Abstract

See full text

Techniques are provided for firmware protection using multi-chip storage of firmware images. One method comprises obtaining a firmware image; encrypting the firmware image; splitting the encrypted firmware image into a plurality of encrypted firmware image portions; and storing the plurality of encrypted firmware image portions on a plurality of recovery chips, wherein a threshold number of the encrypted firmware image portions from at least two different recovery chips are needed to reconstruct the firmware image. The threshold number of the encrypted firmware image portions can be obtained from the at least two different recovery chips and a validation can be applied to the obtained encrypted firmware image portions. The threshold number of encrypted firmware image portions may be obtained in response to a chip that stores the firmware image being inactive.
