Abstract

Controladora para transferência de dados com múltiplos registros para suporte à operações cifradas. Um sistema de processamento de dados que cifra e transfere os dados, de uma primeira unidade de memória para uma segunda unidade de memória, podendo ser estas, por exemplo, entre uma SMA SRAM (SMA: "Arquitetura de Memória Compartilhada", SRAM: "Memória de Acesso Aleatório Estático") e uma DDR SDRAM (DDR: "Taxa de Transferência Dobrada", SDRAM: "Memória Síncrona de Acesso Aleatório Dinâmico"). O sistema inclui um mecanismo para a cifragem e uma controladora para a transferência de dados. A controladora para a transferência de dados inclui, ao menos, um registro que possui um campo que indique se os dados que devem ser transmitidos devam, ou não, serem criptografados. Caso esse campo especifique que a transferência de dados deva ser cifrada, o campo então também especificará qual é o tipo de cifragem a ser utilizado, tal como a "Norma para Algoritmo de Confidencialidade f8" da "Parceria de Projeto de Terceira Geração (3GPP)" ou o "Algoritmo de Integridade de Criptografia f9".
