IC Card 又有時稱為Smart Card.它是先將IC封裝成mole，然後嵌入到PVC等類型的塑料或其他材料製成的卡片上得到的。 IC Card also called Smart Card, which is a first IC packaging mole, and then embedded in PVC, and other types of plastic or other materials are on the cards. 根據其與外部通信方式可以分成兩類: 接觸式IC卡,射頻IC卡。 According to its external communications can be divided into two categories: contactless IC card, RF IC card.

一、接觸式IC卡 First, contactless IC card

接觸式IC卡通過觸點與外界實現電氣接觸進行數據交換.其物理、電氣特性應遵循ISO7816-1/2/3協議。 Contactless IC card through contact with the outside world to achieve electrical contact data exchange. Its physical and electrical characteristics should follow ISO7816-1/2/3 agreement. ISO7816－1/2/3詳細描述了接觸式IC卡的物理尺寸、卡觸點功能、通信協議等物理、電氣規范。 ISO7816-1/2/3 detailed description of the contactless IC card physical size, function cards contacts, communication protocols, such as physics, electrical specifications. 根據接觸式IC卡的數據加密情況可以將接觸式IC卡大致分為三類： 存儲卡 、簡單加密邏輯卡、 CPU卡 。 According to the contactless IC card data can be encrypted contactless IC card will be roughly divided into three categories: memory cards, simple encryption logic card, CPU card.

1、 存儲卡實際上就是普通的EEPROM，不過是封裝成mole嵌入到卡片上了而已。 1, memory card is actually an ordinary EEPROM, but is packaged as mole embedded in the card only. 只要實現電氣接觸就可以對其內部數據進行無條件訪問(當然需要根據該型號EEPROM的電氣規范了)。 As long as we can achieve electrical contact between its internal data unconditional visit (of course, in accordance with the model of the electrical specifications of the EEPROM). 這種卡安全性幾乎為0，所以只能用於一些對安全性不作要求的場合。 This card security almost to zero, so some can only be used for the safety of not request occasions.

2、帶簡單加密邏輯的IC卡內部除了常見的EEPROM/EPROM/ROM類型的存儲器外，還帶有一專門設計的加密邏輯電路，用以防護敏感嘈?數據區。 2, with a simple encryption logic IC card in addition to common internal EEPROM / EPROM / ROM type memory, but also with a specially designed encryption logic circuits for the protection sensitive Cao? Data area. 通常是兩個位元組的口令字，口令字以明文的形式遞交給卡片，卡片效驗通過後才允許對保護數據區訪問。 Usually two byte password, password in the form of the word to express submitted to the card through the card-tested after allowing for data protection zone visit.

3、至於CPU卡當然其內部有一內嵌CPU了，這種卡一般都採用國際上通用的DES、RSA等加密演算法對數據進行保護。 3, as of course its internal CPU card embedded with a CPU, and this kind of cards are generally used international generic DES, RSA encryption algorithm such as data protection. 為了加快數據交換的速度，往往還擁有內嵌的RSA演算法協處理器等。 In order to accelerate the speed of data exchange, often with embedded RSA algorithm coprocessor, and other. CPU卡的CPU一般為8031/51系列單片機的內核，也有採用其他內核的。 CPU CPU cards generally 8031/51 Series MCU core, but also the use of other cores. 卡內通常有一固化的COS（卡片操作系統），實現卡內的數據管理。 Cards usually have a curable COS (cards operating system), the realization of the card data management. 這種卡進行密碼效驗時密碼是不以明文出現在通信線上的。 This card password-tested when the password is not explicitly appear in the online communication. 另外為了提高其安全性以更適合於金融等應用場合，卡片的IC在設計時也採用了一些諸如匯流排加擾等反剖析措施，防止激光切割剖析? In addition to improving their safety in a more suited to financial applications, the IC card is used in the design of the bus, such as some scrambling, and other anti-analysis measures to prevent the laser cutting analysis?

二、射頻IC卡 Second, RF IC card

射頻IC卡通過卡內的線圈與外界進行射頻通信實現數據交換.這種IC卡有的帶有內部電池，可以工作3年或是幾年，也有的靠線圈的感應電流工作。 RF IC card through the card in the RF coil communication with the outside world for achieving data exchange. Some of this IC card with internal battery, can work a few years or three years, and some are on the inction coil current work. 由於線圈的體積決定了感應電流的強度從而決定了其有效作用距離，所以有的公司設計的射頻IC卡允許用戶自己設計、繞制線圈。 As the size of the coil determines the intensity of the inced current to determine its effective distance, so some companies design of RF IC card allows users to design their own, winding coils. 這種卡經常用於諸如身份鑒別等場合。 This card is frequently used as identification, and so on.

