19. Security Secure Sockets Layer
Secure Sockets Layer, a protocol developed by Netscape for transmitting private documents via the Internet.
Process works in the following steps:
The client makes a connection to the secure port (an “https” connection instead of an “http” connection). Along wit the request, it sends its SSL version and some other data.
When the server receives this information, it sends back its own SSL version and its certificate. It may also request the client’s certificate if client authentication is required.
the client receives the certificate and checks its validity. It checks whether or not the certificate has expired and whether it was issued by a trusted CA. Clients maintain a list of trusted CA certificates to determine whether the received certificate should be trusted.
The client now creates a “premaster secret” to be used in this session. This secret is encrypted using the Public Key retrieved from the server’s certificate and then sent to the server.
The server uses its Private Key to decrypt the premaster secret and then creates a master secret. The client also creates a master secret using the premaster secret.
The master secret is used by both to created keys for encrypting and decrypting information, as well as to detect any changes made by somebody during data transmission.
The client informs the server that it has been read and that it will encrypt messages using the Session Key. The server also sends a similar message to the client.

The acquiring bank requests the brand to clear for the credit amount and gets paid. Then brand asks for clearance to the issuer bank.
The amount is transferred from issuer to brand. The same amount is deducted from the cardholder’s account in the issuing band.
