Perfect security: one-time pads. 330 $aOriginally published in the New Mathematical Library almost half a century ago, this charming book explains how to solve cryptograms based on elementary mathematical principles, starting with the Caesar cipher and building up to progressively more sophisticated substitution methods. Todd Feil has updated the book for the technological age by adding two new chapters covering RSA public-key cryptography, one-time pads, and pseudo-random-number generators. Exercises are given throughout the text that will help the reader understand the concepts and practice the techniques presented. Software to ease the drudgery of making the necessary calculations is made available. The book assumes minimal mathematical prerequisites and therefore explains from scratch such concepts as summation notation, matrix multiplication, and modular arithmetic. Even the mathematically sophisticated reader, however, will find some of the exercises challenging. (Answers to the exercises appear in an appendix.) 410 0$aAnneli Lax New Mathematical Library 606 $aCryptography$xMathematics 606 $aCiphers$xMathematics 615 0$aCryptography$xMathematics. 615 0$aCiphers$xMathematics. 676 $a652.80151 700 $aSinkov$b Abraham$f1907-$0770286 701 $aFeil$b Todd$f1951-$054112 712 02$aMathematical Association of America, 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910954622103321 996 $aElementary cryptanalysis$94403593 997 $aUNINA LEADER 02829nam 2200661 a 450 001 9910970497003321 005 20251117115847.0 010 $a1-134-76702-1 010 $a1-134-76703-X 010 $a1-280-13951-X 010 $a0-203-97612-6 024 7 $a10.4324/9780203976128 035 $a(CKB)1000000000002094 035 $a(EBL)240224 035 $a(OCoLC)50853817 035 $a(SSID)ssj0000278637 035 $a(PQKBManifestationID)11210625 035 $a(PQKBTitleCode)TC0000278637 035 $a(PQKBWorkID)10246220 035 $a(PQKB)10211403 035 $a(SSID)ssj0000137915 035 $a(PQKBManifestationID)12002740 035 $a(PQKBTitleCode)TC0000137915 035 $a(PQKBWorkID)10097076 035 $a(PQKB)11317918 035 $a(MiAaPQ)EBC240224 035 $a(EXLCZ)991000000000002094 100 $a20001211d2000 uy 0 101 0 $aeng 135 $aur|n|---||||| 181 $ctxt 182 $cc 183 $acr 200 10$aDevelopment geography /$fRupert Hodder 205 $a1st ed. 210 $aLondon $cRoutledge$d2000 215 $a1 online resource (201 p.) 225 1 $aRoutledge contemporary human geography series 300 $aDescription based upon print version of record. 311 08$a0-415-14211-3 311 08$a0-415-14210-5 320 $aIncludes bibliographical references and index. 327 $aCONTENTS; List of plates; List of figures; List of tables; List of boxes; Acknowledgements; List of abbreviations; 1 Approaches to development; 2 Population and development; 3 Culture and development; 4 Rural-agricultural development; 5 Urban-industrial development; 6 The state context: China and Brazil; 7 Regional groupings, trade and aid; 8 Globalisation; Epilogue; Bibliography; Index 330 $aDevelopment Geography is an informative and vibrant introductory level text, with a wealth of contrasting case-studies and illustrations. Written to stimulate critical thought and discussion about development, it does not assume any clear-cut distinction between 'developed' and 'developing' parts of the world. Case-studies highlight the problems and possible solutions at local, national and international scales. These include:* food production in Senegal* Disney in China* Hurricane Mitch in Honduras* corruption in Bulgaria* further studies from Russia, Bangladesh a 410 0$aRoutledge contemporary human geography series. 606 $aEconomic development 606 $aEconomic geography 615 0$aEconomic development. 615 0$aEconomic geography. 676 $a338.9 700 $aHodder$b Rupert$0148067 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910970497003321 996 $aDevelopment geography$912695 997 $aUNINA
