We present a general compiler to add the publicly verifiable deletion property for various cryptographic primitives including public key encryption, attribute-based encryption, and quantum fully homomorphic encryption. Our compiler only uses one-way functions, or more generally hard quantum planted problems for NP, which are implied by one-way functions. It relies on minimal assumptions and enables us to add the publicly verifiable deletion property with no additional assumption for the above primitives. Previously, such a compiler needs additional assumptions such as injective trapdoor one-way functions or pseudorandom group actions [Bartusek-Khurana-Poremba, ePrint:2023/370]. Technically, we upgrade an existing compiler for privately verifiable deletion [Bartusek-Khurana, ePrint:2022/1178] to achieve publicly verifiable deletion by using digital signatures.
翻译:我们提出了一种通用编译器,用于为各种密码原语(包括公钥加密、基于属性的加密和量子完全同态加密)添加“可公开验证删除”属性。我们的编译器仅使用单向函数,或更一般地使用 NP 中的困难量子种植问题,这些问题被单向函数所蕴含。它依赖于最小假设,使我们能够在上述原语中添加“可公开验证删除”属性,而无需其他假设。以前,这样的编译器需要额外的假设,例如可注入陷门单向函数或伪随机群操作[Bartusek-Khurana-Poremba,ePrint:2023/370]。从技术上讲,我们通过使用数字签名,将现有的用于私密可验证删除的编译器[Bartusek-Khurana,ePrint:2022/1178]升级为可公开验证删除。
