Digital Certificate The digital equivalent of an ID card used in conjunction with a public key
encryption system. Digital certificates are issued by a trusted third party
known as a “Certificate Authority” (CA) such as VeriSign
(
www.verisign.com). The CA verifies that a public key belongs to a
specific company or individual (the “Subject”), and the validation process
the public key goes through to determine if the claim of the subject is
correct and depends on the level of certification and the CA.
Digital Signature
A digital signature is an encrypted digest of the file being signed. The file
can be a message, a document, or a driver program. The digest is
computed from the contents of the file by a one-way hash function such
as MD5 or SHA-1 and then encrypted with the private part of a public or
private key pair. To prove that the file was not tampered with, the recipient
uses the public key to decrypt the signature back into the original digest,
recomputes a new digest from the transmitted file and compares the two
to see if they match. If they do, the file has not been altered in transit by
an attacker.
DNS
Domain Name System, an IETF standard for ASCII strings to represent IP
addresses. The Domain Name System (DNS) is a distributed Internet
directory service. DNS is used mostly to translate between domain names
and IP addresses.
