Abstract

"GERAçãO DE MENSAGENS DE CHAVE SECRETA". A invenção fornece métodos e sistemas habilitados por computador para a transmissão segura e recebimento e decifração independente de plataforma de mensagens criptografadas. De acordo com a invenção as mensagens são criptografadas por um algoritmo de criptografia simétrico que utiliza uma chave secreta que é, ou está baseada em, uma senha conhecida do recebedor pretendido. Ao recebedor também é enviado um programa de computador o qual quando da inserção da senha correta, utiliza a senha para gerar a chave secreta, ou alternativamente, utiliza a senha como a chave secreta. O programa então utiliza a chave secreta para decifrar a mensagem criptografada. A invenção ainda permite assegurar a integridade e a autenticidade das mensagens enviadas e recebidas. O meio de comunicação sobre o qual as mensagens são enviadas de acordo com a invenção pode ser uma rede de comunicação tal como a Internet e as mensagens podem ser mensagens de correio eletrónico e mensagens MIME. A invenção também permite a entrega segura de declarações e de informações de transações que pertençam a uma conta.
