Therefore, each CA (root or intermediate) is only responsible for tracking the revocation of certificates it alone has issued. Consider the scenario where a root CA issues certificates to three intermediate CAs: A, B, and C: The root CA has issued a total of three certificates. The newly created intermediate CAs then issue their own certificates:
The roles of root certificate, intermediate certificate and end-entity certificate as in the chain of trust. In computer security, a chain of trust is established by validating each component of hardware and software from the end entity up to the root certificate. It is intended to ensure that only trusted software and hardware can be used ...
A root certificate is the top-most certificate of the tree, the private key which is used to "sign" other certificates. All certificates signed by the root certificate, with the "CA" field set to true, inherit the trustworthiness of the root certificate—a signature by a root certificate is somewhat analogous to "notarizing" identity in the ...
The TPM manufacturer usually provisions endorsement key certificates in TPM non-volatile memory. The certificates assert that the TPM is authentic. Starting with TPM 2.0, the certificates are in X.509 DER format. These manufacturers typically provide their certificate authority root (and sometimes intermediate) certificates on their web sites.
The end-user of an operating system or web browser is implicitly trusting in the correct operation of that software, and the software manufacturer in turn is delegating trust for certain cryptographic operations to the certificate authorities responsible for the root certificates.

A loadable kernel module (LKM) is an executable library that extends the capabilities of a running kernel, or so-called base kernel, of an operating system.LKMs are typically used to add support for new hardware (as device drivers) and/or filesystems, or for adding system calls.
chroot is an operation on Unix and Unix-like operating systems that changes the apparent root directory for the current running process and its children.A program that is run in such a modified environment cannot name (and therefore normally cannot access) files outside the designated directory tree.
