Instead of multiple users sharing a key, what if they just shared the passphrase, and the signature done with a passphrase string-to key as in conventional encryption, rather than with an actual key? The passphrase could be changed regularly and put up as a webpage or post, that was simultaneously encrypted to different users' public keys. This way, there would be no revocation issues, as a revoked key could still be used for decryption, and so, some form of repudiable signatures could be achieved. vedaal
