Abstract
An integrated circuitis provided, which is configured for authentication itself and technical information concerning the integrated circuit or its installed software to an external computing device. The integrated circuitcomprises a signerfor producing a signature over the information and a challenge using a cryptographic signing key, and a communication modulefor providing the information and the signature to the computing device. In response to receiving the information and the authentication, the computing devicemay install new application code on the integrated circuit. After the installation, the integrated circuit may authenticate information concerning the new application code to other computing devices. The integrated circuit is advantageously a multiple application smart card, since it allows application providers to obtain trust in the multiple application smart card without having a relationship with its manufacturer.
