The system first establishes trust in device certificates used to encrypt configuration data bound for a device and then permits a subscriber to demonstrate possession and usage of their CAC to generate two new derived credentials and recover existing email encryption keys. Public key certificates provide digital signature and encryption capabilities, which can be used to implement the following security services: Identification and Authentication: PKI provides for identification and authentication through digital signature.
If the signature is valid, then the Relying Party the person or system relying on the presented certificate for authentication or other security services has assurance that the entity participating in the transaction is the Subscriber the identity asserted by the certificate.
Data Integrity: PKI provides for data integrity through digital signature of information. If the recipient of digitally signed information is able to verify the signature on the information using the public key of the certificate used to generate the signature, then the recipient knows that the content has not changed since it was signed. Confidentiality: PKI provides confidentiality through encryption.
If the public key in a certificate is used to encrypt information, only the associated private key, held and kept secret by the entity named in the certificate, can decrypt that information. Technical non-repudiation can be considered a form of attribution, namely that the digitally signed information can be attributed to the entity identified in the certificate used to generate the signature.
DoD PKI. This is to prevent a key from being guessed. The PKI framework and service provider for the generation, production, distribution, control, accounting, and destruction of PK certificates. PKI provides an encryption capability and can be a tool for complying with encryption requirements in DoD Instruction Protecting networks largely rests on who is allowed inside the network.
DISA is defending against this threat by providing secure credentials not only for the traditional, computer-based network environment, but also for the rapidly growing mobile environment. We check email on it, we do our homework, we do research, pay our bills, and there is a lot of PII tied into that platform.
Non-person entities are devices with PKI certificates. Purebred is the program DISA uses to provide credentialing for its mobile capabilities. Purebred enables signed and encrypted email and secure web browsing without continuous need for a smart card reader and user Common Access Card CAC.
