Abstract
A method, an update agent and an off-card entity are provided for implementing an authentication scheme for providing a software image to a secure element. An installation package includes a package binding function for linking the installation package to the secure element, a manifest, a manifest signature generated using a block-cipher algorithm, and a software image is received at an update agent within the secure element. The update agent implements an authentication and integrity scheme by verifying various signatures contained within the installation package and installing the software image in case of successful authentication and integrity verification.
