Hello Tomaso!

You are right. That is not part of the RFC 5050 or RFC 4838.

But with some imagination the Bundle Security Protocol is adequate to
check for transmission errors. Each BAB provides data checking and
invalid bundles going to be dropped. If the standard ciphersuite
BAB-HMAC is too complex for your needs, you can define a CRC-like
ciphersuite which does not require any key.

Kind regards,
