Embodiments of a security architecture for securely storing applications, such as Near Field Communication (NFC) applications, in host memory of a mobile device are provided. The mobile device includes a host application processor, a non-volatile memory, a NFC controller, and an embedded Secure Element (eSE). The eSE is configured to encrypt code and state data associated with a NFC application; store the code and the state data, after having been encrypted, in the non-volatile memory as a binary large object (blob); load the blob from the non-volatile memory in response to an action performed by the host application processor or the NFC controller; decrypt and authenticate the code and the state data; and execute the code to exchange data with a contactless communication device via the NFC controller. The non-volatile memory is external to the eSE. |
