Abstract
Even with proper access privilege, when a secured file is classified, at least security clearance (e.g. a clearance key) is needed to ensure those who have the right security clearance can ultimately access the contents in the classified secured file. According to one embodiment, referred to as a two-0pronged access scheme, a security clearance key is generated and assigned in accordance with a user's security access level. A security clearance key may range from most classified to non-classified. Depending on implementation, a security clearance key with a security level may be so configured that the key can be used to access secured files classified at or lower than the security level or multiple auxiliary keys are provided when a corresponding security clearance key is being requested. The auxiliary keys are those keys generated to facilitate access to secured files classified respectively less than the corresponding security or confidentiality level.
