Defeating an Incription Algorithm

The goal of the attacker is to get access to an inscription key. They don't have it. So they hve to use various methods available if they have access to doloress or christ as data. Theres two type of attacks that they may a be most applicable to the current situation, the chosen plane text attack and the chosen cypher tax attack. This model may sound ludicrous at first, because if you can decrypt, what else do you need? But decripting something is not always enough to break a system. For example, some vidia protection devices allow attackers to perform incribing queries and decription queries using the device as chip.
