Pokud mají uživatelé trvalé identity, i když se jedná pouze o náhodné číslo, jako je ID relace, existuje riziko, že poskytovatel nebo útočník může sledovat, jak jsou uživatelé připojeni a kolik zpráv odesílají.
|
||
</p>
|
||
<p>
|
||
Tyto informace by pak mohli korelovat se stávajícími veřejnými sociálními sítěmi a určit některé skutečné identity.
|
||
</p>
|
||
<p>
|
||
I v těch nejsoukromějších aplikacích, které používají služby Tor v3, pokud mluvíte se dvěma různými kontakty prostřednictvím stejného profilu, může být prokázáno, že jsou spojeni se stejnou osobou.
|
||
</p>
|
||
<p>
|
||
SimpleX chrání před těmito útoky tím, že nemá žádné ID uživatele ve svém designu. A pokud používáte režim Inkognito, budete mít pro každý kontakt jiné zobrazované jméno, čímž se vyhnete sdílení dat mezi nimi.

Mnoho uživatelů se ptalo: <em>Pokud SimpleX nemá žádné uživatelské identifikátory, jak může vědět, kam doručit zprávy?</em>
|
||
</p>
|
||
<p>
|
||
Pro doručování zpráv používá SimpleX namísto ID uživatelů používaných všemi ostatními platformami dočasné anonymní párové identifikátory front zpráv, oddělené pro každé z vašich připojení - neexistují žádné dlouhodobé identifikátory.
|
||
</p>
|
||
<p>
|
||
Definujete, které servery se mají používat k přijímání zpráv, vašich kontaktů — servery, které používáte k odesílání zpráv. Každá konverzace bude pravděpodobně používat dva různé servery.
|
||
</p>
|
||
<p>
|
||
Tento návrh zabraňuje úniku metadat uživatelů na úrovni aplikace. Chcete-li dále zlepšit soukromí a chránit svou IP adresu, můžete se připojit k serverům pro zasílání zpráv přes Tor.
|
||
</p>
|
||
<p>
|
||
Pouze klientská zařízení ukládají uživatelské profily, kontakty a skupiny; zprávy jsou odesílány s dvouvrstvým end-to-end šifrováním.

Mnoho velkých společností používá informace o tom, s kým jste ve spojení, k odhadu vašich příjmů, prodeji produktů, které ve skutečnosti nepotřebujete, a ke stanovení cen.
|
||
</p>
|
||
<p>
|
||
Internetoví prodejci vědí, že lidé s nižšími příjmy častěji provádějí urgentní nákupy, takže mohou účtovat vyšší ceny nebo odebírat slevy.
|
||
</p>
|
||
<p>
|
||
Některé finanční a pojišťovací společnosti používají sociální grafy k určení úrokových sazeb a pojistného. Často přiměje lidi s nižšími příjmy platit více —, je to známé jako <a href="https://fairbydesign.com/povertypremium/" target="_blank">„prémie za chudobu“</a>.
|
||
</p>
|
||
<p>
|
||
Platforma SimpleX chrání soukromí vašich připojení lépe než jakákoli jiná alternativa a plně zabraňuje tomu, aby byl váš sociální graf dostupný všem společnostem nebo organizacím. I když lidé používají servery poskytované SimpleX Chat, neznáme počet uživatelů ani jejich připojení.

Není to tak dávno, co jsme pozorovali, jak velké volby zmanipulovala <a href="https://en.wikipedia.org/wiki/Facebook–Cambridge_Analytica_data_scandal" target="_blank">renomovaná poradenská společnost</a>, která používala naše sociální grafy ke zkreslení našeho pohledu na skutečný svět a manipulovala s našimi hlasy.
|

|

Chcete-li být objektivní a činit nezávislá rozhodnutí, musíte mít svůj informační prostor pod kontrolou. Je to možné pouze v případě, že používáte soukromou komunikační platformu, která nemá přístup k vašemu sociálnímu grafu.
|
||
</p>
|
||
<p>
|
||
SimpleX je první platforma, která nemá žádné uživatelské identifikátory záměrně, a tímto způsobem chrání váš graf připojení lépe než jakákoli známá alternativa.

Každý by se měl starat o soukromí a bezpečnost své komunikace — neškodné rozhovory vás mohou vystavit nebezpečí, i když nemáte co skrývat.

Jedním z nejvíce šokujících příběhů je zkušenost <a href="https://en.wikipedia.org/wiki/Mohamedou_Ould_Slahi" target="_blank">Mohamedoua Oulda Salahiho</a> popsaná v jeho pamětech a zobrazená v Mauritánském filmu. Byl umístěn do tábora na Guantánamu bez soudu a byl tam 15 let mučen po telefonátu svému příbuznému v Afghánistánu pro podezření z účasti na útocích z 11. září, i když předchozích 10 let žil v Německu.

Obyčejní lidé jsou zatčeni za to, co sdílejí online, dokonce i prostřednictvím svých „anonymních“ účtů, <a href="https://www.dailymail.co.uk/news/article-11282263/Moment-police-swoop-house-devout-catholic-mother-malicious-online-posts.html" target="_blank">i v demokratických zemích</a>.

