On the Linear Transformation in White-Box Cryptography [PDF]
IEEE Access, 2020 A linear transformation is applied to the white-box cryptographic implementation for the diffusion effect to prevent key-dependent intermediate values from being analyzed.

Structural Attack (and Repair) of Diffused-Input-Blocked-Output White-Box Cryptography
Transactions on Cryptographic Hardware and Embedded Systems, 2021 In some practical enciphering frameworks, operational constraints may require that a secret key be embedded into the cryptographic algorithm. Such implementations are referred to as White-Box Cryptography (WBC).

White-Box Cryptography: A Time-Security Trade-Off for the SPNbox Family
, 2019 White-box cryptography aims to ensure the security of cryptographic algorithms in an untrusted environment where the adversary has full access to their implementations. Typical applications are DRM, Pay Tv boxes, and smartphones. A number of white-box implementations for standard cryptographic algorithms—e.g., AES and DES—have been published in the ...

Towards Secure and Efficient "white-box" Encryption [PDF]
Journal of Universal Computer Science, 2019 In many applications implemented in mistrusted environments all operations with the secret key during an encryption operation are "obfuscated" in a way that while an attacker has access to all routines of operations, it will nevertheless be ...

On Provable White-Box Security in the Strong Incompressibility Model
Transactions on Cryptographic Hardware and Embedded Systems, 2023 Incompressibility is a popular security notion for white-box cryptography and captures that a large encryption program cannot be compressed without losing functionality. Fouque, Karpman, Kirchner and Minaud (FKKM) defined strong incompressibility, where

On White-box Cryptography and Obfuscation
CoRR, 2008 We study the relationship between obfuscation and white-box cryptography. We capture the requirements of any white-box primitive using a \emph{White-Box Property (WBP)} and give some negative/positive results. Loosely speaking, the WBP is defined for some scheme and a security notion (we call the pair a \emph{specification}), and implies that w.r.t ...

White-Box Cryptography and an AES Implementation [PDF]
, 2003 Conventional software implementations of cryptographic algorithms are totally insecure where a hostile user may control the execution environment, or where co-located with malicious software. Yet current trends point to increasing usage in environments so threatened.
