标准范围

ISO/IEC 10116:2006规定了n位分组密码的操作模式。这些模式提供了用于加密和解密数据的方法，其中数据的比特长度可能超过分组密码的大小。ISO/IEC 10116:2006中规定的模式仅提供数据机密性保护。数据完整性保护和数据填充要求不在ISO/IEC 10116:2006的范围内。ISO/IEC 10116:2006规定了五种操作模式:电子密码本（ECB）；密码块链接(CBC)，具有可选的交织；密码反馈（CFB）；输出反馈（OFB）；和计数器（CTR）。ISO/IEC 10166:2006的附录提供了每种模式的对象标识符(根据ISO/IEC 9834)、每种模式的属性描述以及每种模式的图表和示例。在ISO/IEC 18033-3中规定了分组密码。

ISO/IEC 10116:2006 specifies modes of operation for an n-bit block cipher. These modes provide methods for encrypting and decrypting data where the bit length of the data may exceed the size of the block cipher. The modes specified in ISO/IEC 10116:2006 only provide protection of data confidentiality. Protection of data integrity and requirements for padding the data are not within the scope of ISO/IEC 10116:2006.ISO/IEC 10116:2006 specifies five modes of operation:

1. Electronic Codebook (ECB);
2. Cipher Block Chaining (CBC), with optional interleaving;
3. Cipher Feedback (CFB);
4. Output Feedback (OFB); and
5. Counter (CTR).

The Annexes of ISO/IEC 10166:2006 provide object identifiers (according to ISO/IEC 9834) for each mode, a description of the properties of each mode, and diagrams and examples of each mode.Block ciphers are specified in ISO/IEC 18033-3.
