Embodiment 1

[0096] Embodiment 1. A system comprising: a computing device including a processor, a memory, and a cryptographic co-processor; and machine-readable instructions stored in the memory, when executed by the When executed by the processor, the machine-readable instructions cause the computing device to at least: receive encrypted code from a service via a network, the encrypted code implementing an encryption algorithm; decrypting the encrypted code; executing the decrypted code by the encryption co-processor to generate a password including information encrypted using the encryption algorithm; and sending the password to the service via the network.

Embodiment 2

[0097] Embodiment 2. The system of embodiment 1, wherein the cryptographic coprocessor conforms to a version of the Trusted Platform Module (TPM) standard.

Embodiment 3

[0098] Embodiment 3. The system of embodiment 1, wherein the cryptographic co-processor is configured to verify the state of the computing device prior to decrypting the encrypted code.

Abstract

Various embodiments are disclosed for executing encrypted code specific for an entity in an encrypted coprocessor. In one embodiment, encrypted code is received from a service via a network, the encrypted code implementing an encryption algorithm. And the encryption coprocessor decrypts the encrypted code. The encryption co-processor executes the decrypted code to generate a password that includes information encrypted using the encryption algorithm. The password is sent to the service via the network.
