Archived TD0023: Update to FCS_CKM_EXT.4 in MDF PP v1.1
PP_MD_V1.1, requirement FCS_CKM_EXT.4; PP_MD_V2.0, requirement FCS_CKM_EXT.4
The FCS_CKM_EXT.4 requirement in MDF PP v1.1 is currently inaccurate with respect to memory technologies. The requirement addresses "volatile EEPROM" and "volatile flash" memories; EEPROM and flash are non-volatile memory technologies. Volatile memory technologies in use in mobile devices can be effectively cleared using different methods than those allowed for EEPROM and flash.
The FCS_CKM_EXT.4 requirement in MDF PP v1.1 can be replaced by the same requirement from MDF PP v2.0.
The FCS_CKM_EXT.4 requirement in MDF PP v2.0 accurately captures the options needed for mobile devices while not significantly increasing the amount of work that needs to be performed in both meeting the requirement and performing the assurance activities.
