ChipAuthenticationHandler

internal final class ChipAuthenticationHandler

ChipAuthenticationHandler is responsible for performing chip authentication to verify the authenticity of the chip.

Chip Authentication prevents copying the SOD and proves that it has been read from the authentic contactless IC and that it has not been substituted.

The protocol provides implicit authentication of both the eMRTD chip itself and the stored data by performing Secure Messaging using the new session keys.
