Wireless Transport Layer Security (WTLS)
Definition - What does Wireless Transport Layer Security (WTLS) mean?
Wireless Transport Layer Security (WTLS) refers to the security level for applications that use the Wireless Application Protocol (WAP). The concept behind WTLS is largely based on Transport Layer Security (TLS) version 1.0, which was modified to allow WTLS to provide sufficient privacy management, efficient authorization of data and data integrity while the message is in the transport layer.
Techopedia explains Wireless Transport Layer Security (WTLS)
WLTS was needed because mobile networks were not able to guarantee an end-to-end security of their data. The then available TLS was especially modified for wireless users. Initially, mobile network devices showed issues like low processing ability, limited bandwidth and inadequate memory size. WTLS was designed to overcome these issues and to provide high security to the data. WTLS supports datagrams in low-bandwidth conditions; it also provides an adequate handshake through dynamic key reloading, which makes it possible for encryption keys to be regularly updated during a secure connection time. This encryption method leads to a secure environment for clients and servers to communicate over a secure authenticated connection.
