Abstract

"PROJETO DE CHAVES DE CóDIGO DE CORRENTE COM MEMóRIAS TEMPORáRIAS GIRATóRIAS". Técnicas são descobertas para limitar correlações de curta duração associadas com saídas de geradores de corrente-chave da chave de código de corrente. Valores de saída de um gerador são emparelhados tal como as saídas emparelhadas são suficientemente separadas para serem consideradas independentes. Em uma implementação descrita, um método inclui armazenar seq³encialmente uma pluralidade de resultados fornecidos por uma regra de saída de chave de código de corrente em uma primeira, segunda e terceira unidades de armazenamento. Uma função de emparelhamento emparelha valores individuais da primeira e terceira unidades de armazenamento que são pelo menos um valor limite separado. Mediante o alcance do valor limite dos resultados da regra de saída, o conteúdo das primeira, segunda e terceira unidades de armazenamento é rotacionado serialmente.
