Survey of Manual Cryptosysteas Until about 1966 this course was taken by everyone who wuted to learn about c ryptanalysis--aspirin1 cryptanalysts lin uists traffic analysts reporters and englneers--a most heteroseneous roup It was a 3-week full-ti11e course coverln1 cryptoJ1'aphy and sillple analysis of manual cryptosystems When CA-100 General Cryptanalysis vas written in 1966 all of CA•Oll was incorporated into lt and a considerable IIIIOWlt of new material analysis and theory was added The cou'l'se now introduced a new aiialytic aid the coaputer RYl to cryptanalysis courses Ori- • glnally CA-100 covered both unual and uchine cryptosystas and took 10 weeks full-t lae to teach froa the platform Eventually the two weeks devoted to cipher uchlne• wero split off expanded and acle into a separate 3-week course called CA-120 Survey of Maclline Cryptosystea loavin1 CA-100 as a weeks of aanual cryptosysteu plus llYl A lot of HSA analysts vere trained well by these throe courses llut there were soae probleu with th• due primarily to the fact that the curriculua just pew without mch pl ning One wu a hi1h depee of duplication between CA-011 and CA-100 Students did not know which course to take and the many who took both vere understandably bored by the repetition which also wasted uny training dollars CA-120 in spite of its title SUrvey of Machine Cryptosysteu has not kept up vi th the tlaes 1ta1elln and Wired 'Nheels are well represnted but the Shift Resister imit is woefully inadequate Until recently there w s no prerequisite for CA-120 and the pertinent polyalphabetic inforution fro• CA 100 had to be included a1ain in CA 120 Por students who had taken both CA-011 and CA-100 previously this • eut the third exposure to the sue material ln addition to the probl_ with course content there were teachilll pEObleas as well flle annual heavy student loads for these popular basic courses consuaed a disproportionate uount of instntetor ti ft Typically 71 per cent of the cryptanalysis instructors spent 110st or all of their tlN on these 3 courses This left no tl111--or enersr••to do research and to develop new courses especially soae ur1ently needed to tTain the analysts who need multiple disciplines to work on today's c0111plex proble11s Hov 74 • CRYPTOLOG • Pase 7 IOI SfGPP UMIM JiOP fiGAlil WMIM Self-paced Courses The decision to self-pace s01 1e of the basic CA courses was made in order to deal with such proble11s It provides the opportunity to make many improvements to 1110dernize the contents of the courses and to arrange them in a sequence designed to build up knowledges and skills progressively Self-paced courses insure that everyone gets the sue basic information a boon to teachers of advanced courses who must often reteach what should have been learned in a prerequisite course but was not They also mean an end to the wildly heterogeneous classes which are so frustrating to students and teachers alike I11p0rtant revisions in course content will also result The unnecessary and confusing divislon into cipher and code has been oliainated Code takes its rightful place from the cryptanalytic point of view as a fora of aonoalphabet ic substitution systn Actual-roconstn 1ctlon of tho code after tho initial break-in is not a cryptanalytic process but a cryptolinguistlc one The traditional but to mo unnatural split between manual and machine cryptosystns will bo scrapped and uchine cryptosystems will be taught as Mchanizod polyalphabetic substitution The arithmetic of substitution will be tau1ht in the very first course and superenciphe111ents will be presented as polyalphabetic substitution with numerical cipher alphabets Everyone is now required to learn how to use existing c0111pUter progrlllllS to
