Abstract

TéCNICAS PAPA REFORçAR CRIPTOGRAPIA DE ENCHZMENTO DE VEZ úNICA Equipamentos, métodos e meios legíveis por computador para reforçar um sistema de criptografia de enchimento de vez única. Uma modalidade de método da presente invenção compreende as etapas de criptografar texto simples (1), com uma chave OTP (2) em uma operação de XOR para produzir texto cifrado (3); e ofuscar o texto cifrado (3) com uma AutoKey (4) em uma operação de XOR para produzir um texto cifrado por AutoKey (5), em que a AutoKey (4) é uma chave reutilizável.
