my name is Julio Herrera Yarleque, I am a graduate of the career of mechanical-electrical engineering, I am doing my thesis with elstern meters elster a1800 , I want to visualize some data, however I understand that the validation process that I do when I send the identification command in hexadeximal (which is EE 01 00 00 00 00 01 20 38 14) the meter responds with a ticket of 8 bytes which using the algorithm that is determined by ANSI INCITS 92 the ticket is encrypted by a key, I understand that they are using the Key ID 00, however I do not know what is the value (I know that they are 8 bytes) I have tried to read the values of the key table (table 45) but I have not found a specific value, I would like to know if it is possible to obtain the key with the ID 00.

best regards
