Here is the 2 APDUs that get sent under linux: 80500300080102030405060708 00C000001C this yields: 611C [1C bytes waiting] 00020000000000000000030200528EDDBD4CFAE5179BF9E427D999A89000 this breaks down into 00020000000000000000 - key diversification data 0302 - key information 0052 - sequence counter 8EDDBD4CFAE5 - card challenge 179BF9E427D999A8 - card cryptogram 9000 - result code (okay) And each time I execute these APDUs I get exactly the same result, where the card challenge section *should* be random. Under windows: 80500300080102030405060708 00C000001C yields: 611C 00020000000000000000030200267DAEA944AAA065ACCCB2C9654A059000 breaks down into 00020000000000000000 - key diversification data 0302 - key information 0026 - sequence counter 7DAEA944AAA0 - card challenge 65ACCCB2C9654A05 - card cryptogram 9000 - okay when run multiple times, the sequence counter is incremented, and the card challenge and card cryptograms are different. Its the same reader and card each time.