Nestačí používat end-to-end šifrovaný messenger, všichni bychom měli používat messengery, které chrání soukromí našich osobních sítí — s kým jsme spojeni.

Na rozdíl od jiných platforem pro zasílání zpráv nemá SimpleX <strong> žádné identifikátory přiřazené uživatelům</strong>. Nespoléhá se na telefonní čísla, adresy založené na doméně (jako je e-mail nebo XMPP), uživatelská jména, veřejné klíče nebo dokonce náhodná čísla k identifikaci svých uživatelů —. Nevíme', kolik lidí používá naše servery SimpleX.
|
||
</p>
|
||
<p>
|
||
K doručování zpráv SimpleX používá <a href="https://csrc.nist.gov/glossary/term/Pairwise_Pseudonymous_Identifier">párové anonymní adresy</a> jednosměrných front zpráv, oddělených pro přijaté a odeslané zprávy, obvykle přes různé servery. Používání SimpleX je jako mít <strong> jinou “ vypalovačku” e-mail nebo telefon pro každý kontakt</strong> a žádné potíže s jejich správou.
|
||
</p>
|
||
<p>
|
||
Tento design chrání soukromí toho, s kým komunikujete, a skrývá ho před servery platformy SimpleX a před jakýmikoli pozorovateli. Chcete-li skrýt svou IP adresu před servery, můžete se <strong>připojit k serverům SimpleX přes Tor</strong>.

Protože na platformě SimpleX nemáte žádný identifikátor, nikdo vás nemůže kontaktovat, pokud nesdílíte jednorázovou nebo dočasnou uživatelskou adresu jako QR kód nebo odkaz.

<p>
|

Dokonce i s volitelnou uživatelskou adresou, kterou lze použít k zasílání spamových požadavků na kontakt, ji však můžete změnit nebo úplně odstranit, aniž byste ztratili jakékoli spojení.

SimpleX Chat ukládá všechna uživatelská data pouze na klientských zařízeních pomocí <strong>přenosného šifrovaného databázového formátu</strong>, který lze exportovat a přenést na jakékoli podporované zařízení.
|
||
</p>
|
||
<p>
|
||
End-to-end šifrované zprávy jsou dočasně uchovávány na přenosových serverech SimpleX, dokud nejsou přijaty, poté jsou trvale odstraněny.
|
||
</p>
|
||
<p>
|
||
Na rozdíl od serverů federovaných sítí (e-mail, XMPP nebo Matrix) servery SimpleX neukládají uživatelské účty, pouze předávají zprávy, čímž chrání soukromí obou stran.
|
||
</p>
|
||
<p>
|
||
Mezi odeslaným a přijatým provozem serveru nejsou žádné společné identifikátory ani šifrovaný text — pokud to někdo pozoruje, nemůže snadno určit, kdo s kým komunikuje, i když je TLS kompromitován.

SimpleX můžete <strong>použít se svými vlastními servery</strong> a přesto komunikovat s lidmi, kteří používají námi poskytované předkonfigurované servery.
|
||
</p>
|
||
<p>
|
||
Platforma SimpleX používá <a href="https://github.com/simplex-chat/simplexmq/blob/stable/protocol/overview-tjr.md" target="_blank">otevřený protokol</a> a poskytuje <a href="https://github.com/simplex-chat/simplex-chat/tree/stable/packages/simplex-chat-client/typescript" target="_blank">SDK k vytváření chat botů</a>, což umožňuje implementaci služeb, se kterými mohou uživatelé komunikovat prostřednictvím chatovacích aplikací SimpleX —, Nemůžeme se dočkat, až uvídíme, jaké služby SimpleX dokážete vytvořit.
|

Pokud uvažujete o vývoji pro platformu SimpleX, například chat bota pro uživatele aplikace SimpleX nebo o integraci knihovny SimpleX Chat do vašich mobilních aplikací, <a href="https://simplex.chat/contact#/?v=1&smp=smp%3A%2F%2FPQUV2eL0t7OStZOoAsPEV2QYWt4-xilbakvGUGOItUo%3D%40smp6.simplex.im%2FK1rslx-m5bpXVIdMZg9NLUZ_8JBm8xTt%23MCowBQYDK2VuAyEALDeVe-sG8mRY22LsXlPgiwTNs9dbiLrNuA7f3ZMAJ2w%3D" target="_blank"> kontaktujte pro</a> jakoukoli radu a podporu.

