Um grupo de pesquisadores, desenvolvedores e cript\u00f3grafos alem\u00e3es publicou a primeira edi\u00e7\u00e3o do projeto Rosenpass, que desenvolve um VPN e um mecanismo de troca de chaves resistentes a ataques de computadores qu\u00e2nticos. O transporte utiliza o VPN WireGuard com algoritmos de criptografia e chaves padr\u00e3o, enquanto o Rosenpass o complementa com meios de troca de chaves, protegidos contra ataques em computadores qu\u00e2nticos (ou seja, o Rosenpass oferece prote\u00e7\u00e3o adicional para a troca de chaves sem alterar os algoritmos e m\u00e9todos de criptografia do WireGuard). O Rosenpass tamb\u00e9m pode ser utilizado separadamente do WireGuard como uma ferramenta universal de troca de chaves, adequada para proteger outros protocolos contra ataques de computadores qu\u00e2nticos. <\/p>\n

O c\u00f3digo da ferramenta \u00e9 escrito na linguagem Rust e \u00e9 distribu\u00eddo sob as licen\u00e7as MIT e Apache 2.0. Os algoritmos e primitivas criptogr\u00e1ficas s\u00e3o retirados das bibliotecas liboqs e libsodium, escritas em linguagem C. A base de c\u00f3digo publicada \u00e9 posicionada como uma implementa\u00e7\u00e3o de refer\u00eancia \u2014 com base nas especifica\u00e7\u00f5es fornecidas, podem ser desenvolvidas alternativas da ferramenta usando outras linguagens de programa\u00e7\u00e3o. Atualmente, est\u00e1 em andamento um trabalho de verifica\u00e7\u00e3o formal do protocolo, dos algoritmos criptogr\u00e1ficos e da implementa\u00e7\u00e3o para fornecer uma prova matem\u00e1tica de confiabilidade. Atualmente, foi realizada uma an\u00e1lise simb\u00f3lica do protocolo e de sua implementa\u00e7\u00e3o b\u00e1sica na linguagem Rust com o aux\u00edlio do ProVerif. <\/p>\n

O protocolo Rosenpass \u00e9 baseado no mecanismo de troca de chaves autenticadas p\u00f3s-qu\u00e2nticas PQWG (Post-quantum WireGuard), constru\u00eddo com o uso do sistema criptogr\u00e1fico McEliece, que \u00e9 resistente a ataques em computadores qu\u00e2nticos. A chave gerada no Rosenpass \u00e9 utilizada na forma de uma chave sim\u00e9trica compartilhada (PSK, pre-shared key) do WireGuard, implementando uma camada adicional para prote\u00e7\u00e3o h\u00edbrida VPN<\/a>-da conex\u00e3o. <\/p>\n

O Rosenpass fornece um processo em segundo plano independente, utilizado para gerar chaves pr\u00e9-definidas do WireGuard e proteger a troca de chaves durante o processo de negocia\u00e7\u00e3o da conex\u00e3o (handshake) utilizando m\u00e9todos de criptografia p\u00f3s-qu\u00e2ntica. Assim como no WireGuard, as chaves sim\u00e9tricas no Rosenpass s\u00e3o atualizadas a cada dois minutos. Para proteger a conex\u00e3o, s\u00e3o utilizadas chaves compartilhadas (em cada lado, um par de chaves p\u00fablicas e privadas \u00e9 gerado, e os participantes trocam suas chaves p\u00fablicas).
