PKI operation
In a PKI-enabled network, an entity can request a local certificate from the CA and the device can check
the validity of certificates. Here is how it works:
1. An entity submits a certificate request to the RA.
2. The RA reviews the identity of the entity and then sends the identity information and the public key
with a digital signature to the CA.
3. The CA verifies the digital signature, approves the application, and issues a certificate.
4. The RA receives the certificate from the CA, sends it to the LDAP server or other distribution points
to provide directory navigation service, and notifies the entity that the certificate is successfully
issued.
5. The entity obtains the certificate. With the certificate, the entity can communicate with other entities
safely through encryption and digital signature.
6. The entity makes a request to the CA when it needs to revoke its certificate. The CA approves the
request, updates the CRLs and publishes the CRLs on the LDAP server or other distribution points.
PKI applications
The PKI technology can satisfy the security requirements of online transactions. As an infrastructure, PKI
has a wide range of applications. The following lists some common application examples:
• VPN—A VPN is a private data communication network built on the public communication
infrastructure. A VPN can leverage network layer security protocols (for instance, IPsec) in
conjunction with PKI-based encryption and digital signature technologies for confidentiality.
• Secure email—Emails require confidentiality, integrity, authentication, and non-repudiation. PKI
can address these needs. The secure email protocol that is developing rapidly is S/MIME, which is
based on PKI and allows for transfer of encrypted mails with signature.
• Web security—For Web security, two peers can establish an SSL connection first for transparent
and secure communications at the application layer. With PKI, SSL enables encrypted
communications between a browser and a server. Both of the communication parties can verify
each other's identity through digital certificates.
FIPS compliance
The device supports the FIPS mode that complies with NIST FIPS 140-2 requirements. Support for features,
commands, and parameters might differ in FIPS mode (see "Configuring FIPS") and non-FIPS mode.
