HDCP格式遭遇破解,主密钥被公布

高带宽数码内容保护HDCPHigh-Bandwidth Digital Content Protection),是由英特尔公司所发展,用以确保数字化的图像声音数据在通过DVIHDMI接口传送时不至于遭到非法拷贝。HDCP的规格受到多项专利权保护,任何人欲实现HDCP必须申请授权

HDCP的授权管理是由英特尔子公司数字内容保护公司”(Digital Content Protection, LLC)负责。除了交付授权金之外,生产HDCP兼容设备的厂商必须限制其产品功能,例如高清画面(分辨率超过480p者)在通过产品上不支持HDCP的接口播放时必须支持碟片需求将分辨率降至480p,而DVD声讯在通过不支持HDCP的接口时必须被强制降到DAT等级的模拟输出。所有支持HDCP的影音播放设备都不得支持数字数据直接拷贝功能,并且必须“将其产品设计到足以打消大多数破解者的念头”。

基本来说,欲播放有HDCP保护的影音内容如HD DVDBlu-ray DiscPlayStation 3游戏(通过HDMI输出时),信号来源(播放机电脑显卡)和显示器双方都必须自带HDCP密钥芯片才能正常播放。若系统任何一者不配备此密匙芯片,图像质素有可能降低,甚至不能播放图像。现时某些显卡已自带HDCP芯片,有限度支持HDMI输出。

 

HDCP MASTER KEY (MIRROR THIS TEXT!)

This is a forty times forty element matrix of fifty-six bit hexadecimal numbers. To generate a source key, take a forty-bit number that (in binary) consists of twenty ones and twenty zeroes; this is the source KSV. Add together those twenty rows of the matrix that correspond to the ones in the KSV (with the lowest bit in the KSV corresponding to the first row), taking all elements modulo two to the power of fifty-six; this is the source private key. To generate a sink key, do the same, but with the transposed matrix.
