ARJ reject reasons?

Okay, I added your info to the table. However, it seems like
invalidPermission, rather than securityDenial, should be returned by the
gatekeeper if the endpoint is not allowed to use a service. IOW,
securityDenial refers to the security mechanism, while invalidPermission
refers to the (non-security) services the endpoint was trying to access. I
doubt whether it matters, though. Most endpoints aren't going to behave
differently depending on whether invalidPermission or securityDenial are

Paul and others,

let me shortly explain the purpose of security denial:

H.235 and security profiles say, that this value is returned in the
reject messages whenever the received cryptoTokens are not acceptable
for some security reason. This may occur due to failed authentication,
lack of authorization (= permission) or failed integrity but also as
part of security negotiation when the received crypto parameters are not
acceptable or understood.

Of course there several more reasons why security might fail and the
responder sends security denial: the password/shared secret is invalid
or not available, the endpoint is not allowed to use a service, replay
detected, integrity violation detected, digital signature wrong,
certificate expired....

Kind regards,

Martin Euchner.
