    • A method for a plurality of key cache managers for a plurality of localities to share cryptographic key storage resources of a security chip, includes: loading an application key into the key storage; and saving a restoration data for the application key by a key cache manager, where the restoration data can be used by the key cache manager to re-load the application key into the key storage if the application key is evicted from the key storage by another key cache manager. The method allows each of a plurality of key cache managers to recognize that its key had been removed from the security chip and to restore its key. The method also allows each key cache manager to evict or destroy any key currently loaded on the security chip without affecting the functionality of other localities.
    • 一种用于多个地区的多个密钥高速缓存管理器用于共享安全芯片的加密密钥存储资源的方法,包括:将应用密钥加载到密钥存储器中; 并且由密钥高速缓存管理器保存用于应用密钥的恢复数据,其中如果应用密钥从另一个密钥存储器被逐出,密钥高速缓存管理器可以使用恢复数据将应用密钥重新加载到密钥存储器中 密钥缓存管理器。 该方法允许多个密钥高速缓存管理器中的每一个识别出其密钥已经从安全芯片中移除并恢复其密钥。 该方法还允许每个密钥缓存管理器驱逐或销毁安全芯片上当前加载的任何密钥,而不影响其他地方的功能。
