UDP<br />

This protocol is an non-secure connection. <strong>IP</strong> packets are sent without knowing whether<br />

they are received. Thus, this procedure has a number of disadvantages. If you are not sure<br />

that the information has been received, then greater effort is required to secure this information.<br />

Security mechanisms<br />

● FEC procedure (Forward Error Correction)<br />

In this procedure, every "mandatory message" is given a number of previously compressed<br />

packets. The number of FEC packets sent with the message is indicated in a<br />

supplementary field that can change at any time. To enable the remote station better<br />

to identify the packet sequence, each "mandatory message" is given a "sequence<br />

number".<br />

● Redundancy procedure<br />

In this procedure, additional IFP pages are sent with a "mandatory message". The<br />

number of "redundancy messages" is defined in advance and cannot change during<br />

transmission. The "mandatory message" is given a "sequence number" to enable the<br />

packets to be identified clearly.<br />
