Well, I guess in order to run assembly requires at least one permission, that is permission to execute. So what you probably need is the following:

[assembly: SecurityPermissionAttribute(SecurityAction.RequestMinimum, Execution = true)]
[assembly:PermissionSetAttribute(SecurityAction.RequestOptional, Unrestricted = false)] // Note that it is FALSE here

Also, depending on the version of the Runtime, it may happen that the single attribute you used below could be just ignored, there were couple of weirdnesses in declarative attributes handling for such corner cases [I beleive they are fixed now].

If you truly need to refuse even execution for some reason, replace the first line with this:

[assembly:PermissionSetAttribute(SecurityAction.RequestMinimum, Unrestricted = false)]
