Hi,

would like to know if JCOP21id is fully supported by Muscle regarding
the secure messaging/channel requirement? Is this protocol implemented
in Muscle? If it is, where in the code?

No.

I have a number of JCOP21id cards that I need to fully suport.

What is your task?

You want to use the secure channels? What means need? Is the integrity and confidentiality really important? Is the card user the same like the card issuer (Else this does not work, because the user has access to the secret keys of the card issuer and can install untrusted applications. Aside from this, this means that the user has to enter every time these secret keys or at least a pass phrase for the encryption of the keys (if these keys are stored encrypt on a media) (storing this keys in plain text would violate any idea of this system.) at each computer system. At the keyboard. In an untrusted environment the system knows the keys and the whole secure channel system is broken ...)

If you are adept with this technology then you certainly know all the above things and an adaption of MuscleCard is possible.
