All Implemented Interfaces:

Serializable, LDSElement

public class ChipAuthenticationPublicKeyInfo
extends SecurityInfo

A concrete SecurityInfo structure that stores chip authentication public key info, see EAC TR 03110 1.11 specification. This data structure provides a Chip Authentication Public Key of the MRTD chip.

• The object identifier protocol SHALL identify the type of the public key (i.e. DH or ECDH).
• The sequence chipAuthenticationPublicKey SHALL contain the public key in encoded form.
• The integer keyId MAY be used to indicate the local key identifier. It MUST be used if the MRTD chip provides multiple public keys for Chip Authentication.

Version:

$Revision: 1613 $ FIXME: interface dependency on BC classes? FIXME: maybe clean up some of these constructors...
