certain mathematical conditions, and then use the integers to each
separately compute a public-private key pair. They send each other
their public key. Each person uses their own private key and the
other person's public key to compute a key, k, that, because of
the mathematics of the algorithm, is the same for each of them.
Passive wiretapping cannot learn the shared k, because k is not
transmitted, and neither are the private keys needed to compute k.
However, without additional mechanisms to authenticate each party
to the other, a protocol based on the algorithm may be vulnerable
to a man-in-the-middle attack.
$ digest
See: message digest.
$ digital certificate
(I) A certificate document in the form of a digital data object (a
data object used by a computer) to which is appended a computed
digital signature value that depends on the data object. (See:
attribute certificate, capability, public-key certificate.)
(D) ISDs SHOULD NOT use this term to refer to a signed CRL or CKL.
Although the recommended definition can be interpreted to include
those items, the security community does not use the term with
those meanings.
$ digital certification
(D) ISDs SHOULD NOT use this term as a synonym for
"certification", unless the context is not sufficient to
distinguish between digital certification and another kind of
certification, in which case it would be better to use "public-key
certification" or another phrase that indicates what is being
certified.
$ digital document
(I) An electronic data object that represents information
originally written in a non-electronic, non-magnetic medium
(usually ink on paper) or is an analogue of a document of that
type.
$ digital envelope
(I) A digital envelope for a recipient is a combination of (a)
encrypted content data (of any kind) and (b) the content
encryption key in an encrypted form that has been prepared for the
use of the recipient.
(C) In ISDs, this term should be defined at the point of first use
because, although the term is defined in PKCS #7 and used in
S/MIME, it is not yet widely established.
