Secure Email Report

PB outlined the work that had been done at Cambridge and Oxford. The 1st quarterly report had been produced and distributed. This will be the format of the final report but will be updated at regular intervals. Comments are welcome.

DM said that he was worried that many institutions are trying to solve the same problem, e.g. generating random numbers used for keys. PB said that this wasn't very difficult. DM then asked how PGP could be modified to accept and external source of random numbers. PB replied that PGP should be able to take this information now. JG suggested it may require a simple modification to the code. PB agreed to look at how this problem can be solved, and look at how others are doing it. This information will be added to the report [Action:PB]

RJH said that for such information to be useful for the start of the 1996-97 academic year, Computer Centres need this information by May/June 1996. PB said that recommendations for a College/University- wide service would not be available until later in 1996. DM remarked that the real problem with a College/University-wide service is how to generate and distribute keys to 5000 students at the beginning of the new academic year.

RJH then said that he thought the next problem to look at would be pass phrases. He suggested that Key-Escrow would be necessary. PB agreed and said that keys should be held centrally in a secure format. Pass phrases would then be the responsibility of the users, probably held on a disc. DM said that he was still worried that institutions would work on this problem in isolation and requested a UK-wide recommendation. DJ suggested that there were two problems: One generating a large number of keys, and secondly keeping Escrow copies of this keys.

PB then went on to discuss other areas of activity. He reported that a CD-ROM with PGP 2.62i would be produced in conjunction with SURFnet, TERENA and others in Europe (possibly DFN). Information contained on such a CD would be binaries, sources, documentation and integration tools. It was hoped that PGP 3 would be available to add to this disc, but this may not be possible. About 5000 copies would be produced, and it is hoped that 2/3 would be sent to each JANET institution.

PB also reported that he had taken charge of the pgp.net DNS domain. This domain contained a set of equal priority MX records pointing to the current set of stable email key servers. JG enquired if PGP documentation would be changed to reflect this new domain. PB responded that he didn't think it would in the short term, but the machines listed in the current documentation actually form servers in the new domain. Within the domain there will be country codes, such as uk.pgp.net. You can also prefix each domain with ftp and WWW. e.g. ftp.uk.pgp.net points to the server at Oxford. JG asked PB about his work on a key lookup server. PB said that he didn't like mail interfaces - he would prefer an on-line system. He said that he had written a PERL script that would contact a WWW server to retrieve keys. He said that this was slow using the current implementation of keys servers since they were not designed to cope with the current 12000 key load. He went on to describe another PERL script that he had written which put keys into an associative array with dbm lookups - this was much faster. He suggested that we needed a DNS like service to do this, but agreed that reverse lookups would be difficult to do.

JG enquired when (a subset of) the protocol to the WWW interface would be made available. PB replied that he had distributed this to any developer that had asked.

AR how would the selection of tools for the CD be made. DJ said that most software that existed would be put onto the disc. Documentation would be made available for the good software, less for the poor software. DJ suggested that WWW pages may be made available on the CD as well. RJH enquired when the CD would be made available, DJ responded that is hoped to distribute it at NetWorkshop '96 or JENC 7 in May 1996.
