Transfer of ownership of a computing device via a security processor

A method implemented by a computing device, comprising:

• during a boot session of the computing device:
• detecting an indication of a transfer of ownership of the computing device from a first user to a second user, the first user being associated with a first set of fuses that stores a first public key associated with the first user, the first public key being used to verify information of the first user;
• and
• in response to detecting the indication of the transfer of ownership of the computing device from the first user to the second user:
• programming a second set of fuses to store a second public key, the second public key being used to verify information of the second user and being different from the first public key, wherein programming the second set of fuses does not alter the first set of fuses;
• and
• blowing one or more fuses in the first set of fuses to invalidate the first public key.

A computer-readable storage medium having program instructions recorded thereon that, when executed by a processor of a computing device, perform a method comprising:

• during a boot session of the computing device:
• detecting an indication of a transfer of ownership of the computing device from a first to a second, the first being associated with a first set of fuses that stores a first public key associated with the first;
• and
• in response to detecting the indication of the transfer of ownership of the computing device from the first to the second:
• programming a second set of fuses to store a second public key associated with the second, the indication of the transfer of ownership comprises comprising the second public key, wherein programming the second set of fuses does not alter the first set of fuses;
• and
• blowing one or more fuses in the first set of fuses to invalidate the first public key.
