Hi<div><br></div><div>I am studying your system. First, it is a very nice system.</div><div>I have confusion on the storage availability:</div><div><span class="Apple-style-span" style="font-family: Calibri, sans-serif; font-size: 14px; ">"Users
do rely on storage servers for <i>availability</i>. The cipher text is
erasure-coded and distributed across <i>N</i> storage servers (the default value
for <i>N</i> is 10) so that it can be recovered from any <i>K</i> of these
servers (the default value of <i>K</i> is 3). Therefore only the simultaneous
failure of <i>N-K+1</i> (with the defaults, 8) servers can make the data
unavailable."</span></div><div><span class="Apple-style-span" style="font-family: Calibri, sans-serif; font-size: 14px; ">I do not know how it works, how a file is encrypted and distributed among these server. </span><span class="Apple-style-span" style="font-family: Calibri, sans-serif; font-size: 14px; ">Could anyone briefly explain it to me?</span></div>
