comment Can GCM be used in incremental mode?
But isn't the nonce looks like (nonce + counter)? And I will keep counter value on both sender and receiver and use that to encrypt each successive change (i. e. data will only be added, with new counter value each time, no data that already sent will be sent again). Does this still pose security threat? Can you please elaborate? What about OCB, from description it looks like more suited for this thing (cs.ucdavis.edu/~rogaway/ocb/ocb-faq.htm#describe-ocb)? Thanks in advance.
