Internal Credential Management is the Government of Canada PKI service provider.

For some time now, the Government of Canada has been applying information technologies to its processes to achieve more cost-effective, accessible, responsive and citizen-centered government services. A key initiative has been the establishment of the Government of Canada Public Key Infrastructure to meet the security requirements of federal electronic services delivery, promote the information technology industry and guarantee Canada's role as a key global player in the growing electronic service delivery and electronic commerce fields.

The government's commitment to electronic services delivery was highlighted when it mandated the Internal Credential Management division of PWGSC to establish and operate a Public Key Infrastructure ( PKI) for the GC.

This Government of Canada PKI provides departments an efficient, effective, common basis for the secure electronic delivery of federal services and programs. The ultimate goal of the government's PKI strategy is the establishment of a secure federal electronic service delivery system based largely on a centrally managed Public Key Infrastructure cross-certified with other PKIs.

ICM operates and maintains the Certification Authority, which is a trusted third party responsible for issuing digital certificates. A federal department may operate its own Certification Authority, or choose to enter into a contract with another organization for the provision of Certification Authority services, however, an exception must be granted by TB before doing so.

Departmental Local Registration Authorities(LRAs) or the Online Registration and Credential Administration (ORCA) system ensure that the individuals or organizations applying for granted digital certificates or MyKey are, in fact, whom they claim to be. Having verified the applicant's identity, they instruct Internal Credential Management to issue the certificate.

Online Registration and Certificate Administration

Online Registration and Credential Administration (ORCA) is an online system that enables users to securely create and manage their PKI identity-based credential (MyKey).  MyKey is acquires through ORCA using information, such as name, e-mail, address, personal identification number (PRI) and data of birth. ORCA also enables users to recover their MyKey, if misplaced or the password is forgotten, as well as change information including name, password or organization.

MyKey

Along with building ORCA, ICM is also branding the current ID-Based Certificate to MyKey.  MyKey, also referred to as : PKI Key, PKI Certificate, Entrust Profile or ID-Based Certificate provides the same functionality as the current PKI Key, we just wanted to standardize the name.
So when you talk about a PKI Key or a Digital Certificate or a Common Credential, you’re talking about MyKey.
