifier. The user device may then transmit the obfuscated user identifier to the first entity computer and the second entity computer. The method may then include the first entity computer generating a first output using the obfuscated user identifier and the first share, and the second entity computer generating a second output using the obfuscated user identifier and the second share. In response to transmitting the obfuscated identifier, the user device may receive a first output from the first physical computer and a second output from the second physical computer. The user device may then generate a secret key after processing the first output and the second output, thereby completing the key recovery process. 公开了一种用于执行密钥恢复过程的方法。所述方法包括在用户装置中输入对用户唯一的用户标识符。然后，用户装置可以将用户标识符模糊化以形成
