Watermarking PRFs from Lattices: Stronger Security via Extractable PRFs
ADVANCES IN CRYPTOLOGY - CRYPTO 2019, PT III, pp. 335-366, 2019.
A software watermarking scheme enables one to embed a "mark" (i.e., a message) within a program while preserving the program's functionality. Moreover, there is an extraction algorithm that recovers an embedded message from a program. The main security goal is that it should be difficult to remove the watermark without destroying the func...More
