Abstract
Official abstract text for this publication.
A secure software update provides an update utility with an update definition, a private encryption key and a public signature key to a target device. A software update package is prepared on portable media that includes an executable update program, a checksum for the program that is encrypted with a symmetrical key, an encrypted symmetrical key that is encrypted with a public encryption key and a digital signature prepared with a private signature key. The update process authenticates the digital signature, decrypts the symmetrical key using the private encryption key, and decrypts the checksum using the symmetrical key. A new checksum is generated for the executable update program and compared to the decrypted checksum. If inconsistencies are detected during the update process, the process is terminated. Otherwise, the software update can be installed with a relatively high degree of assurance against corruption, viruses and third party interference.
First claim
Opening claim text (preview).
What is claimed is: 1. A system for implementing a software update on a target device, comprising: a target device having a processor coupled to a storage memory and being operable to retrieve and execute instructions stored in the storage memory to implement a checksum algorithm and an update utility, the update utility being operative to access the storage memory to perform a software update verification; wherein the storage memory stores a first encryption key from a first pair…
