If an encryption key is not generat

If an encryption key is not generated as part of a known protocol, then it is impossible to tell, in thegeneral case, how many modules may use this encryption key. The limit on the number of same-keyTriple-DES encryptions is set at 216. If the number of modules using this key for encryption is nogreater than 16 then the overall limit of 220 will not be exceeded. In the highly unusual scenario whenmore than 16 modules share the same key, it is likely that at least some of these modules will notperform the number of encryptions that is close to the allocated maximum (216). Even if they did andthe total number of same-key encryptions exceeded 220, it would be difficult for the attacker toincrease the chances of success when the encryptions are performed by the unrelated modules.

增加成功的機會時，加密由無關的模塊進行。

如果加密金鑰不是作為已知協定的一部分生成的，則無法在
一般情況下，有多少模組可以使用此加密金鑰。同鍵數的限制
三重 DES 加密設定為 216。如果使用此金鑰進行加密的模組數為
大於 16，則不超過 220 的總限制。在極不尋常的情況下，當
超過 16 個模組共用同一金鑰，很可能至少其中一些模組不會
執行接近分配最大值 （216） 的加密數。即使他們做了
同金鑰加密的總數超過 220，攻擊者很難
當加密由不相關的模組執行時，增加成功的機會。
