java.lang.Object

ch.imvs.sdes4j.srtp.SrtpSessionParam

ch.imvs.sdes4j.srtp.WshSessionParam

All Implemented Interfaces:

SessionParam

public class WshSessionParam
extends SrtpSessionParam

SRTP defines the SRTP-WINDOW-SIZE [RFC3711, Section 3.3.2] parameter to protect against replay attacks. The Window Size Hint (WSH) session parameter provides a hint for how big this window should be to work satisfactorily. The minimum value is 64 [RFC3711]; however, this value may be considered too low for some applications (e.g., video).
