Wireless Transport Layer Security (WTLS): The security layer of the WAP which provides privacy, data integrity and authentication for WAP services. WTLS, designed specifically for the wireless environment, is needed for the client and server to be authenticated in order for wireless transactions to remain secure and also because the connection needs to be encrypted. For example, a user making a transaction with a bank over a wireless device needs to know that the connection is secure and private and not subject to a security breach during transfer. WTLS is needed because mobile networks do not provide complete end-to-end security.
