What Is a Certification Path?
This section describes what is a certificate path or certificate chain - An ordered list of certificates where the subject entity of one certificate is identical to the issuing entity of the next certificate.
Certification Path: Also called Certificate Chain. An ordered list of certificates where the subject entity of one certificate is identical to the issuing entity of the next certificate.
A certification path can also be defined as an ordered list of certificates where the issuing entity of one certificate can be identified as the subject entity of the previous certificate. But the first certificate has to be a special one, because there is no previous certificate to identify the issuing entity. The first certificate must be a self-signed certificate, where the issuing entity is the same as the subject entity.
For example, the following diagram shows you a certification path:
Certificate 1 Issuer: Herong Yang Subject: Herong Yang Certificate 2 Issuer: Herong Yang Subject: John Smith Certificate 3 Issuer: John Smith Subject: Bill White Certificate 4 Issuer: Bill White Subject: Tom Bush
