Finally, any scheme that is "zero knowledge" is effectively worthless - you can just generate a dummy key (or IV) and paste it into your software and generate a valid ticket instantly. Even with a scheme that requires a strong handshake (hardware challenge like Eve or STS, or a challenge like the one used by The Us Government) it does not work as software vendors can just copy the key and generate all the tickets they want. Effective solutions for those problems require the client to have some degree of trust in the server so secure(rhodes) notes or a challenge method like OATH or PGP can be used.
Potential issues include that you are offering to sign practically anything so you need to assume someone will run a chosen plain text and/or chosen ciphertext attacks. That can be mitigated by checking the serial number provided and refusing to handle request from invalid ones as well as refusing to handle more than a given number of queries from a given s/n in an interval (say 2 per year)
In order to successfully break messages that use ECB, IV and CPA cyphers, cryptanalysts must perform several tasks on these types of cyphers. However, the same tasks are also part of the process used to break the system itself.
The first task is to determine the correct key schedule for the cypher. The attacker inputs a set of test message to a faulty implementation of the system, in this case the two final generic text are corrupted. By changing the key schedule in the code, the output changes, but the test message is corrupted the same way and the attacker can see how the resulting output is changed.
The next task is to determine the correct plaintext and the correct cipher. It is important to note that these particular cyphers can both use the ciphertext as the plaintext, and the message can be decrypted as the evenodel encrypted and decrypted decryption keys (as well as the plaintext are the same). 7211a4ac4a
