Abstract

Se describe una aplicacion en un dispositivo de computo para escribir datos a un medio de almacenamiento asociado con el mismo. Los datos que van a ser escritos a un area de almacenamiento, y el area de almacenamiento seguro tiene un area de almacenamiento de valor asociada con la misma. La aplicacion genera un proposito particular y emplea una clave de sesion compartida (KS) para codificar cripticamente el proposito particular para dar como resultado (KS(proposito particular)). El medio de almacenamiento recibe al mismo y descodifica cripticamente con (KS) para dar como resultado el proposito particular, ubica el area de almacenamiento de valor asociada con el area de almacenamiento seguro, y almacena dicho proposito particular en el area de almacenamiento de valor localizada. La aplicacion emplea el proposito particular para generar una clave (KH), codifica cripticamente los datos con (KH) para dar como resultado (KH(datos)), y los envia al medio de almacenamiento para almacenarse en el area de almacenamiento seguro. De esta manera, (KH(datos)) estan asociados con el proposito particular en el area de almacenamiento de valor.
