    • The invention is an apparatus and method for validating that key management functions requested for a cryptographic key by the program have been authorized by the originator of the key. The invention includes a cryptographic facility characterized by a secure boundary through which passes an input path for receiving the cryptographic service requests, cryptographic keys and their associated control vectors, and an output path for providing responses thereto. There can be included within the boundary a cryptographic instruction storage coupled to the input path, a control vector checking unit and a cryptographic processing unit coupled to the instruction storage, and a master key storage coupled to the processing means, for providing a secure location for executing key management functions in response to the received service requests. The cryptographic instruction storage receives over the input path a cryptographic service request for performing a key management function on a cryptographic key. The control vector checking unit has an input coupled to the input path for receiving a control vector associated with the cryptographic key and an input connected to the cryptographic instruction storage, for receiving control signals to initiate checking that the control vector authorizes the key management function which is requested by the cryptographic service request. The control vector checking unit has an authorization output connected to an input of the cryptographic processing means, for signalling that the key management function is authorized, the receipt of which by the cryptographic processing unit initiates the performance of the requested key management function with the cryptographic key. The invention enables the flexible control of many cryptographic key management functions in the generation, distribution and use of cryptographic keys, while maintaining a high security standard.

    • Cryptographic PIN processing is achieved in an improved manner by associating control vectors with the PIN generating (verification) keys and PIN encrypting keys which provide authorization for the uses of the keys intended by the originator of the keys. The originator may be the local cryptographic facility (CF) and a utility program under the control of a security administrator, or the originator may be another network node which uses the key management methods described in the above-referenced copending patent applications to distribute said keys.Among the uses specified by the control vector are limitations on the authority to use the associated key with certain PIN processing instructions, such as PIN generation, verification, translation and PIN block creation. Furthermore, the control vector may limit the authority of certain instructions to process clear PIN inputs (such as in PIN verification). The control vector may contain information identifying and, possibly restricting, PIN processing to a particular PIN format or particular processing algorithm.The control vector implementation provides a flexible method for coupling format, usage, and processing authorization to keys. The system administrator can exercise flexibility in changing the implementation of his security policy by selecting appropriate control vectors in accordance with the invention. Furthermore, a method is provided for the security administrator to restrict certain PIN format translations.
    • 通过将控制向量与PIN生成(验证)密钥和PIN加密密钥相关联来实现密码PIN处理,该密码提供对使用密钥发起者所期望的密钥的授权。 发起者可以是本地加密设施(CF)和在安全管理员的控制下的实用程序,或者发起者可以是使用上述参考的未决专利申请中描述的密钥管理方法的另一个网络节点来分发所述密钥 。 由控制向量指定的用途之一是对使用相关密钥与某些PIN处理指令(例如PIN生成,验证,翻译和PIN块创建)的权限的限制。 此外,控制向量可以限制某些指令的权限来处理明确的PIN输入(例如在PIN验证中)。 控制向量可以包含识别并且可能限制对特定PIN格式或特定处理算法的PIN处理的信息。 控制向量实现提供了一种用于将格式,使用和处理权限耦合到密钥的灵活方法。 系统管理员可以通过根据本发明选择适当的控制向量来灵活地改变其安全策略的实现。 此外,提供了一种用于安全管理员限制某些PIN格式转换的方法。

    • A cryptographic facility implements a multiple key part import procedure. The installation manager can verify that a key part has been correctly entered and has not been compromised. The security requirement for the procedure is that no single party can subvert the system security by misusing the procedure. This is accomplished by the use of a control-vector-dependent verification pattern to indicate that each key part has been accepted by using the proper control vector and the use of different key switch positions to specify whether the key part is a master key part or an operational key part and whether the key part is a first part or a subsequent key part. The apparatus provides an automatic reset of the key part register at the completion of each key-entry instruction so that each key part can be imported only once. This prevents the same key part from being imported twice as different key part types. The apparatus also prevents a key part from being combined with itself to create a known key. The procedure is fail-safe so that the program cannot steal a key part from a previously failed procedure.
    • 密码工具实现了多重关键部分导入过程。 安装管理员可以验证关键部件是否已正确输入,并且未被泄露。 程序的安全要求是,没有一方可以通过滥用程序颠覆系统安全。 这是通过使用控制向量相关的验证模式来实现的,以通过使用适当的控制向量来指示每个关键部分已被接受,并且使用不同的键开关位置来指定关键部分是主键部分还是主键部分 操作键部分以及关键部分是第一部分还是随后的关键部分。 该装置在完成每个键入指令时提供关键部分寄存器的自动复位,使得每个键部分只能被导入一次。 这样可以防止相同的关键部分作为不同的关键部件类型被导入两次。 该装置还防止关键部分与其自身组合以创建已知密钥。 该过程是故障安全的,以便程序不能从以前失败的过程中窃取关键部分。
