javacard

问题 I have a Javacard which contains a SSD (Supplementary Security Domain) and I want to delete it. Normally when I want to delete an applet or a package from my card, I send the following DELETE APDU command after a successful Mutual Authentication process (No MAC or data field encryption is required and Security Level == 0 is enough for DELETE APDU command): --> 80 E4 00 00 LC 4F <AID Len> <AID> <-- 90 00 The command above works fine for normal applets. But when I put the AID of my SSD in it,

问题 I'm going to delete an existent key from my card's ISD. To do so I sent a DELETE Key APDU command with corresponding KeyID and KeyVersion to the ISD after a successful Mutual Authentication as below: --> 00 A4 04 00 08 A0 00 00 01 51 00 00 00 <-- 6F 5B 84 08 A0 00 00 01 51 00 00 00 A5 4F 73 49 06 07 2A 86 48 86 FC 6B 01 60 0B 06 09 2A 86 48 86 FC 6B 02 02 02 63 09 06 07 2A 86 48 86 FC 6B 03 64 0B 06 09 2A 86 48 86 FC 6B 04 02 55 65 0B 06 09 2A 86 48 86 FC 6B 02 01 03 66 0C 06 0A 2B 06 01 04

问题 I want to use J2A040 JCOP 21-36k java cards to implement a smart card driven bitlocker-to-go solution using gidsapplet and OpenSC but when attempting to put a certificate on the card (certreq -new) I have not been able to get past the "The smart card is not fully personalized for use" error from windows. This is the dump contents with gids-tool: Dumping Files: Found 5 entries in the masterfile Directory: mscp FileIdentifier: 0xa000 File: \cardid FileIdentifier: 0xa012 DataObjectIdentifier:

问题 I'm currently working on my diploma work. Part of the work includes development of JavaCard applet for regular SIM cards. First option is to use JavaCard2.X API and use APDU commands to communicate with the applet. This might be very tricky as I need to develop client-app for android (which will be communicate with this applet) and that is so far possible only trough special - not so user friendly - API called Seek-for-android . (if I'm wrong, please correct me) However, I also came across

问题 An object of class having some data and I am gone write that object into java card. I am having a function that convert hexadecimal data into byte array and then write that data to smart card using java card. While i convert data into hex format i encrypt that data. So i need to convert object of class into hexadecimal. Please tell me how to convert object into Hex format in java. I am using smart card type = contact card using java card 2.2.2 with jcop using apdu. 回答1: Here i am sending you

问题 I would like to know if there is a way of changing the historical bytes automatically as you power your smartcard, in order to have different response if on contact or contactless. In Javacard you can use setATRHistBytes , and also call it depending on the access interface. But the changes would be reflected on next power up of the card. I want to set them intermediately. TA 回答1: Actually the contact-less interface has no attribute named ATR. Because ATR is for contact interface only. The
