Jan 13, version: This importance stems from several reasons: Similar theoretic approaches have been conceived for white-box cryptography in [Sax09]. On the Impossibility of Obfuscation with Auxiliary Input. Indeed, it does not suffice to only protect an application against extraction of embedded secret keys.

Research Academic research in white-box cryptography can be categorized into three activities. Jan 13, version: 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. Obfuscation for Cryptographic Purposes. Patrick Wagner, copromotors are Prof. 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.

Due to these reasons a general interest in fast, label-free, low-cost and user-friendly DNA sensors has emerged.

ITCC 1pages Obfuscation for Cryptographic Purposes. Ran Canetti and Mayank Varia. Chand Gupta, and G. Research Academic research in white-box cryptography can be categorized into three activities. One of the central challenges in genomics is the detection and identification of single nucleotide polymorphisms SNPs.

Similar theoretic approaches have been conceived for white-box cryptography in [Sax09]. Indeed, it does not suffice to only protect an application against extraction of embedded secret keys. Both have received similar scepticism on its feasibility and lack of theoretic foundations.

Resources Slides March — slides PhD defense. On the Impossibility of Obfuscation with Auxiliary Input.

The main difference between code obfuscation and white-box cryptography is that the security of the latter needs to be validated with respect to theis notions. Nevertheless, this result does not exclude the existence of secure code obfuscators: On the Im possibility of Obfuscating Programs.

Bart Michiels – Wikipedia

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. Wyseur, and Bart Preneel: This importance stems from several reasons: A security notion is a formal description of the security of a cryptographic scheme.

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.

White-box implementations and cryptanalysis results A selection of the state of the art: Theory White-box cryptography is often linked with code obfuscation, since both aim to protect software implementations.

Shafi Goldwasser and Yael Tauman Kalai. Established technologies exist to identify these SNPs, but several disadvantages need consideration. Theoretic research on code obfuscation gained momentum with the seminal mcihiels of Barak et al.

Jan 13, version: 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.

This thesis reports on the development of DNA sensors that respond to these specifications It makes sense to define white-box cryptography accordingly since it reflects more reality. On Obfuscating Point Functions. Attacking an obfuscated cipher by injecting faults. Positive Results and Techniques for Obfuscation. 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.
