Ideas• Mechanism to ensure complete
transmission of all images (date, messages…) on the recipient site
• Also mechanism to ensure complete transmission for the sender (by receipt from recipient)
• Authentification and integrity of messages (signature)
• Supporting MIME Standards[1], esp. Multipart Mail, Message Partial und der Verwendung von X-Tags [1] incl. RFC2045/46 (MIME Part 1&2), RFC3156 (MIME Security with OpenPGP)
Ideas• Supporting secure variants of POP, IMAP…
(optional, may become legal requirement in Germany)
• Encryption according OpenPGP using only the „MUST“-criteria, (ZIP as optional)
• Digitale Signatur (PGP / MIME)– PGP/ GnuPG for Encryption and Signature
acc.to RFC 3156 und RFC 1847 both ways are recommended:
– Encryption and signature in one step (combined method, RFC 3156, Kapitel 6.2)
– Data with seperated signature acc RFC 1847 PGP kompatibel encrypted (encapsulation, RFC 3156, Kap.6.1).
