Lake City Bank utilizes several layers of technology to ensure the confidentiality of your transactions across the Internet. Security begins with your browser. SSL protocol (Secure Sockets Layer) is used to provide privacy for the data flowing between the browser and the bank server.
SSL is an open protocol for securing data communication across computer networks, and it provides a secure channel for data transmission through its encryption capabilities. It allows for the transfer of digitally signed certificates for authentication procedures and provides message integrity, ensuring that the data can't be altered en-route.
To start a transaction, the customer uses his or her browser to send a secure message via SSL to the bank. The bank responds by sending a certificate which contains the bank's public key. The browser authenticates the certificate, then generates a session key which is used to encrypt data traveling between the customer's browser and the bank server.
The session key is encrypted using the bank's public key and sent back to the bank. The bank decrypts this message using its private key, then uses the session for the remainder of the communication.
By exchanging messages using the public/private key pair, the customer can be assured that they are actually communicating with the bank, and not a third party trying to intercept the transaction. When a session is encrypted, the key icon at the lower left corner of the browser's screen becomes solid, and a blue line appears at the top of the screen. If the key icon appears broken, encryption is not in use and the current session is not secure.
