Hi,
Has anyone used DTLS on Android or is there an open source Java implementation that supports DTLS?
What are my other options for securing UDP traffic on Android ?
Thanks.
A:
DTLS support is not available in pure Java yet. We ended up using OpenSSL through JNI. I doubt you will find anything on Android.
You should use TLS (which means you have to use TCP).

Thanks. I assume you used DTLS of OpenSSL. How was the performance of using OpenSSL using JNI? Is your code open source ?

The project is not open source. Performance is good but we finally decided using DTLS is not worth while. UDP has lots of advantage over TCP, you save the 3 way handshake (4 ms on our network). However, when you add the overhead of TLS, the performance gain between UDP and TCP is not that noticeable.
