What does WTLS stand for?

• A. Wireless Transportation Layer Security
• B. Wireless Transport Layer Security
• C. Wireless TLS Layer Security
• D. Wireless Transported Layer Security

Answer: (A)

Wireless Transport Layer Security explains the origin of WTLS by mirroring TLS, but adapted for wireless data. The “Transport Layer” part refers to the OSI/TCP/IP transport layer, the layer where TLS normally operates to secure data in transit. In the wireless context, WTLS provides confidentiality, integrity, and authentication for data exchanged between a mobile device and the gateway in the WAP stack, with adjustments for wireless constraints like limited bandwidth and higher latency. The form with “Transportation” is not the standard expansion; TLS stands for Transport Layer Security, not Transportation. Other options misstate the terminology or the word order, so the correct expansion is Wireless Transport Layer Security.
