AES Based White Box Cryptography in Digital Signature Verification [PDF]
Sensors, 2022 According to the standard paradigm, white box cryptographic primitives are used to block black box attacks and protect sensitive information. This is performed to safeguard the protected information and keys against black box assaults.

On the Security Goals of White-Box Cryptography
Transactions on Cryptographic Hardware and Embedded Systems, 2020 We discuss existing and new security notions for white-box cryptography and comment on their suitability for Digital Rights Management and Mobile Payment Applications, the two prevalent use-cases of white-box cryptography.

Cryptanalysis of a white‐box SM4 implementation based on collision attack
IET Information Security, 2022 White‐box cryptography is to primarily protect the key of a cipher from being extracted in a white‐box scenario, where an adversary has full access to the execution environment of software implementation. Since the introduction of white‐box cryptography,

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).

Doubly Half-Injective PRGs for Incompressible White-Box Cryptography
Lecture Notes in Computer Science, 2019 White-box cryptography was originally introduced in the setting of digital rights management with the goal of preventing a user from illegally re-distributing their software decryption program. In recent years, mobile payment has become a popular new application for white-box cryptography. Here, white-box cryptography is used to increase the robustness

On the Ineffectiveness of Internal Encodings - Revisiting the DCA Attack on White-Box Cryptography
Lecture Notes in Computer Science, 2018 The goal of white-box cryptography is to implement cryptographic algorithms securely in software in the presence of an adversary that has complete access to the software’s program code and execution environment. In particular, white-box cryptography needs to protect the embedded secret key from being extracted. Bos et al.

ECDSA White-Box Implementations: Attacks and Designs from CHES 2021 Challenge
Transactions on Cryptographic Hardware and Embedded Systems, 2022 Despite the growing demand for software implementations of ECDSA secure against attackers with full control of the execution environment, scientific literature on ECDSA white-box design is scarce. The CHES 2021 WhibOx contest was thus held to assess the
