Certifying Authority (CA) x� Public key infrastructure is a system of policies, procedures, people, hardware, software and services that support the use of public key cryptography to obtain secure communication PKI aims to increase the number of e-services of Government and Private entities to … Hierarchy of CA This will include descript ions and explanation s of These items are government property and may only be used for official purposes. stream Class 1 − These certificates can be easily acquired by supplying an email address. The CAs, which are directly subordinate to the root CA (For example, CA1 and CA2) have CA John Wack contributed material on PKI architectures.
