![]() ![]() Many combinations are valid here (all of them will start with 6x or 9x). When an ISO7816-compliant smartcard receives a valid 5-byte header from its host, it is required to send back an acknowledgment based on the value of the INS byte to inform the host that it is ready to receive the remainder of the message.Īfter an ISO7816-compliant smartcard has finished processing a packet, it must send a two-byte status word to the host device, informing the host device of the outcome of the transaction. This byte is used to tell the smartcard how many more bytes will be sent to it to complete the message (not counting the ACK and SW (see below)). The fifth byte of an ISO7816-compliant message. The fourth byte of an ISO7816-compliant message. The third byte of an ISO7816-compliant message. This byte can be any value, although only some values are processed as valid instructions by the smartcard. The second byte of an ISO7816-compliant message. The only valid Instruction Class is DD unlike Eurocrypt which supports both 87 and CA. The first byte of an ISO7816-compliant message. The Conax system complies with the ISO7816 standard for packet structure and protocol, using 5 byte command headers of the form: This mean the ATR does not identify the cardholder. The 3 masked bytes can vary, but not necessarily different for each smartcard. ![]() Relates to Direct Convention (least significant bit first). The card sends an Answer-To-Reset sequence of bytes (ATR) which tells the Decoder information about the behaviour of the card itself, such as transmission parameters, manufacturing details etc. When you insert the card into the decoder, the decoder sets the RST line low for a period of time as per the ISO7816 standard, then sets it high and waits for the card to respond. ![]() Quais os sistemas de Conax mais conhecidos?Ĭonax -Lançamento em 1992 porem em 1997 fica mais conhecida com lançamento para DVB.Ĭonax CAS3 -em funcionamento em 2001 "Hacked"Ĭonax CAS5 -Lançamento em 2002 não tenho conhecimento de que foi hacked.Ĭonax CAS7 -Lançamento em 2004 neste momento este sistema ainda não foi hacked e é o ultimo sistema da Conax.