<a href="https://en.wikipedia.org/wiki/Peer-to-peer">P2P</a> protokoly a aplikace pro zasílání zpráv mají různé problémy, které je činí méně spolehlivými než SimpleX, složitějšími na analýzu a zranitelnými vůči několika typům útoků.
|
||
</p>
|
||
<ol style="list-style: auto; padding-left: 1em;">
|
||
<li>
|
||
P2P sítě spoléhají na nějakou variantu <a href="https://en.wikipedia.org/wiki/Distributed_hash_table">DHT</a> pro směrování zpráv. Návrhy DHT musí vyvážit záruku dodávky a latenci. SimpleX má lepší záruku doručení a nižší latenci než P2P, protože zpráva může být redundantně předána přes několik serverů paralelně pomocí serverů vybraných příjemcem. V P2P sítích je zpráva předávána přes uzly <em>O(log N)</em> postupně pomocí uzlů vybraných algoritmem.
|
||
</li>
|
||
<li>
|
||
SimpleX, na rozdíl od většiny P2P sítí, nemá žádné globální uživatelské identifikátory jakéhokoli druhu, dokonce ani dočasné, a používá pouze dočasné párové identifikátory, které poskytují lepší anonymitu a ochranu metadat.
|
||
</li>
|
||
<li>
|
||
P2P neřeší problém <a href="https://en.wikipedia.org/wiki/Man-in-the-middle_attack">MITM útoku</a> a většina existujících implementací nepoužívá out-of-band zprávy pro počáteční výměnu klíčů. SimpleX používá out-of-band zprávy nebo v některých případech již existující zabezpečená a důvěryhodná připojení pro počáteční výměnu klíčů.
|
||
</li>
|
||
<li>
|
||
Implementace P2P mohou být některými poskytovateli internetu blokovány (například <a href="https://en.wikipedia.org/wiki/BitTorrent">BitTorrent</a>). SimpleX je transportně nezávislý - může pracovat přes standardní webové protokoly, např. přes WebSockets.
|
||
</li>
|
||
<li>
|
||
Všechny známé P2P sítě mohou být zranitelné vůči <a href="https://en.wikipedia.org/wiki/Sybil_attack">Sybil útoku</a>, protože každý uzel je zjistitelný a síť funguje jako celek. Známá opatření ke zmírnění tohoto problému vyžadují buď centralizovanou součást, nebo drahé <a href="https://en.wikipedia.org/wiki/Proof_of_work">prokázání práce</a>. Síť SimpleX nemá možnost zjistitelnosti serveru, je fragmentovaná a funguje jako několik izolovaných podsítí, což znemožňuje útoky v celé síti.
|
||
</li>
|
||
<li>
|
||
Sítě P2P mohou být zranitelné vůči útoku <a href="https://www.usenix.org/conference/woot15/workshop-program/presentation/p2p-file-sharing-hell-exploiting-bittorrent">DRDoS</a>, kdy klienti mohou znovu vysílat a zesílit provoz, což vede k odmítnutí služby v celé síti. SimpleX klienti pouze přenášejí provoz ze známého spojení a nemohou být zneužiti útočníkem k zesílení provozu v celé síti.

Blockchains are a subset of <a href="#merkle-directed-acyclic-graph">Merkle directed acyclic graphs</a>.</p><p>In a more narrow sense, particularly in media, blockchain is used to refer specifically to distributed ledger, where each record also includes the hash of the previous record, but the blocks have to be agreed by the participating peers using some <a href="https://en.wikipedia.org/wiki/Consensus_(computer_science)">consensus protocol</a>.</p><p><a href="https://en.wikipedia.org/wiki/Blockchain">Wikipedia</a></p></div><svg class="close-overlay-btn" id="cross" width="16" height="16" viewBox="0 0 13 13" xmlns="http://www.w3.org/2000/svg"><path d="M12.7973 11.5525L7.59762 6.49833L12.7947 1.44675C13.055 1.19371 13.0658 0.771991 12.8188 0.505331C12.5718 0.238674 12.1602 0.227644 11.8999 0.480681L6.65343 5.58028L1.09979 0.182228C0.805 0.002228 0.430001 0.002228 0.135211 0.182228C-0.159579 0.362228 -0.159579 0.697228 0.135211 0.877228L5.68885 6.27528L0.4918 11.3295C0.231501 11.5825 0.220703 12.0042 0.467664 12.2709C0.714625 12.5376 1.12625 12.5486 1.38655 12.2956L6.63302 7.196L12.1867 12.5941C12.4815 12.7741 12.8565 12.7741 13.1513 12.5941C13.4461 12.4141 13.4461 12.0791 13.1513 11.8991L12.7973 11.5525Z"></path></svg></div></div><div id="merkle-directed-acyclic-graph" class="overlay glossary-overlay hidden"><div class="overlay-card"><h1 class="overlay-title">Merkle directed acyclic graph</h1><div class="overlay-content"><p>Also known as Merkle DAG, a data structure based on a general graph structure where node contains the cryptographic hashes of the previous nodes that point to it.

Unlike client-server architecture, all peers in a P2P network both provide and consume the resources. In the context of messaging, P2P architecture usually means that the messages are sent between peers, without user accounts or messages being stored on any servers. Examples are Tox, Briar, Cwtch and many others.</p><p>The advantage is that the participants do not depend on any servers. There are <a href="./SIMPLEX.md#comparison-with-p2p9-messaging-protocols">multiple downsides</a> to that architecture, such as no asynchronous message delivery, the need for network-wide peer addresses, possibility of network-wide attacks, that are usually mitigated only by using a centralized authority.
