This is no different than suffering a disk crash. That's what backups are for.
At Jim Gray's tribute on the 31st, Bruce Lindsay gave a talk about Jim's formalization of transaction processing enabled online transactions ... i.e. needed trust in the integrity of integrity of transaction as prerequisite to move from manual/paper processes. In the early 90s, when glasshouse and mainframes seeing significant downturn in their use ... with lots of stuff moving off to PCs, there was a study that half of the companies that had a disk failure involving (business) data that wasn't backed up ... filed for bankruptcy within 30 days. The issue was that glasshouse tended to have all sorts of business processes to backup business critical data. Disk failures that lost stuff like billing data had significant impact on cash flow (there was case of large telco that had bug in its nightly backup and when the disk crashed with customer billing data ... they found that there didn't have valid backups). Something similar also showed up in the Key Escrow meetings in the mid-90s with regard to business data that was normally kept in encrypted form ... i.e. would require replicated key backup/storage in order to retrieve data (countermeasure to single point of failure). part of the downfall of key escrow was that it seem to want all keys ... not just infrastructure where business needed to have replicated its own keys. --------------------------------------------------------------------- The Cryptography Mailing List Unsubscribe by sending "unsubscribe cryptography" to [EMAIL PROTECTED]
