definitions are useful for understanding how SBL(Supplier Busniess Link) works :
 Authentication is the
verification of the identity of a user or host. When you communicate over a network,
authentication ensures that you are communicating with the intended party and not an
imposter.
Encryption is the encoding
of data such that only the intended recipient can read it. Encryption hides the data from
eavesdroppers and ensures that only the intended recipient can read it.
A public key is a key that
a server or client publishes for use by other servers or clients. Others can use this key
to encrypt the data they send to the key owner, but no one can use it to decrypt the same
data."keys" explains keys in more detail.
A private key is a key that
a server or client keeps confidential. Only this key can decrypt data that is encrypted
with its counterpart, the public key.
A key pair consists of a
matching public and private key.
A secure server is a server
that uses the Secure Sockets Layer (SSL) protocol to encrypt data for transfer over TCP/IP
networks, including the Internet. Secure servers provide security and privacy on the World
Wide Web.
A certificate is a file
that contains information about a browser, server, proxy, or other network entity. It
includes identifying information, the entity public key, and a signature made by a
Certification Authority.
A Certification Authority
(CA) is a trusted third party that uses its private key to create unique signatures for
certificates. It publishes its public key, which servers and clients can use to verify
signatures made by that CA. |
