PDLRecover: Privacy-preserving Decentralized Model Recovery with Machine Unlearning
Decentralized learning is vulnerable to poison attacks, where malicious clients manipulate local updates to degrade global model performance. Existing defenses mainly detect and filter malicious models, aiming to prevent a limited number of attackers from corrupting the global model. However,...
CVE-2022-50036
In the Linux kernel, the following vulnerability has been resolved: drm/sun4i: dsi: Prevent underflow when computing packet sizes Currently, the packet overhead is subtracted using unsigned arithmetic. With a short sync pulse, this could underflow and wrap around to near the maximal u16 value. Fi...
CVE-2025-43863 vantage6 lacks brute-force protection on change password functionality
vantage6 is an open source framework built to enable, manage and deploy privacy enhancing technologies like Federated Learning and Multi-Party Computation. If attacker gets access to an authenticated session, they can try to brute-force the user password by using the change password functionality...

Commitment Schemes for Multi-Party Computation
The paper presents an analysis of Commitment Schemes CSs used in Multi-Party Computation MPC protocols. While the individual properties of CSs and the guarantees offered by MPC have been widely studied in isolation, their interrelation in concrete protocols and applications remains mostly...
Security Bulletin: IBM DataPower Gateway affected by timing side-channel in OpenSSL (CVE-2024-13176)
Summary IBM DataPower Gateway uses OpenSSL for most cryptographic operations. Vulnerability Details CVEID:CVE-2024-13176 DESCRIPTION: Issue summary: A timing side-channel which could potentially allow recovering the private key exists in the ECDSA signature computation. Impact summary: A timing...
Security Bulletin: This Power System update is being released to address CVE-2024-13176
Summary This affects the BMC's HTTPS and SSH interfaces. Vulnerability Details CVEID:CVE-2024-13176 DESCRIPTION: Issue summary: A timing side-channel which could potentially allow recovering the private key exists in the ECDSA signature computation. Impact summary: A timing side-channel in ECDSA...
Secure Distributed Learning for CAVs: Defending against Gradient Leakage with Leveled Homomorphic Encryption
Federated Learning FL enables collaborative model training across distributed clients without sharing raw data, making it a promising approach for privacy-preserving machine learning in domains like Connected and Autonomous Vehicles CAVs. However, recent studies have shown that exchanged model...
Securing Unbounded Differential Privacy against Timing Attacks
Recent works have started to theoretically investigate how we can protect differentially private programs against timing attacks, by making the joint distribution the output and the runtime differentially private JOT-DP. However, the existing approaches to JOT-DP have some limitations, particular...
Synopsis: Secure and Private Trend Inference from Encrypted Semantic Embeddings
WhatsApp and many other commonly used communication platforms guarantee end-to-end encryption E2EE, which requires that service providers lack the cryptographic keys to read communications on their own platforms. WhatsApp's privacy-preserving design makes it difficult to study important phenomena...
Chainless Apps: a Modular Framework for Building Apps with Web2 Capability and Web3 Trust
Modern blockchain applications are often constrained by a trade-off between user experience and trust. Chainless Apps present a new paradigm of application architecture that separates execution, trust, bridging, and settlement into distinct compostable layers. This enables app-specific sequencing...
Privacy-Preserving Inconsistency Measurement
We investigate a new form of privacy-preserving inconsistency measurement for multi-party communication. Intuitively, for two knowledge bases KA, KB of two agents A, B, our results allow to quantitatively assess the degree of inconsistency for KA U KB without having to reveal the actual contents ...
Towards a DSL for Hybrid Secure Computation
Fully homomorphic encryption FHE and trusted execution environments TEE are two approaches to provide confidentiality during data processing. Each approach has its own strengths and weaknesses. In certain scenarios, computations can be carried out in a hybrid environment, using both FHE and TEE...
CVE-2024-21671
The vantage6 technology enables to manage and deploy privacy enhancing technologies like Federated Learning FL and Multi-Party Computation MPC. It is possible to find out usernames from the response time of login requests. This could aid attackers in credential attacks. Version 4.2.0 patches this...
CVE-2024-23218
A timing side-channel issue was addressed with improvements to constant-time computation in cryptographic functions. This issue is fixed in iOS 16.7.6 and iPadOS 16.7.6, iOS 17.3 and iPadOS 17.3, macOS Monterey 12.7.4, macOS Sonoma 14.3, macOS Ventura 13.6.5, tvOS 17.3, watchOS 10.3. An attacker...
CVE-2024-22193
The vantage6 technology enables to manage and deploy privacy enhancing technologies like Federated Learning FL and Multi-Party Computation MPC. There are no checks on whether the input is encrypted if a task is created in an encrypted collaboration. Therefore, a user may accidentally create a tas...
CVE-2024-24770
vantage6 is an open source framework built to enable, manage and deploy privacy enhancing technologies like Federated Learning and Multi-Party Computation. Much like GHSA-45gq-q4xh-cp53, it is possible to find which usernames exist in vantage6 by calling the API routes /recover/lost and /2fa/lost...
