Embodiment Construction

[0020] The gist of the present invention is to overcome the deficiencies of the prior art and provide a software online upgrade method, which establishes an associated verification and encryption mechanism at both ends of the network server and the product software system, so as to correctly identify the integrity of the software and prevent Wrong or tampered software is upgraded to the product, so that the product side can safely upgrade the software.

[0021] This software online upgrade method uses the asymmetry of the RSA encryption algorithm to encrypt the upgrade software to generate a pair of keys, that is, a public key and a private key. The public key is placed on the network server side, and the private key is placed in the software system of the product. , the public key is used for encryption, and the private key is used for decryption when the product is upgraded. The RSA algorithm is based on a very simple number theory fact. It multiplies two prime numbers and m...

Abstract

The invention discloses a method for upgrading software on line. The method comprises the following steps of: encrypting software to be upgraded by using asymmetry of a radio supervisory adapter (RSA) encryption algorithm to generate a public key and a private key which form a pair; and placing the public key at a network server end and the private key in a software system of a product, wherein the public key is used for encryption and the private key is used for decryption. Two prime numbers are multiplied by an RSA, and the product is publically used as an encryption key and is resolved into factors during decryption; but the two prime numbers can be more easily multiplied and the product can be extremely difficultly dissolved into the factors. The encryption and the decryption at the network server end and a product end are set by an RSA data encryption algorithm and a secure hash algorithm (SHA) 1 data digest algorithm respectively; the software can be downloaded and upgraded after settings are compared to be consistent; associated verification and encryption mechanisms are established at the two ends, namely the network server end and the product software system end; thus the integrity of the software is correctly identified, the wrong or tampered software is prevented from being upgraded into the product, and the software at the product end is securely upgraded.

Description

technical field [0001] The invention relates to a software upgrading method, in particular to an online safe and confidential software upgrading method. Background technique: [0002] At present, with the popularization of network applications and the increase of software complexity, more and more products provide online software upgrade functions, such as mobile phones, Internet TVs, set-top boxes, and players. The usual way is: the software system of the product connects to the network server, downloads the software and completes the upgrade. This method is simple and practical, but with the increasingly complex network environment, the following hidden dangers need to be considered: first, some data errors may occur when the software is transmitted in the network; second, malicious attacks by hackers, Tampering with the software files on the network server; Third, the routing is artificially intervened, so that the software system of the product is linked to the wrong se...
