Abstract
Systems and methods for secure transaction authorization are provided. An emulator is instantiated on a host device and configured to emulate an integrated circuit having a different instruction set than an integrated circuit of the host device, and a guest operating system executing on the emulated integrated circuit is configured to communicate with a host operating system of the host device through an emulated network interface of the emulator. Under control of one or more guest operating system processes executing on the emulated integrated circuit, a request is received over a first secure communication channel from an application executing on the host operating system to authorize a transaction. An authorization result is received from a remote system over a second secure communication channel, and a response is sent to the application over the first secure communication channel indicating the authorization result.
