Method for providing user data encryption key protection in simple authentication environment and system thereof

A system for protecting a user data encryption key in a simple authentication environment, the system comprising:

• one or more processors;
• and
• a memory configured to store instructions,
• wherein the one or more processors are configured to perform, by executing the stored instructions:
• encrypting a private key, which is generated through a key management server, based on a password acquired from login information of a user terminal;
• receiving an authentication key, which is generated through the key management server, in response to a simple authentication registration request of the user terminal;
• decrypting the encrypted private key based on the password acquired from the login information;
• encrypting the decrypted private key based on the authentication key;
• and
• transmitting the encrypted private key to the user terminal.

A non-transitory a computer-readable recording medium storing a computer program, wherein the computer program is executable by at least one processor to perform:

• encrypting a private key, which is generated through a key management server, based on a password acquired from login information of a user terminal;
• receiving, an authentication key, which is generated through the key management server, in response to a simple authentication registration request of the user terminal;
• decrypting the encrypted private key based on the password acquired from the login information;
• encrypting the decrypted private key based on the authentication key;
• and
• transmitting the encrypted private key to the user terminal.
