Table 1. AES and User Key Parameters
Parameter Name Description
XSK_BBRAM_PGM_OBFUSCATED_KEY_SLR_CONFIG_ORDER_0 Default = FALSE. By default, XSK_BBRAM_PGM_OBFUSCATED_KEY_SLR_CONFIG_ORDER_0 is FALSE. BBRAM is programmed with a non-obfuscated key provided in XSK_BBRAM_AES_KEY_SLR_CONFIG_ORDER_0 and DPA protection can be either in enabled/disabled state. TRUE programs the BBRAM with key provided in XSK_BBRAM_OBFUSCATED_KEY_SLR_CONFIG_ ORDER_0 and DPA protection cannot be enabled.
XSK_BBRAM_PGM_OBFUSCATED_KEY_SLR_CONFIG_ORDER_1 Default = FALSE. By default, XSK_BBRAM_PGM_OBFUSCATED_KEY_SLR_CONFIG_ORDER_1 is FALSE. BBRAM is programmed with a non-obfuscated key provided in XSK_BBRAM_AES_KEY_SLR_CONFIG_ORDER_1 and DPA protection can be either in enabled/disabled state. TRUE programs the BBRAM with key provided in XSK_BBRAM_OBFUSCATED_KEY_SLR_CONFIG_ ORDER_1 and DPA protection cannot be enabled.
XSK_BBRAM_PGM_OBFUSCATED_KEY_SLR_CONFIG_ORDER_2 Default = FALSE. By default, XSK_BBRAM_PGM_OBFUSCATED_KEY_SLR_CONFIG_ORDER_2 is FALSE. BBRAM is programmed with a non-obfuscated key provided in XSK_BBRAM_AES_KEY_SLR_CONFIG_ORDER_2 and DPA protection can be either in enabled/disabled state. TRUE programs the BBRAM with key provided in XSK_BBRAM_OBFUSCATED_KEY_SLR_CONFIG_ ORDER_2 and DPA protection cannot be enabled.
XSK_BBRAM_PGM_OBFUSCATED_KEY_SLR_CONFIG_ORDER_3 Default = FALSE. By default, XSK_BBRAM_PGM_OBFUSCATED_KEY_SLR_CONFIG_ORDER_3 is FALSE. BBRAM is programmed with a non-obfuscated key provided in XSK_BBRAM_AES_KEY_SLR_CONFIG_ORDER_3 and DPA protection can be either in enabled/disabled state. TRUE programs the BBRAM with key provided in XSK_BBRAM_OBFUSCATED_KEY_SLR_CONFIG_ ORDER_3 and DPA protection cannot be enabled.
XSK_BBRAM_OBFUSCATED_KEY_SLR_CONFIG_ORDER_0 Default = b1c276899d71fb4cdd4a0a7905ea46c2e11f9574d09c7ea23b70b67de713ccd1. The value is converted to hex buffer and the key is programmed into BBRAM, when program API is called. It must be 64 characters long, valid characters are 0-9,a-f,A-F. Any other character is considered as invalid string and does not program BBRAM.
Note: For writing the OBFUSCATED Key, XSK_BBRAM_PGM_OBFUSCATED_KEY_SLR_CONFIG_ORDER_0 should have TRUE value.
XSK_BBRAM_OBFUSCATED_KEY_SLR_CONFIG_ORDER_1 For writing the OBFUSCATED Key, XSK_BBRAM_PGM_OBFUSCATED_KEY_SLR_CONFIG_ORDER_1 should have TRUE value.
XSK_BBRAM_OBFUSCATED_KEY_SLR_CONFIG_ORDER_2 Default = b1c276899d71fb4cdd4a0a7905ea46c2e11f9574d09c7ea23b70b67de713ccd1. The value is converted to hex buffer and the key is programmed into BBRAM, when program API is called. It must be 64 characters long, valid characters are 0-9,a-f,A-F. Any other character is considered as invalid string and does not program BBRAM.
Note: For writing the OBFUSCATED Key, XSK_BBRAM_PGM_OBFUSCATED_KEY_SLR_CONFIG_ORDER_2 should have TRUE value.
XSK_BBRAM_OBFUSCATED_KEY_SLR_CONFIG_ORDER_3 Default = b1c276899d71fb4cdd4a0a7905ea46c2e11f9574d09c7ea23b70b67de713ccd1.
