Digital certificates. We have previously considered topics such as user authentication, document integrity checks, and encryption. The introduction of solutions to each of these topics serves to improve the reliability of networked resources and increase our confidence in on-line transactions.
·The registrant’s name
·Additional personal information such as an e-mail address for a person or a URL for a web server
·A unique registration number
·The name of the certificate authority
·The public key of the registrant
·Dates that reflect certificate validity (start and expiration dates)
·A digital signature “seal” from the CA that verifies authenticity of the certificate
Digital signatures are used to satisfy the on-line requirements for the functions served by traditional physical signatures.
·Adoptions, divorce, or other matters of family law
·Cancellation or termination of utility services (water, heat, power)
·Actions against the primary residence of an individual (eviction, foreclosure, etc.)
