First off, thanks to all the people who replied to my first post. Which, as it turns out needs a bit of clarifying. I am looking for a secure information system for hospital administration. My mother is on the purchasing committee at her place o' employment (she is a Registered Nurse) and asked me some questions about their nascent search for a new information system. They are considering three operating systems all put on 3090's i believe. They are considering CICS, AIX and something merely labeled propietary (UNIX?). Well, I am visceraly familiar with the first two and know of several security problems with both systems. So, when I read on in her literature I found mention of security. All that it said was individual users have individual passwords! HELLO! I immideatly told her that there was or would be a problem. AIX out-of-box is horribly insecure as is any CICS implementation i have seen. I was/am concerned about the probability of a breach. So, my cryptoQuestion is based around *any* possible/existing medical info- rmation protocals in existance. I would prefer a cryptographic protocol, thus my appeal to the list. If none exist, then industrious punks can make a bundle by creating one (Oh yeah! We do write code when were not hissing at Medusa's Head!). Otherwise, I may simply piece together a package from that which already exists. Punks, I must say it is sad to see the state of information security with regard to Medical Information. --Matt ______________________________________________________________________________ In defense of liberty, encrypt for all purposes, civil and professional.
