摘要：
A device includes a key store memory, a rule set memory, a plurality of cryptographic clients, and a key store arbitration module. The key store memory stores a plurality of cryptographic keys and the rule set memory stores a set of rules for accessing the cryptographic keys. A cryptographic client is operable to issue a request to access a cryptographic key(s) and, when access to the cryptographic key is granted, execute a cryptographic function regarding at least a portion of the cryptographic key to produce a cryptographic result. The key store arbitration module is operable to determine whether the request to access the cryptographic key is valid; when the request is valid, interpret the request to produce an interpreted request; access the rule set memory based on the interpreted request to retrieve a rule of the set of rules; and grant access to the cryptographic key in accordance with the rule.
摘要（中）：
设备包括密钥存储器存储器，规则集存储器，多个密码客户端和密钥存储仲裁模块。 密钥存储存储器存储多个加密密钥，并且规则集存储器存储用于访问加密密钥的一组规则。 加密客户端可操作以发出访问加密密钥的请求，并且当授权对密码密钥的访问时，执行关于密码密钥的至少一部分的加密功能以产生加密结果。 密钥存储仲裁模块可操作以确定访问加密密钥的请求是否有效; 当请求有效时，解释请求以产生解释的请求; 基于解释的请求访问规则集存储器以检索该组规则的规则; 并根据规则授予对密码密钥的访问。
