editor : alpha [82.250.252.26] 2013/08/20 19:20:54 _h1 privacy _p About privacy of mails. {pre When A sends an e-mail to B : 1) the A's file is uploaded to B's ISP-box (Internet Service Provider), 2) then B downloads it from his box to his local computer Actually, as far as I know : 1) the A's file is broken in packets and sent towards B's distant ISP-box 2) these packets percolate (quasi)randomly through the net's nodes 3) and are reassembled in B's distant ISP-box as a plain file 4) then B calls A's file in his distant ISP-box 5) the A's file is broken in packets and sent towards B's local computer 6) these packets percolate (quasi)randomly through the net's nodes 7) and are reassembled in B's local computer as plain file. Note that : 1) the plain file is in the ISP-box, readable by anybody, 2) the sequence "broken + reassemble" is made twice Suppose another protocol : 1) the A's file is broken in packets and sent towards B's distant ISP-box 2) these packets percolate (quasi)randomly through the net's node 3) at a given moment "t", they are stored "such as they are, where they are" in the net's nodes, 4) then B calls A's file in his distant ISP-box 5) the ISP server calls the packets "such as they are, where they are" in the net's nodes, 6) the packets go on percolating (quasi)randomly through the net 7) and are reassembled in B's local computer as plain file. Note that : 1) the net's nodes don't store readable files 2) the sequence "broken + reassemble" is made once If it was possible, a better level of privacy could be reached, and maybe more efficiently. } _p Where is the problem ?
