Efficient digital e-sign software,
A PKI (public key infrastructure) enables users of a basically un-secure
public network such as the Internet to securely and privately
exchange
data and money through the use of a public and a
private cryptographic
key pair that is obtained and shared through a trusted authority. The
public key infrastructure provides for a digital certificate that can
identify an individual or an organization and directory services that
can store and, when necessary, revoke the certificates. Although the
components of a PKI are generally understood, a number of different
vendor approaches and services are emerging. Meanwhile Efficient
digital e-sign software, an Internet
standard for PKI is being worked on.

The public key infrastructure assumes
the use of
Efficient digital e-sign software, which is the most common
method on the Internet for authenticating a message sender or encrypting
a message.
Traditional cryptography has usually involved the creation
and sharing of a secret key for the encryption and decryption of
messages. This secret or private key system has the significant flaw
that if the key is discovered or intercepted by someone else, messages
can easily be decrypted. For this reason, public key cryptography and
the public key infrastructure is the preferred approach on the Internet.
(The private key system is sometimes known as
Efficient digital e-sign software and
the public key system as asymmetric cryptography.)
A public key infrastructure consists
of:
- A certificate authority (CA) that
issues and verifies digital certificate. A certificate includes the
public key or information about the public key
- A registration authority (RA) that
acts as the verifier for the certificate authority before a digital
certificate is issued to a requestor
- One or more directories where the
certificates (with their public keys) are held
- An
