在大型数据库中加密个人身份信息（PII）历来是困难的，因为加密信息通常意味着扩展数据并更改其格式。以前尝试加密PII数据（如信用卡号码和社会安全号码）而不改变其格式的尝试使用了有问题的加密结构。我们研究了这个问题的安全模型，扩展了Black和Rogaway的构造，并提出了加密信用卡号码和社会安全号码的实用构造。
Encrypting Personally Identifiable Information (PII) in large databases has historically been difficult, because encrypting information typically implies expanding data and changing its format. Previous attempts to encrypt PII data like credit card numbers and Social Security Numbers without changing their format have used questionable cryptographic constructions. We examine the security model for this problem, extend a construction by Black and Rogaway, and propose practical constructions for encrypting credit card numbers and Social Security Numbers.
