satellite - Using SSL over an Iridium connection -

-

i using iridium (satellite constellation) modem exchange information in world. main goal send messages on internet. messages might include confidential information , wondering possible ways secure line.i thought ssl.

the bandwidth of iridium estimated @ 0.3kb/s (300 bytes / sec).

q: solution (ssl) viable such slow bandwidth ?

i know handshake (ssl setup) includes lots of data (~5kb) not problem wait 1 minute have connection established. question refers next step, when comes send messages, cause major slowdown in exchanges ?.

encryption should not cause slowdown.

if using smtp send messge, check whether smtp server accepts secure connections. e-mail clients can connect smtp server via ssl/tls encrypted smtp (it uses port 465).

if worry contents of email itself, encrytion before sending advised imho. see e.g. https://guardianproject.info/code/gnupg/
