#config INTEGRITY	bool "Integrity subsystem"	depends on SECURITY	default y	help	  This option enables the integrity subsystem, which is comprised	  of a number of different components including the Integrity	  Measurement Architecture (IMA), Extended Verification Module	  (EVM), IMA-appraisal extension, digital signature verification	  extension and audit measurement log support. 	  Each of these components can be enabled/disabled separately.	  Refer to the individual components for additional details. if INTEGRITY config INTEGRITY_SIGNATURE	bool "Digital signature verification using multiple keyrings"	depends on KEYS	default n	select SIGNATURE	help	  This option enables digital signature verification support	  using multiple keyrings. It defines separate keyrings for each	  of the different use cases - evm, ima, and modules.	  Different keyrings improves search performance, but also allow	  to "lock" certain keyring to prevent adding new keys.	  This is useful for evm and module keyrings, when keys are	  usually only added from initramfs. config INTEGRITY_ASYMMETRIC_KEYS	bool "Enable asymmetric keys support"	depends on INTEGRITY_SIGNATURE	default n        select ASYMMETRIC_KEY_TYPE        select ASYMMETRIC_PUBLIC_KEY_SUBTYPE        select CRYPTO_RSA        select X509_CERTIFICATE_PARSER	help	  This option enables digital signature verification using	  asymmetric keys. config INTEGRITY_TRUSTED_KEYRING	bool "Require all keys on the integrity keyrings be signed"	depends on SYSTEM_TRUSTED_KEYRING	depends on INTEGRITY_ASYMMETRIC_KEYS	default y	help	   This option requires that all keys added to the .ima and	   .evm keyrings be signed by a key on the system trusted	   keyring. config INTEGRITY_AUDIT	bool "Enables integrity auditing support "	depends on AUDIT	default y	help	  In addition to enabling integrity auditing support, this	  option adds a kernel parameter 'integrity_audit', which	  controls the level of integrity auditing messages.	  0 - basic integrity auditing messages (default)	  1 - additional integrity auditing messages 	  Additional informational integrity auditing messages would	  be enabled by specifying 'integrity_audit=1' on the kernel	  command line. source security/integrity/ima/Kconfigsource security/integrity/evm/Kconfig endif   # if INTEGRITY
