7 This option enables the integrity subsystem, which is comprised
8 of a number of different components including the Integrity
9 Measurement Architecture (IMA), Extended Verification Module
10 (EVM), IMA-appraisal extension, digital signature verification
11 extension and audit measurement log support.

24 This option enables digital signature verification support
25 using multiple keyrings. It defines separate keyrings for each
26 of the different use cases - evm, ima, and modules.
27 Different keyrings improves search performance, but also allow
28 to "lock" certain keyring to prevent adding new keys.
29 This is useful for evm and module keyrings, when keys are
30 usually only added from initramfs.

49 In addition to enabling integrity auditing support, this
50 option adds a kernel parameter 'integrity_audit', which
51 controls the level of integrity auditing messages.
52 0 - basic integrity auditing messages (default)
53 1 - additional integrity auditing messages
54
55 Additional informational integrity auditing messages would
56 be enabled by specifying 'integrity_audit=1' on the kernel
57 command line.
