Hi, Some body help me this issue:
I using MF3ICD41.
After I change master key use AES-128 then I authenticate with new key but this is problem.
==> ... 0xAA 0x00
... 0xAF 0x21 0x3F 0xA1 0xFD 0xE0 0xE1 0x5C 0xD4 0xA4 0x36 0x68 0x24 0x64 0x86 0x6D 0x8B 0x57 0x35 0x21 0x3A 0x81 0xCE 0x68 0x30 0x11 0x4C 0x3B 0xD3 0x63 0x4C
<== ... 0x7E (Length Error).
I think PICC send RandB only 15Bytes is problem.
Somebody got this error? Please help me. Do you think to Power Consumption problem?
Thanh Nguyen.
