Abstract

Patente de Invenção "PROCESSO DE IMPLEMENTAçãO EM HARDWARE DO ALGORìTIMO CRIPTOGRáFICO IDEA - HIPCRYPTO". O HIPCrypto é a implementação em hardware do algoritmo de chave privada considerado mais seguro na atualidade, o algoritmo IDEA (International Data Encriyption Algorithm), através da exploração das técnicas de paralelismo espacial e temporal, de forma a atender as velocidades de processamento requeridas pelas redes do tipo ATM.
