<p>Jedine, co je, ze se odsouhlasi, ze protistrana je dany server
bez kontroly a prepne se do daneho sifrovani. Tim to neni bezpecne
.... , ale tvari se jako S. Proto nevyhnutelne vetsina low power
protokolu vede k tomu, ze si nahrajete nejaky klic(heslo) do
zarizeni a do serveru, aby jste tuto identifikaci opustil a
zjednodusil cely proces, pote opustite i to httpS a sifrujete
aplikacne. Trosku si pomuzete, ale ne moc. Musite to stejne v
aplikaci resit, ze klic je jen pro domluveni spojeni a dalsi
komunikace je s dalsim domluvenym klicem, aby to nebylo
napadnutelne. I v tom procesu overovani i kdyz mate klic to neni
jednoduche, logicky nesmite dopustit predani dat takovym zpusobem,
aby na druhe strane hrubou silou jednoduse poznali co je ok a co
ne. Inspirace neco jako ssh.</p>
