What To Expect From High Court's Whistleblower Case
by Gunnar Larson 11 Jul '23

11 Jul '23

What To Expect From High Court's Whistleblower Case The U.S. Supreme Court's upcoming decision in Murray v. UBS Securities will likely have widespread implications for the future of anti-retaliation whistleblower litigation, and could make it more difficult for would-be whistleblower-employees to succeed on anti-retaliation claims under the Sarbanes-Oxley Act, say Ann-Elizabeth Ostrager and Diane McGimsey at Sullivan & Cromwell.

[pq] grad thesis DGMT: A Fully Dynamic Hash-Based Group Signature

Shor’s quantum algorithms for breaking discrete logarithm (DL) and integer factorization (IF) problems will bring depredation for currently used public key algorithms, including RSA (Rivest–Shamir–Adleman), DH (Diffie-Hellman) key agreement, DSA (Digital Signature Algorithm) and ECC (Elliptic Curve Cryptography), which their security depends on solving mathematical hard problems (IF and DL problem). Therefore, applications and protocols must evolve to be quantum secure in the presence of quantum computers. It is believed that symmetric encryptions and hash functions are resilient to attacks by a quantum adversary. Therefore, signature schemes have been modified so that their security relies on hash functions instead of the aforementioned mathematical hard problems. In this thesis, we consider post-quantum digital group signatures, whose security depends on one-way functions. In practice, these functions are replaced by cryptographic hash functions, which are expected to remain secure in the presence of quantum computers. A group signature is a signature scheme that allows a group member to anonymously sign messages on behalf of the group, while anonymity can be annulled by an opening authority or group manager. In fully dynamic group signature schemes, new members can be added to the group after the initialization phase and existing members can be revoked from the group. The primary aim of this thesis is twofold. Firstly, it aims to conduct a comprehensive analysis of various hash-based group signature schemes, taking into consideration their security models, properties, and limitations. Moreover, this thesis contributes to the development of a novel fully dynamic group signature scheme, named DGMT, which addresses the limitations of previous schemes, and we prove its security (unforgeability, anonymity, and traceability), and provide the complete implementation of the this scheme for the first time. Secondly, the thesis intends to review and evaluate various revocation methods with the objective of identifying potential ways to improve the revocation method utilized in the proposed scheme

[random] Somebody's Dissertation Involving AES Template Attacks
by Undescribed Horrific Abuse, One Victim & Survivor of Many 11 Jul '23

11 Jul '23

O_O To carry out the evaluation, the work analyzes the SCA of AES-CTR in a few hardware and software implementations. This study uses two hardware devices: a microcontroller board with an arm Cortex-M4F chip and a System-on-Chip (SoC) CoraZ7 board from Xilinx. The power trace acquisition method was used to collect trace sets on the microcontroller, and the electromagnetic method was used to collect trace sets on both microcontroller and the SoC. The findings of this study present a novel approach that improves points of interest selection for template attacks. The improved point of interest (POI) selection algorithm developed in this work compares the output from multiple points of interest using the same method to get the best samples that yield the correct key hypothesis.
