Options
- ASingle sign-on
- BIdentity propagation
- CRemote attestation
- DSecure code review
Explanation
Remote attestation is a mechanism that allows a device to cryptographically prove to a remote party (or itself) that its software and configuration have not been altered. When Ann's software is installed on a mobile device, remote attestation allows the device to verify the software's integrity by comparing cryptographic measurements (hashes) of the installed code against known-good reference values. If the software has been modified, the attestation check fails and the software is prevented from running. Single sign-on (A) addresses authentication, not code integrity. Identity propagation (B) is about passing identity context across systems. Secure code review (D) is a development-time practice to find vulnerabilities, not a runtime mechanism to block tampered copies from executing on devices.
