13 cryptobone is the graphical user interface for a secure messaging sys‐
14 tem that makes sure a user's email is always encrypted without burden‐
15 ing the user with complex message key management. Based on a separate
16 daemon, both ease-of-use and security are assured by a novel approach
17 to encryption key management.
18 While the message keys are secured by a daemon running on the Linux
20 machine, additional protection can be achieved by using an external
21 device for storing the encryption keys. This external device can be
22 another Linux computer dedicated to this task or a Beagle Bone or a
23 Raspberry Pi.
24 The Crypto Bone secure messaging system automatically encrypts a mes‐
26 sage with a strong message key, stored in the cryptobone daemon's data
27 base for secrets. Except for an initial registration of a message key
28 for a recipient, the user does not need to remember any of these mes‐
29 sage keys being in use, as the system updates keys when messages are
30 sent out or received.
31 While only strongly encrypted messages are sent out, incoming messages
33 that cannot be decrypted with registered message keys are discarded.
34 In order to transfer encrypted messages the system has to be set up
36 with a working email account used for this purpose only.
