In cryptography and computer security, a root certificate is a public key certificate that identifies a root certificate authority (CA). [1] Root certificates are self-signed (and it is possible for a certificate to have multiple trust paths, say if the certificate was issued by a root that was cross-signed) and form the basis of an X.509-based ...
Currently the majority of web browsers are shipped with pre-installed intermediate certificates issued and signed by a certificate authority, by public keys certified by so-called root certificates. This means browsers need to carry a large number of different certificate providers, increasing the risk of a key compromise. [43]

For example, attackers might compromise a certificate authority, and then mis-issue certificates for a web origin. To combat this risk, the HTTPS web server serves ...
