Description

Bit mask (8 bits)

RFU

Integer (bit 0x80)

Zero padding

Integer (bit mask area 0x70)

Number of random bytes which are sent within one proximity check round.

DisableIsoWrapping

Boolean (bit 0x08)

UseExtProxKey

Boolean (bit 0x04)

Use (external) Proximity key given as command parameter.

If the card is already authenticated (VC Selection or Card Authentication), do not activate this option.

DiversifyProxKey

Boolean (bit 0x02)

Key diversification of the proximity key defined in Crypto Memory or SAM will be done according to NXP AN10922.

UseProxKey

Boolean (bit 0x01)

Proximity key is defined in Crypto Memory or SAM.

If the card is already authenticated (Card Authentication), do not activate this option.

Optional field, condition: UseProxKey

ProxKeyIdx

Integer (16 bits)

Crypto Memory Index (SAM or CryptoMemory) of Proximity Check Key

SAM: MSByte: Key version / LSByte: KeyIdx
Crypto Memory: MSByte: Page (0..15) / LSByte: KeyIdx (0x80-0xBF)

Optional field, condition: DiversifyProxKey and UseProxKey

Length of DivData	Integer (8 bits)	Length of DivData in bytes
DivData	Raw data	Key diversification according to NXP AN10922.

Optional field, condition: UseExtProxKey

Length of ProxKey	Integer (8 bits)	Length of ProxKey in bytes
ProxKey	Raw data	Proximity Check Key
