CCID协议全称为"Card Contact Interface for Integrated Circuit (s) Cards", 是一种用于智能卡在USB设备中的通信标准，特别是在Windows 7及更高版本系统中实现无驱动程序支持。该规范主要关注智能卡与USB接口设备之间的交互，确保数据安全和兼容性。 USB Device Class: Smart Card CCID Specification for Integrated Circuit(s) Cards Interface Devices 的修订版本1.1是在2005年4月22日发布的，这表明它已经经历了时间的考验，适应了当时的硬件和技术需求。CCID 1.1版本的目标是提供一种标准化的方式来管理和控制智能卡，使得这些设备能够无缝地接入各种USB设备环境中，如自动取款机（ATM）、移动支付终端、身份验证设备等。在CCID协议中，强调了知识产权声明，指出该规范仅作为"按现状"提供，没有任何形式的保证，包括但不限于商品质量保证、特定用途适用性或因提议、规格或样品导致的任何其他保证。此外，它明确表示，许可仅限于内部使用，没有授予或暗示关于其他知识产权的任何额外权利。作者对基于本规范的实现可能侵犯的专利权或专有权益不承担任何责任，并且并不保证这些实现不会侵犯此类权利。参与该规范制定的贡献者包括Bob Nathan来自NCR公司和Stephen Chas，他们共同确保了协议的技术准确性和实用性。对于开发者来说，理解并遵循CCID协议至关重要，因为它规定了如何设计和制造能与主流操作系统如Windows兼容的智能卡读卡器，同时还要考虑兼容不同类型的智能卡，如金融卡、身份证件认证卡等。此外，为了满足现代网络安全要求，CCID协议也涉及到了数据加密和安全传输等方面，这对于保护用户的隐私和个人信息安全至关重要。 CCID协议是智能卡技术与USB接口融合的关键组成部分，它为智能卡在数字生活中的广泛应用提供了必要的标准框架，使得设备间的交互更加便捷且可靠。在实施时，开发者需要严格遵守协议规定，以确保产品的合规性和用户体验。

4 Standard USB Descriptors

4.1 Device

It is a standard device descriptor as per Chapter 9, “USB Device Framework,” in the

Universal Serial Bus Specification.

It does not contain class-specific information.

4.2 Configuration

DWG Smart-Card Integrated Circuit(s) Card Interface Devices

Offset Field Size Value Description

18 bNumClockSupported 1 The number of clock frequencies that are supported by

the CCID. If the value is 00h, the supported clock

frequencies are assumed to be the default clock

frequency defined by dwDefaultClock and the maximum

clock frequency defined by dwMaximumClock.

The reader must implement the command

PC_to_RDR_SetDataRateAndClockFrequency if more

than one clock frequency is supported.

19 dwDataRate 4 Default ICC I/O data rate in bps. This is an integer value

Example: 9600 bps is encoded as the integer value

9600. (00002580h)

23 dwMaxDataRate 4 Maximum supported ICC I/O data rate in bps

Example: 115.2Kbps is encoded as the integer value

115200. (0001C200h)

27 bNumDataRatesSupported 1 The number of data rates that are supported by the CCID.

If the value is 00h, all data rates between the default data

rate dwDataRate and the maximum data rate

dwMaxDataRate are supported. Those values comply

with § 1.2 and with all clock frequencies supported by the

reader. See offset 18 and

GET_CLOCK_FREQUENCIES § 5.3.2.

28 dwMaxIFSD 4 • Indicates the maximum IFSD supported by CCID for

protocol T=1.

32 dwSynchProtocols 4 RRRR

PPPP

00000000h

• RRRR-Upper Word- is RFU = 0000h

• PPPP-Lower Word- encodes the supported protocol

types. A ‘1’ in a given bit position indicates support

for the associated protocol.

0001h indicates support for the 2-wire protocol

0002h indicates support for the 3-wire protocol

0004h indicates support for the I2C protocol

All other values are outside of this specification, and

must be handled by vendor-supplied drivers.

36 dwMechanical 4 00000000h,

00000008h

The value is a bitwise OR operation performed on the

following values:

• 00000000h No special characteristics

• 00000001h Card accept mechanism

• 00000002h Card ejection mechanism

• 00000004h Card capture mechanism

• 00000008h Card lock/unlock mechanism

This release of the specification does not support devices with the 2-wire, 3-wire, and

I2C protocol so PPPP = 0000h. This field is intended to be forward compatible with the

PCSC specification.

