This section describes the format of the TR-31 key block header and the header values supported by CCA. It also describes the TR-31 optional blocks that can be used by CCA. The use of TR-31 key blocks are described in Introduction to TR-31 symmetric key management. See ANSI X9.143-...
TR31是一种安全传入密钥的方法。TR31密钥块的构建，然后导入到终端，终端利用已经导入的KBPK进行TR31密钥块的解密，解密出IPEK和KSN导入密钥容器。KBPK密钥只用于保护以及构建TR-31密钥块(即确保KBPK专钥专用)TR31算法分析 1、构建key block header 密钥块的头是由16个字节的字符串组成“B0080P0TE00E0000”，
Key Status (one required). NO-KEYSpecifies to build a TR-31 key block without a key value. This creates a key block header (For example, a skeleton key token) that can be populated using CSNBKPI2 or used in key derivation services such as CSNBEDH, CSNBUKD, and others. ...
