Abstract: Example embodiments provide various techniques for locating cryptographic keys stored in a cache. The cryptographic keys are temporarily stored in the cache until retrieved for use in a cryptographic operation. The cryptographic key may be located or found through reference to its cryptographic key identifier. In an example, a particular cryptographic key may be needed for a cryptographic operation. The cache is first searched to locate this cryptographic key. To locate the cryptographic key, the cryptographic key identifier that is associated with this cryptographic key is provided. In turn, the cryptographic key identifier may be used as an address into the cache. The address identifies a location of the cryptographic key within the cache. The cryptographic key may then be retrieved from the cache at the identified address and then used in the cryptographic operation.

Abstract translation: 示例性实施例提供了用于定位存储在高速缓存中的加密密钥的各种技术。 加密密钥临时存储在高速缓存中，直到被检索以用于加密操作。 加密密钥可以通过参考其加密密钥标识符来定位或发现。 在一个示例中，密码操作可能需要特定的密码密钥。 首先搜索缓存以查找此加密密钥。 为了定位加密密钥，提供与该加密密钥相关联的加密密钥标识符。 反过来，密码密钥标识符也可以用作高速缓存中的地址。 地址标识高速缓存中密码密钥的位置。 然后可以从所识别的地址的高速缓存中检索加密密钥，然后在密码操作中使用。
