Security & privacy Position · Theory · arXiv

Edge deployments that prioritize efficiency must re-evaluate safety and robustness after each optimization step, or risk deploying models that silently drop critical guardrails.

People & policy Measurement · Prototype · arXiv

The moderate willingness to adopt ECG authentication and the identified importance of familiarity, privacy, and clear onboarding suggest designers should prioritize user education and transparent data handling before deploying ECG-based passwordless systems.

People & policy Measurement · Real-world · arXiv

The findings show that existing third-party analytics on AI chatbots pose a concrete privacy risk, but platforms can mitigate it by removing or reconfiguring trackers, and users can protect themselves with standard script-blocking tools.

Security & privacy Measurement · Prototype · arXiv

Envelope-layer labels can improve LLM agent defenses, but their effectiveness is highly context-dependent and can be undermined by forged envelopes and agent memory, indicating that robust security requires holistic management of the entire agent context.

Security & privacy Theory · arXiv Threat model

The scheme offers a private-key FHE alternative with conditional ciphertext-only security, but practical deployment must address collision-harvest risks and the weak post-ideal security before it can replace lattice-based FHE in real applications.

AI/ML Defense · Prototype · arXiv Threat model

Janus demonstrates that automated cross-layer defense synthesis can markedly improve protection against deserialization attacks while maintaining functional performance, offering a practical path for operators to harden existing services.