These mechanisms of the dwMechanical parameter have been included for

completeness; however, these functions of motorized CCIDs are not covered by this

release of the specification. A future release may attempt to standardize the interface to

these mechanical functions.

DWG Smart-Card Integrated Circuit(s) Card Interface Devices

Offset Field Size Value Description

40 dwFeatures 4 xxxxxxxxh This value indicates what intelligent features the CCID has. The value

is a bitwise OR operation performed on the following values:

• 00000000h No special characteristics

• 00000002h Automatic parameter configuration based on ATR

data

• 00000004h Automatic activation of ICC on inserting

• 00000008h Automatic ICC voltage selection

• 00000010h Automatic ICC clock frequency change

according to active parameters provided by the Host or self

determined

• 00000020h

Automatic baud rate change according to active

parameters provided by the Host or self determined

• 00000040h

Automatic parameters negotiation made by the

CCID (use of warm or cold resets or PPS according to a

manufacturer proprietary algorithm to select the communication

parameters with the ICC)

• 00000080h

Automatic PPS made by the CCID according to the

active parameters

• 00000100h CCID can set ICC in clock stop mode

• 00000200h NAD value other than 00 accepted (T=1 protocol in

use)

• 00000400h Automatic IFSD exchange as first exchange (T=1

protocol in use)

Only one of the following values may be present to select a level of

exhange:

• 00010000h TPDU level exchanges with CCID

• 00020000h Short APDU level exchange with CCID

• 00040000h Short and Extended APDU level exchange with CCID

• If none of those values is indicated the level of exchange is

character.

Only one of the values 00000040h and 00000080h may be present.

When value 00000040h is present the host shall not try to change the

FI, DI, and protocol currently selected.

When an APDU level for exchanges is selected, one of the values

00000040h or 00000080h must be present, as well as the value

00000002h.

To support selective suspend:

• 00100000h USB Wake up signaling supported on card insertion

and removal

When bit 20

, as shown above, is set bit D5 in bmAttributes of the

Standard Configuration Descriptor must be set to 1.

When a CCID doesn't declare the value 00000010h the frequency must be made via

the manufacturer proprietary PC_to_RDR_Escape command, same thing for the baud

rate when the value 00000020h is not declared.

When a CCID using TPDU exchange level declares neither of the values 00000040h,

or 00000080h, the PPS exchange must be made using a TPDU for PPS exchange.

Offset Field Size Value Description

44 dwMaxCCIDMessageLength 4 For extended APDU level the value shall be between 261 + 10

(header) and 65544 +10, otherwise the minimum value is the

wMaxPacketSize of the Bulk-OUT endpoint.

48 bClassGetResponse 1 Significant only for CCID that offers an APDU level for

exchanges.

Indicates the default class value used by the CCID when it

sends a Get Response command to perform the transportation

of an APDU by T=0 protocol.

Value FFh indicates that the CCID echoes the class of the

APDU.

49 bClassEnvelope 1 Significant only for CCID that offers an extended APDU level

for exchanges.

Indicates the default class value used by the CCID when it

sends an Envelope command to perform the transportation of

an extended APDU by T=0 protocol.

Value FFh indicates that the CCID echoes the class of the

APDU.

50 wLcdLayout 2 XXYYh Number of lines and characters for the LCD display used to

send messages for PIN entry.

XX: number of lines

YY: number of characters per line.

XXYY=0000h no LCD.

52 bPINSupport 1 00h-03h This value indicates what PIN support features the CCID has.

The value is a bitwise OR operation performed on the following

values:

01h PIN Verification supported

02h PIN Modification supported

53 bMaxCCIDBusySlots 1 01h-FFh Maximum number

of slots which can be simultaneously busy.

5.2 CCID Endpoints

A CCID shall support a minimum of two endpoints in addition to the default (control)

endpoint: one bulk-out and one bulk-in. A CCID that reports ICC insertion or removal

events must also support an interrupt endpoint.

Table 5.2-1 Configuration of endpoints for a CCID

Endpoint Direction Option Definition

Bulk OUT OUT Mandatory CCID Command pipe

Bulk IN IN Mandatory CCID Response pipe

Interrupt IN Optional CCID Event Notification pipe

If the CCID does not support queuing, it reports bMaxCCIDBusySlots equal to 01h;

which means that the CCID will treat all commands synchronously.
