Abstract
A method and system for securely executing software or securely loading data generates a secret value at a destination device based on a value transmitted to the destination device, which is algorithmically combined with a secure value stored at the destination device. The destination device, such as a cell phone, remotely accesses an entity or otherwise receives the software or data, where the software or data is encrypted or digitally signed based on the secret value. The cell phone then selectively employs the software or data.
