TH29936A - Methodology for the provision of secure communication between two devices and their application. - Google Patents

Abstract

DC60 (25/07/57) in a methodology for the provision of secure communication between two devices. The first device will generate a random key (Ci) and this key will be transferred to the second device in the first message. That has been encrypted with a public key. The second device decrypts the message. One that is encrypted using a corresponding cipher key in order to obtain a random key (Ci), and this random key is then used to encrypt and decrypt all transmissions during Both devices are built in decoders for paid TV systems that include a powerful access module. Conditions and smart cards This methodology will be applied in order to provide efficient communication. Secure between access control modules and smart cards and / or between decoders and modules Conditional access In a methodology for the provision of secure communication between two devices. The first device will generate a random key (Ci) and will transfer this key to the second device in the message. One that is encrypted using a public key. The second device decrypts the news. The first substance is encrypted by means of a corresponding cipher key to obtain a random key (Ci), and this random key is then used in order to enter and decrypt it. Of all submissions Between the two devices A built-in decoder for paid TV systems that includes a module Conditional access and wise cards This methodology will be applied in order to make arrangements. Communicate secure communication between the access control module and the smart card and / or Between the decoder and the conditional access module

1. Methodology for providing a secure communication between two devices where one device generates a random key (Ci) and transfers that key to the The second device in the first message is encrypted with a public key. Where the second device It decrypts the first message that is encrypted by means of a cipher key. Corresponding in order to obtain such a random key (Ci) where such random key is used. In order to encrypt and decrypt transmission between all tagged devices:
