2. Opening Remarks b;y: Chdrman. 

-I'he Chairman said: 11'l'his meeting is the formal opening of the 1953 

'ommunications Security Conference and I should like to extend a very warm welcome 

tio the U.S. team. Some of you have in re.Ct been working together for the past 

f'o'rtnight having informal talks, which I understond have been of great benefit; 

ve now come to considering formally all that you have been discussing informally. 

"v~'hen, in 1952, it was recommended tha.t tho Conference should take place in June of 

this year in London we had in mind that you would be able to see somo of the

events connected with the Coronation. Owing to the shortage of hotel 

accom.~odation, however, this was not possible end it was decided to postpone th~ 

Conf0rence until October. We are very glad to welcome you here and hope this 

Conf0rence will be very successful end th.at y~u will enjoy yo~r visit to us. 

The aim of the Conference is tc achieve n very wide agreement on aJ.l 

aspects of communications security ruid it is hoped thnt, from the full end frank 

discussions between experts,much benefit will be derived •. The ~xchange of details 

of work that he.a been going on 3,,000 miles _apart will be of great mutual interest. 

and in the clash of minds you will get the best answer. I would like to say that 

we in this country are S·3ricusly perturbed at the ste..te of cur communications 

security as distinct from cryptograph;tc security. I am inf~rmed that our 

strindards compare very unf'avcure.bly with "thcise of some other countri.::s. 

The Cypher Policy Board1 of which I am Chairman, has now materially. enlarged 

its terms of reference and has brought into its main policy-making committee the 

three Service Directors of Intelligence; it has enlargei .. -its Secretariat, 

established it as an ..:'lgency and appointed I _as Director of th.at i"i.gency. 

I !haagre·······a:·······t···· ... ex:p· .. e··r·····i···.e··.n·c· e in signal, intelligence e.rid supply matters • . As I _ laid not formally join t ili;i:enc until to-da the Conference 

wi 1 be coriduc ed on the U.K~ sidejJ I hope that this 

1953 Conference will, be very success :t. oμ.r U.S. friends 

will .enjoy their stay in England. 11

3. Remarks by Mr. W.Ft.. Friea.~an (Head 9f U • .S.j)el~gation) 

Mr. ~,riedman replied: "JHrst I would like to sey en behalf of my teom how much 

we appreciate your cordial welcome. We are very gle.d. to be here and incidentally· 

I shall put in a request that we get full marks for bringing suet). lovely weather 

with ua. Seeing London is a great pleasure to begin with but seeing it undur such 

favourable conditions makes it very mu.ch nicer. Thia is ·Na.4 in the series of these 

Oonferences, which bee;an in October 1950 for the purpose of surveying certain 

features of communications s·ecuri ty of interest beth to your Government and to mine. 

The· purpose of course is to provide a mechanism for exchanging technical informaticn 

and keeping in step to ensure that we he.we adequate meons 'With which to communicate 

securely. I e.rn one of the old timers in our group and in 1941 We\ were confronted 

with the immediate necessity for ccmbined communications in a• high grade system. 

There woa a. very serious lack of a secure Combined. system. You had your high gro.de 

ma.chine llild we had ours but they could not interw.Jrk •. How se:d::ms\ this WB.s I harcUy 

ne(}d point 01,lt to all those present. In fact I may aey that that lack occasioned 

the loss of'many lives and of millions of pounds sterling in material.. We must 

ensure that this does not happen e.go.in. 

This Conference is especially concerned with several requi.rements. :inrst of 

.::mr communicators and.second of our intej..lisence community. -It was originally 

decided. to l).old this Conference in Jun~ but this was postponed. owing\to the 

Coronation and also because we hoped t·o have more clearly befote us t.he requireme:ots 

of Ni.TO. Menticnin8 the N.t!TO requirements brings to nrj mind the dise~e to which I 

ho.ve ar.•plied the te~m 11 cryptclogic schizophrenia. 11 On the one hand m~ of us are 

concerned with the provision of secure means for compiunications, on the ether haru.1, 

pa.rt of our organization has a natural reluctance to this course of action. .l~ f'or 

myself I have learned how to handlP. some of the symptoms of that illness; I hope 

the same is true as to the others present. 

The work of Phases I and II of the Conference has been ,::ree.tly facilito.teJ. by 

the informal discussions which have been held in the last two weeks. The two 

Phc·.ses were in the background of the mincls of' the perf Q:: who E. at around\··.t. he table 

at thes~ informol discussi:ms nnd I am quite sure, a.a ___ _,......__ _has er_t;'res.aed, trua,.t 

these inf1·rmal meetings ore very, very useful things. is, "Wever, a question 

for Qisoussion whether we want these informal discussions to contllnle th:l.r~resent 

f0rm.. I will not spena. ·ony more time on that now end again I o.gree witn-J _ I 

as to the great vol.ue of these Conferences for combined communications en · so for·

I listened with e;rea.t interest to what I lhoo to sey ,a.bout the need. 

for improvea cominunica.tions security in the wiaest sense·. I may sa:y that personally 

I have been considerably ~listressea about _the things a.t which he hinted in his 

ver:y brief remark ".'.ln that point. I feel that we are hen.dine information
