Abstract

método implementado por processador voltado para assegurar a integridade do software. a presente invenção proporciona com uma solução junto ao problema de assegurar-se quanto a integridade de programas de software por meio de criptografia de parte ou da totalidade pertinente a cada instrução de um programa fazendo emprego de um caractere baseado parcialmente ou totalmente em uma instrução anterior ou na pluralidade de instruções anteriores, resultando, desse modo, em um diferenciado caractere de criptografia por instrução. a invenção encontra aplicação junto à programas de software cujas estruturas não se apresentem necessariamente sob o formato naturalmente ramificado, encontrando ainda aplicação quando os programas incluem a presença de enlaces, saltos, chamadas ou quebras, etc. a invenção fornece condições ainda a que ocorra a sinalização de excepcionalidades quando da efetuação errônea da decodificação de uma instrução criptografada. não existe nenhuma necessidade para que a primeira instrução seja aberta, uma vez que o caracter de instrução pode vir a ser inicializado adequadamente conforme se faça necessáriio. a invenção pode ser projetada em software ou inteiramente em hardware, eliminando qualquer possibilidade quanto a terceiros de virem a interceptar uma instrução decodificada ou um caractere decodificado.processor-implemented method to ensure software integrity. The present invention provides a solution to the problem of ensuring the integrity of software programs by encrypting part or all pertinent to each instruction of a program employing a character based partially or wholly on a previous instruction. or in the plurality of previous statements, thereby resulting in a differentiated encryption character per instruction. The invention finds application with software programs whose structures are not necessarily in a naturally branched format, and finds application when programs include links, hops, calls or breaks, etc. The invention further provides conditions for exceptionality signaling to occur when erroneously decoding an encrypted instruction. There is no need for the first instruction to be opened, as the instruction character can be initialized properly as needed. The invention may be designed in software or entirely in hardware, eliminating any possibility for third parties to intercept a decoded instruction or a decoded character.
