Ultralight AES Chip Awọn kaadi, Ultralight AES Chip Hotel Room Keys, Ultralight AES Vingard Kaadi, Ultralight AES Chip Tiketi

MIFARE Ultralight AES jẹ kaadi IC smart alailowaya olubasọrọ ti o munadoko ti o munadoko nipasẹ NXP, apẹrẹ fun lopin lilo igba (gẹgẹbi tikẹti gbigbe ati iṣakoso wiwọle hotẹẹli). O ṣe ẹya fifi ẹnọ kọ nkan AES-128 ati awọn ọna aabo imudara, ati ki o ni awọn wọnyi abuda:
Mo. Aabo Awọn ẹya ara ẹrọ
AES-128 ìfàṣẹsí ìsekóòdù: Atilẹyin meji-ọna mẹta-ipele ìfàṣẹsí, dynamically gbogbo awọn bọtini igba, ati idilọwọ wiwọle laigba aṣẹ.
Idaabobo Ijeri odi: Iyan 24-bit counter-ọna kan ati counter pipaṣẹ fi opin si nọmba awọn igbiyanju ijẹrisi ti ko tọ.
Data Idaabobo Idaabobo: Ṣe idaniloju awọn ifiranṣẹ ibaraẹnisọrọ nipasẹ CMAC (Mac-orisun Cipher) lati dena fifọwọkan.
Titiipa bọtini: Ṣe atilẹyin ọna ipamọ bọtini AES ti o ni idaabobo kikọ, ni ibamu pẹlu ibile CRYPTO1 bọtini.
II. Išẹ ati Ibamu
Ibi agbara: 144 baiti EEPROM olumulo iranti, atilẹyin 100,000 kọ mosi fun ọmọ.
Communication Protocol: Ni ibamu pẹlu ISO/IEC 14443 A-2/-3 bošewa, iṣẹ igbohunsafẹfẹ 13.56MHz, gbigbe oṣuwọn 106 kbit / s, ka ijinna to 10cm.
Ibamu: Eto iranti jẹ kanna bi iran iṣaaju MIFARE Ultralight jara, irọrun eto awọn iṣagbega.
Ṣe atilẹyin awọn ID ID ati 7-baiti UIDs fun imudara aabo ikọkọ.
III. Awọn oju iṣẹlẹ elo
Tiketi gbigbe: Rọpo awọn tiketi iwe / awọn koodu QR, atilẹyin nikan-ajo tiketi, olona-ajo tiketi, ati tiketi iṣẹlẹ
Hotel Access Iṣakoso: Ṣepọ pẹlu eto titiipa Assa Abloy Vingard, pese iṣakoso wiwọle to ni aabo si awọn yara alejo ati awọn ohun elo.
Awọn kaadi ẹgbẹ / Awọn sisanwo Iye-Kekere: Dara fun iye owo kekere, ga-aabo, lopin-lilo awọn oju iṣẹlẹ.
