Efficient esignature,
Each signatory has their
own paired public.
|
Efficient esignature
DSA is a pair of large numbers that are
computed according to the specified algorithm within parameters that
enable the authentication
of the signatory, and as a consequence, the integrity of the data
attached. Digital signatures are generated through DSA, as well as
verified. Signatures are generated in conjunction with the use of a
private key; verification takes place in reference to a corresponding
public key. Each signatory has their own paired public (assumed to be
known to the general public) and private (known only to the user) keys.
Because a signature can only be generated by an authorized person using
their private key, the corresponding public key can be used by anyone to
verify the Efficient esignature.
In
Efficient esignature, a public and private key are created
simultaneously using the same algorithm (a popular one is known as RSA)
by a certificate authority (CA). The private key is given only to the
requesting party and the public key is made publicly available (as part
of a digital certificate) in a directory that all parties can access.
The private key is never shared with anyone or sent across the Internet.
You use the private key to decrypt text that has been encrypted with
your public key by someone else (who can find out what your public key
is from a public directory),
Efficient esignature. Thus, if I send you a message, I can find
out your public key (but not your private key) from a central
administrator and encrypt a message to you using your public key. When
you receive it, you decrypt it with your private key. In addition to
encrypting messages (which ensures privacy), you can authenticate
yourself to me (so I know that it is really you who sent the message) by
using your
Efficient esignature
to encrypt a digital certificate.
