Abstract

MéTODO DE VERIFICAçãO DE ASSINATURA OU DE AUTENTICAçãO. A invenção diz respeito a um método para verificar uma assinatura ou uma autenticação entre um autenticador e um verificador baseado num algoritmo de cálculo criptográfico assimétrico. O autenticador calcula (1) ao menos um valor de pré-validação q, o qual é o quociente de dois valores criptográficos a, b pelo módulo público n, e transmite para o verificador este valor q. O verificador calcula (3) os produtos a*b e q*n e a diferença a*b-q*n para executar ao menos uma redução modular sem uma operação de divisão. A invenção aplica-se à verificação de assinatura ou autenticação entre um microcomputador autenticador e um cartão de microprocessador verificador.
