Thanks to Adam Back and Ross Anderson the full Zergo Report on encryption use by the NHSnet is online at: http://www.dcs.ex.ac.uk/~aba/ukcrypto/zergo.html (139K) There may be action by HMG to prohibit publication in the UK (and maybe elsewhere) so we've mirrored it at: http://jya.com/zergo-aba.htm Other mirrors encouraged.
