Abstract
A system, method, and computer program product are provided for sensitive data recovery in high security systems. In operation, a client device receives a request by a user to initiate a data recovery process to recover data that is encrypted. The client device generates a new data recovery request key pair. The client device creates a data recovery request that includes a data recovery request public key. The client device signs the data recovery request using an identity private key that is associated with a certificate issued by a certification authority (CA). The client device sends the data recovery request to a server system storing the data. The server system accesses an offline data recovery subsystem (ODRS) storing a data recovery key pair to authenticate the user. The ODRS generates and stores a secret data recovery code. The client device receives the secret data recovery code that was communicated to the user. The client device sends the secret data recovery code along with the data recovery request to the server system. The server system verifies the received secret data recovery code against the stored secret data recovery code. The server system verifies a public key associated with the received data recovery request against a public key associated with a stored recovery request. The server system identifies the data recovery request as authenticated. The ODRS verifies a request signature associated with the data recovery request. The ODRS verifies the encrypted signature against encrypted and signed recovery data. The ODRS verifies that a user ID in a password reset request matches a user ID in a message encryption key signature. The ODRS decrypts the data recovery key pair and re-encrypts the data recovery key pair to the data recovery request public key. The ODRS stores the re-encrypted data recovery key pair associated with the data recovery request. The client device queries the server system to obtain the data. The server system returns the data to the client device. The client device decrypts the data using a data recovery private key.
