  1. 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

    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僅分析研究了f _ 2m域中元素在多項式基和最優正規基表下的乘法和乘法逆運算的性,還對這兩種基表下的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實現基於任尺寸的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 。
  2. But carefully to find, there is something absent or more. to be a element of tv journalism, explanations for it are not only for illustration and complement of the vision language, but also for the use of connection, prompt and enrichment. it makes the information of hearing and vision connected so as to widen and deepen the vision for the comprehension of audience

    筆者認為電視稿作為電視新聞的表現元素之一,並僅僅對畫面語言起解說、補充的作用,更重要的是它對于畫面語言有著串聯、提、豐富的義,使聽覺信息與視覺信息有機結合,並延伸和深化畫面內涵,從而拓展視覺的深度和廣度,以便觀眾更好地理解畫面,加強電視新聞的傳播力度。
  3. Nowadays, digital image processing has been an important part of information processing, in numerous applications, especially in astronomy 、 medicine 、 military fields, the authenticity of image data is highly required. but in many image processing systems, image degradation is inevitably avoided owing to image transmission and conversion, such as the image formation 、 scanning and so on. the typical result behaves blurry 、 distortion 、 having noise etc. in order to denoise and improve the image quality, image restoration has an important meaning

    目前,數圖像處理已經成為信息處理科學的一個重要部分,在眾多的圖像處理應用中,尤其是在天學、醫學、軍事應用領域都對圖像數據的真實性有較高的要求,即使日常的圖像通信也要求獲得盡可高的質量,但在各類圖像處理系統中,由於圖像的傳送和轉換,如成像、復制、掃描、傳輸、顯等,可避免的要造成圖像的降質,典型的表現為圖像模糊、失真、有噪聲等,為了去除噪聲、改善圖像質量,圖像恢復具有非常重要的義;除此之外,很多情況下常常要求及時甚至實時地得到真實的圖像數據。
