Problems solved by technology

Therefore, eSEs with integrated non-volatile memory are typically implemented in older, less ideal processes
For example, prior art eSEs with non-volatile memory can be fabricated in a 90nm process, as opposed to being fabricated in the available 40nm process, due to scalability issues associated with integrated non-volatile memory

Abstract

The invention discloses a security architecture for using host memory in the design of a secure element, wherein 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.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Patent Application 61 / 486,625, filed May 16, 2011, and US Patent Application 13 / 173,931, filed June 30, 2011, the entire contents of which are hereby incorporated by reference. technical field [0003] The present application relates generally to security architectures and, more particularly, to security for near field communication applications. Background technique [0004] Near Field Communication (NFC) is a wireless communication technology that allows data to be exchanged between two devices separated by up to ten centimeters. In the near future, NFC-enabled mobile devices are expected to be ubiquitous. NFC-enabled mobile devices can be used as both contactless cards and card readers to provide payment, Capabilities for royalty, ticketing, and access control applications, just to name a few. Generally, there is no need for the owner of an NFC-enabled mobile devi...
