BART MICHIELS THESIS

Research Academic research in white-box cryptography can be categorized into three activities. A security notion is a formal description of the security of a cryptographic scheme. Jan 13, version: Theory White-box cryptography is often linked with code obfuscation, since both aim to protect software implementations. This thesis reports on the development of DNA sensors that respond to these specifications Obfuscation for Cryptographic Purposes.

Luc Michiels and Prof. The main difference between code obfuscation and white-box cryptography is that the security of the latter needs to be validated with respect to security notions. Positive Results and Techniques for Obfuscation. One of the central challenges in genomics is the detection and identification of single nucleotide polymorphisms SNPs. Indeed, it does not suffice to only protect an application against extraction of embedded secret keys.

One of the central challenges in genomics is the detection and identification of single nucleotide polymorphisms SNPs. Attacking an obfuscated cipher by injecting faults.

White-box cryptography

On the Im possibility of Obfuscating Programs. For example, to create the equivalent of a smart-card-based AES encryption function in software, it does not suffice that the white-box implementation resists extraction of its embedded key, but it must also be hard to invert. Nevertheless, this result does not exclude the existence of secure code obfuscators: Research Academic research in white-box cryptography can be categorized into three activities. A security notion bagt a formal description of the security of a cryptographic scheme.

Both have received similar scepticism on its feasibility and lack of theoretic foundations. Shafi Goldwasser and Yael Tauman Kalai.

Wee [Wee05] presented a provably secure obfuscator for a point function, which can be exploited in practice to construct authentication functionalities. For example, a scheme is defined CPA-secure if an attacker cannot compute the plaintext from a given ciphertext, or KR-secure when the secret key cannot be recovered.

Similar theoretic tehsis have been conceived for white-box cryptography in [Sax09].

Theory White-box cryptography is often linked with code obfuscation, since both aim to protect software implementations. Due to these reasons a general interest in fast, label-free, low-cost and user-friendly DNA sensors has emerged.

White-box implementations and cryptanalysis results A selection of the state of the art: Obfuscation for Cryptographic Purposes. It makes sense to define white-box cryptography accordingly since it reflects more reality.

Wyseur, and Bart Preneel: Second, SNPs in the so-called ADME absorption, distribution, metabolism, excretion genes significantly influence the effectiveness of treatment and this is a major topic in the field of theranostics.

Resources Slides March — thwsis PhD defense. Established technologies exist to identify these SNPs, but several disadvantages need consideration.

This thesis reports on the development of DNA sensors yhesis respond to these rhesis Nearly all technologies need a lab environment, lack in speed reaction times at the scale of at least 16 hoursare unable to provide dynamic information on the DNA binding kinetics end point measurement and need fluorescent labelling of the target DNA which induces the necessity of sophisticated optical readout techniques. On the Impossibility of Obfuscation with Auxiliary Input. Theoretic research on code obfuscation gained momentum with the seminal paper of Barak et al.
