Abstract

Uma instrução para executar cifragem e autenticação é executada. A execução inclui a cifragem de um conjunto de dados fornecidos pela instrução para obter dados cifrados e colocar os dados cifrados em um local designado. Ela inclui ainda a autenticação de um conjunto de dados adicional fornecido pela instrução, em que a autenticação gera pelo menos uma parte de uma etiqueta de autenticação de mensagens. Pelo menos uma parte da etiqueta de autenticação de mensagens é armazenada em um local.
