According to time of operation, the buses are divided as follows : numbers that start with " 2 " are morning and evening rush hour buses, numbers that start with 3 are night buses ; according to location, buses are divided as follows : puxi buses, pudong buses, buses that cross the river including tunnel and bridge lines, and suburban area buses [ 700s & 900s ] ; according to payment method, the buses are divided into : single - ticket rmb 1 ( lines of 13 kilometer or less from end to end ) and rmb 1. 5 ( lines of 13 kilometers or more from end to end ) ticket - sellerless buses ( most two digit city buses and three digits buses starting with " 1 ", " 2 ", " 7 " are of this kind ; no change will be made, but terminal stations and hubs will have rmb 1 and rmb 1. 5 ticket booklets for sale, 50 non - refundable tickets per booklet ), and also single ticket rmb 2 air - conditioned buses and scaled - price ticket special lines ( including specialty coach lines starting with " 5 ", pudong specialty lines starting with " 6 ", mid - size coaches that start with " 8 ", double - decker buses and air - conditioned coaches that start with " 9 ", as well as the ten air - conditioned tourism lines [ and airport buses ] )
按運營時間分，有：日間公交車、 「 2 」字頭的早晚高峰車和「 3 」字頭的夜宵車；按地域范圍分，有浦西的、浦東的、過江的（含大橋、隧道線）和郊區線；按票務方式分，有單一票價1元（全程13公里以下的線路）或1 . 5元（全程超13公里的線路）的無人售票車（市內公交號碼為兩位數的或三位數中「 1 」字頭、 「 2 」字頭、 「 7 」字頭的線路絕大多數是無人售票車，自備零錢，不找零，公交終點站、各主要交通樞紐均有1元和1元5角兩種面值的公交預售票出售，每本50張，售出不退） ，還有單一票價2元的空調車和多級票價的專線車（有「 5 」字頭的大巴專線、 「 6 」字頭的浦東專線車、 「 8 」字頭的中巴專線和「 9 」字頭的雙層車或空調大巴，還有十條空調旅遊專線） 。The biggest difference between traditional card and information - stored card is that the latter not only has information printed on the card ' s surface, but also save more information in the bar code or ic of the card
這類證件較傳統的身份證件最大不同之處在於，它所記錄的信息不僅僅以文字或圖像的形式直接顯示在證件表面，而是有大部分的信息存儲在卡上的條形碼或晶元之中。In the end, quick implementation of kasumi, f8 and f9 are simulated under the condition of windows 98 with celeron 633 and 128m memory, the simulation data show that the f8 algorithm is capable of achieving the encryption rate up to 1. 9mbit / s, while f9 algorithm only takes 20ms to compute the mac with the length of 5114 bits, both of which can reach the basica requirement of 3g
在本文的最後我們對kasumi ， f8演算法和f9演算法的快速實現進行了具體的模擬， f8演算法的具體實現是在windows98 ，賽揚633mhz和128m內存的環境下其加密速率可以達到1 . 9mbps ，而f9演算法在同樣的條件下計算5114比特的字元串的消息認證碼所需時間僅為20毫秒，這些速率基本上可以滿足3g中高速率傳輸的要求。Firstly, we generalize and analyze the advantages and present research of elliptic curve cryptography ; secondly, we study the basic theory of the ecc ; thirdly, we illustrate the safety of the ecc and discuss the elliptic curve key agreement scheme, elliptic curve encryption scheme and elliptic curve digital signature algorithm ; fourthly, we study fast algorithms of the multiplication and inversion multiplication of the element of in the underlying finite field f2m whose characteristic is two represented by the two basis of optimal normal basis and polynomial basis. we make improvements to the fast algorithm of the polynomial basis multiplication by hankerson and base on the experiments, we describe the properties and compare the advantages of the multiplication and inversion multiplication of the elements in f2m field under optimal normal bases and polynomial basis. results concluding from the study car be used as references in the realization of the elliptic curve cryptosystem ; fifthly, we overview the current fast algorithm of point multiplication, improve the fix base point comb algorithm, advance the speed of the whole system and remark the advantages and disadvantages of the popular algorithms based upon the experimental datas ; sixthly we realize the algorithm library of elliptic curve cryptography based on the f2m. only change slightly in our algorithm library can we realize the ecdh, eces, ecdsa based onf2m of anysize ; seventhly, we realize the ecc on two secure elliptic curves, including ecdh, eces, ecdsa
本文首先介紹並分析了橢圓曲線密碼體制的優點及研究現狀；其次研究了橢圓曲線密碼體制的基本理論；第三，分析了橢圓曲線密碼的安全性並介紹了密鑰共享，加密，數字簽名等橢圓曲線密碼體制；第四，深入研究了特徵為2的有限域f _ 2m中的元素在多項式基和最優正規基表示下的乘法運算和乘法逆運算的快速演算法，並對hankerson等人提出的多項式基下的乘法運算的快速演算法作了改進，而且在實驗的基礎上不僅分析研究了f _ 2m域中元素在多項式基和最優正規基表示下的乘法和乘法逆運算的性能，還對這兩種基表示下的f _ 2m域中元素運算效率的優劣作了比較和研究，所得的結論可供在實現橢圓曲線密碼體制時參考；第五，研究了目前流行的計算橢圓曲線標量乘法的快速演算法，同時改進了固定基點梳形法，提高了整個系統的速度，並在實驗的基礎上分析研究了流行演算法的優劣；第六，實現了基於f _ 2m的橢圓曲線密碼體制的演算法庫，在我們的演算法庫中只需稍微改變便能實現基於任意尺寸的f _ 2m上的ecdh ， eces ， ecdsa等橢圓曲線密碼體制；第七，實現了兩條安全橢圓曲線上的橢圓曲線密碼體制，包括ecdh ， eces ， ecdsa 。Bar code is one kind of sign composed regularly with a group of bars and spaces, which is used to represent the combination information of characters, numbers and symbols
條碼是一組按一定編碼規則排列的條、空符號組合，用以表示一定的字元、數字及符號組成的信息。The article number is represented by a machine - readable symbol, printed to well - defined specifications. article numbers for consumer units are always represented by standard ean - 13 symbols - for 13 digit numbers and ean - 8 for 8 - digit number. the bar code consists of a series of light and dark vertical parallel " bars " and is normally incorporated as part of the original packaging design
