Abstract
Secure extraction of state information of a computer system is provided. A method includes obtaining, by a security engine of a system, a public encryption key associated with a private decryption key; generating an extraction key that is inaccessible outside of the security engine; encrypting the extraction key with the public encryption key, to thereby obtain an encrypted extraction key; collecting state information of the system; encrypting the collected state information with the extraction key and storing the encrypted collected state information; and based on a request for access to the stored encrypted collected state information by a request for the extraction key, providing the extraction key to facilitate decryption of the stored encrypted state information.
