-> 当InitSession、UpdateSession、FinishSession操作中的任一阶段发生错误时，都需要调用AbortSession操作来终止密钥的使用。 + 只有合法的业务才有权访问密钥，同时支持用户身份认证访问控制以支持业务的高安敏感场景下安全访问密钥的诉求。 +- **密钥的合法性证明** + 可为业务提供硬件厂商级别的密钥的合法性证明，证明密钥没有被篡改，并确实存在于有硬件保护的HUKS Core中，以及拥有正确的密钥属性。 + + +此外，密钥会话是HUKS中承载密钥使用的基础，它的主要作用是初始化密钥信息、缓存业务数据等。对数据的密码学运算和对密钥密文的加解密都是在HUKS Core中进行，以此保证密钥明文和运算过程的安全。 + +**图1** HUKS运行机制 + +![huks_architect](figures/huks_architect.png) ## 约束与限制 -不涉及。 + + - **基于别名的访问** + + 由于密钥材料不出HUKS的限制，应用只能以别名的方式访问密钥材料，而且密钥的别名必须保证应用内唯一(否则已存在的同别名密钥会被覆盖），长度不能超过64个字节。 + + - **数据分片大小限制** + + 所有数据需要经过IPC通道传输到HUKS，受IPC缓冲区大小限制，建议对总大小超过100K的数据进行分片传输，且分片大小不超过100K。 + + - **指定必选参数** + + 在**生成密钥或导入密钥时**，必须指定密码算法、密钥大小和使用目的参数，其他参数可选（如工作模式、填充模式、散列算法等），但是在**使用密钥**时必须传入密码算法相关的完整的参数。 + + - **密钥材料格式** + + 导入/导出密钥时（包括密钥对、公钥、私钥），密钥材料的数据格式必须满足HUKS要求的格式，具体各个密码算法密钥材料见[密钥材料格式](huks-appendix.md#密钥材料格式)。 + -- GitLab