三、關於電話IC卡 Third, on the telephone IC card

電話IC卡應該算是屬於簡單邏輯加密卡。 Telephone IC card is simple logic should be considered encryption card. 不過它的設計又與進行口令字效驗的簡單加密邏輯卡不同,因此筆者認為有必要對其進行簡單的單獨介紹。 But it is designed with a password-tested a simple encryption card different logic, I believe that it is necessary to introce a simple single. 對於簡單加密邏輯卡，當寫口令效驗通過後可以對數據區進行寫操作，這意味者可以對數據進行任意改動。 For simple encryption logic card, when write-tested through the password can be concted on the data write operation, it will mean that the data can be arbitrarily changed. 電話卡則不允許有這樣的操作(否則卡上的錢不就可以改了?)，所以電話卡設計成一形同算盤方式計數的計數器，卡片發行後，該計數器只能減，不能加，換言之，只能扣錢，不能加錢，用完後卡片作廢。 Phone cards do not allow the operation of this (otherwise, the money is not on the card can be changed?), Telephone cards designed to counter a way of thinking is tantamount to counter card issuers, the counter will only decrease, not increase, in other words, only Koujian can, and the money can not be used after the card void. 那位要問了：那不是隨便搞張同型號的卡就可以打「免費」電話了？ He would ask: it is not easily engage with models of the card can be a "free" phone? 非也，電話卡有一ROM區，生產廠商預先將大宗客戶編號寫在裡面了。 No, there is a calling card ROM, manufacturers, in advance bulk of the code written on the inside. 卡片出廠後就無法改動了。 Cards can not be altered after the factory. 另外還有一區域是供用戶（如電信局）添的，用戶填寫完後可以將保護熔絲熔斷，使該用戶數據區不可更改。 There is also a region is for users (such as the bureau) Tim, users can be protected after completing the fuse links, the user can not change the data area. 所以IC卡電話靠這兩個號就可以將非法卡據之門外。 Therefore, IC card on the phone, these two cards can be illegal according to the gateway. 但是從技術的角度上講現行的IC卡電話系統還是不完善，還是有可行辦法攻擊當前的IC卡電話系統。 However, from a technical perspective, the existing telephone system or IC card imperfect, there are still options attack the current IC card telephone system. 當然筆者又不想來個什麼高科技犯罪之類的舉動，對於這種危害公共安全的問題就不再多言了。 Of course, what the author does not want high-tech crimes such moves, such endangering public safety issues will not say more about. 如果電話IC卡採用CPU卡其安全性可就上台階了,當然成本也就上台階了:-)。 If the telephone IC cards, CPU khaki on the security level, of course, it costs a level :-).

四、IC Card 生產商 4, IC Card manufacturers

比較著名的IC Card生產製造商有Gemplus、Siemens、Philip、Atmel等。 Comparison of the famous IC Card manufacturers have Gemplus, Siemens, Philip, such as Atmel. 它們提供各種型號的IC Card,客戶也可以定做。 They provide various types of IC Card, customers can be customized. 另外國內這幾年雨後春荀般冒出了許多所謂的IC卡製作商，實際上它們只是完成ICmole到塑料基片的封裝以及印刷工作。 Another domestic few years after the rain this spring Xun as the emergence of many so-called IC card maker, in fact they merely completed ICmole to plastic substrate packaging and printing work. 哈工大曾經設計出過國內第一片IC卡晶元。 HIT has designed the first-ever domestic IC card chips.

㈦ SMT術語中燒錄IC英文怎麼翻譯

IC Programming

燒錄器英文名為PROGRAMMER，有人叫WRITER，更早期有人叫BURNER，這種機器是用來燒錄〔PROGRAM〕一種稱為可燒錄的IC〔PROGRAMABLE IC〕，可燒錄這些IC內部的CELL〔細胞〕資料，造成不同的功能。

自從可燒錄的IC出現後，設計者只要准備一種IC便可把它燒錄成不同功能的IC，備料者只採購一種IC即可，備料方便，但須准備燒錄器去燒錄它。

IC需要燒錄的原因

第一，因為電子產品中有單片機或者ARM的控制器。在生產過程中，最開始控制晶元當中是沒有任何程序的，為了單片機或者ARM晶元按照我們設計的功能執行操作，則需要將工程編寫好的程序執行文件，燒錄到電子產品的控制器晶元當中。

第二，需要燒錄對應參數。當單片機或者ARM程序燒錄後，有時候為了保密，可以通過串口或者USB等介面，需要對程序進行加密參數設定，或者燒錄一部分參數，比如wifi模組的IP地址和埠的數據，都是為了保證電子產品能夠正常運行。

第三，燒錄文件，比如字型檔、圖片、鈴聲、動畫等文件。現在很多電子產品當中，都有顯示屏幕，為了給用戶增加優越的用戶體驗，需要將提前處理的高清照片保證到單片機或者ARM系統存儲當中，字型檔文件是為了用戶輸入漢字調用的電子產品底層文件。

總的來說，IC收錄這一道程序的目的在於保證單片機系統或者ARM晶元的正常運行，以及安全運行中必不可少的文件和參數。

㈧ 加密IC的介紹

加密IC，主要用來保護燒進Flash裡面的程序即使被盜版者讀走， 在非法板上也不能運行， 從而達到保護自己勞動成果的目的。

㈨ 「加密」英語怎麼寫的

同學你好，很高興為您解答！

數據加密Data Encryption

在計算機安全領域，將數據轉化成無法理解的形式，使人無法得到原來的數據或只能通過解密過程得到原來的數據，這一過程就是數據加密。
