Separate cryptographic keys for multiple modes

A method comprising:

• receiving, by a security apparatus, a request from an application associated with a security level to access a cryptographic key stored in the security apparatus;
• identifying, by the securing apparatus, the security level to which the application is associated;
• selecting, by the security apparatus, one of a plurality of cryptographic keys based on the identified security level, each cryptographic key of the plurality of keys providing access to a different security mode of operation of the security apparatus;
• implementing the selected cryptographic key to validate an integrity of a code image of the application that the security apparatus is to load;
• and
• one of:
• based on the integrity of the code image being validated, allowing the application access to the security mode of operation corresponding to the identified security level;
• or
• based on the integrity of the code image not being validated, denying the application access to the security mode of operation corresponding to the identified security level.

A non-transitory computer readable medium on which is stored machine readable instructions that when executed by a processor, cause the processor to:

• receive a request from an application to access a security mode of a plurality of security modes of a security apparatus, each of the plurality of security modes having a corresponding cryptographic key;
• identify a personality to which the application is directed;
• identify a security mode of the security apparatus corresponding to the identified personality;
• implement the cryptographic key corresponding to the identified security mode to validate an integrity of the application;
• and
• based on the integrity of the application being validated, allow the application to access the identified security mode of the security apparatus.
