Digital futures - the catastrophic edge

re: # parties != 1 knowing secrets The secrets in cryptography are too long to be memorized. Therefore, some computer hardware will need to be the storage container. Secure containers for such secrets can be constructed at much less cost than the value of having the secret escape. Since secrets come in different levels of value, so will containers. Since the secrets are data, they can be backed up as well, with a variety of redundancy mechanisms and social constraints. One can use encrypted data with human-recallable pass phrase (as PGP secret keys) or secret sharing to multiple trustees, or a combination. Eric
