nfc - DESfire EV1 AES authentication no reply -

-

i'm trying authenticate desfire ev1 card, card doesn't reply. before trying authenticate, i've formatted card , created new application, selected new application , need authenticate before creating file.

here's communcation format fail:

format card start on bsp_mifare --> 0b 01 90 fc 00 00 00 (tranceive, 56 bits) bsp_mifare <-- fa 01 01 (24 bits) bsp_mifare --> fa 01 01 (tranceive, 24 bits) bsp_mifare <-- fa 01 01 (24 bits) bsp_mifare --> fa 01 01 (tranceive, 24 bits) bsp_mifare <-- fa 01 01 (24 bits) bsp_mifare --> fa 01 01 (tranceive, 24 bits) bsp_mifare <-- fa 01 01 (24 bits) bsp_mifare --> fa 01 01 (tranceive, 24 bits) bsp_mifare <-- fa 01 01 (24 bits) bsp_mifare --> fa 01 01 (tranceive, 24 bits) bsp_mifare <-- 0b 01 91 00 (32 bits) bsp_mifare --> 0a 01 90 0a 00 00 01 00 00 (tranceive, 72 bits) bsp_mifare <-- 0a 01 ad 51 73 29 dc 6e 33 cf 91 af (96 bits) bsp_mifare --> 0b 01 90 af 00 00 10 2e 4a 13 9c a9 d4 23 61 25 28 48 ce 2c 73 2c 70 00 (tranceive, 192 bits) bsp_mifare <-- 0b 01 fc 25 2e 4f 00 c3 86 e8 91 00 (96 bits) create application default aes key bsp_mifare --> 0a 01 90 ca 00 00 05 33 22 11 0b 84 00 (tranceive, 104 bits) bsp_mifare <-- 0a 01 91 00 (32 bits) select application... bsp_mifare --> 0b 01 90 5a 00 00 03 33 22 11 00 (tranceive, 88 bits) bsp_mifare <-- 0b 01 91 00 (32 bits) authenticate... bsp_mifare --> 0a 01 90 aa 00 00 01 00 00 (tranceive, 72 bits) bsp_mifare <-- (0 bits) bsp_mifare --> 0a 01 90 aa 00 00 01 00 00 (tranceive, 72 bits) bsp_mifare <-- (0 bits) failed authenticate null aes key: 0x00

if try authenticate invalid key number (e.g. 6 when num_keys 4), "no such key" reply, card @ least partly understanding request.

so question is, what's wrong "start of authentication" command:

bsp_mifare --> 0a 01 90 aa 00 00 01 00 00 (tranceive, 72 bits)

(the data shown raw data, including wrapping. actual native command "aa 00").

turns out hardware failure: aes commands need more power des/crypto1 ones (50% more), antenna failed deliver @ reading range testing with. moving card closer fixed problem.

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2

i need place custom knob image shadow uislider. far have image of 38x38, of there region defines shadow of knob. now while using image, when slide knob extreme ends actual knob not able cover end points, hence end points visible under transparent region of knob image this code using customize uislider uiimage *slidebtimg = [uiimage imagenamed:sliderknobimg]; [self.ratingslider setthumbimage:slidebtimg forstate:uicontrolstatenormal]; [self.ratingslider setthumbimage:slidebtimg forstate:uicontrolstatehighlighted]; how can implement custom knob shadow beneath it, covering end points?? look inside uislider.h , there methods let customize slider knob , track needed.
