Threshold-Signed Service-Account Tokens for Kubernetes

At any time, one signing key signs every new service-account token in a Kubernetes cluster, and a copy of it lets an attacker mint tokens offline for any identity. We present an external signer that removes that key: it plugs into the stable ExternalJWTSigner interface (KEP-740)...

Service-Account Token Signing in Kubernetes

At any time, one active signing authority signs every new service-account token in a Kubernetes cluster. Whoever obtains that key can mint tokens that authenticate as any service account, offline and without contacting the cluster; authorization and admission control then evaluat...

Design and Synthesis of Purine–Biphenyl Hybrids: Cytotoxicity, ADMET Analysis and MD Simulation Study

A novel series of purine–biphenyl hybrids was designed and synthesized by linking 2,6-dichloropurine with methyl-2-cyanobiphenyl, aiming to develop cytotoxic agents targeting the Epidermal Growth Factor Receptor (EGFR). Structural diversity was introduced via C6 substitution with...

Performance and Tail-Latency Trade-offs Between Stateless JWT and Stateful Session Authentication Under Increasing Concurrency

Authentication architectures impose critical operational constraints on web service scalability. While stateless JSON Web Tokens (JWT) are operationally convenient, continuous cryptographic verification introduces computational overhead. Conversely, stateful session authenticatio...

Stress-Induced Protein Networks in Extremophilic Prokaryotes: Integrating Proteomics and Functional Genomics

Extremophilic prokaryotes survive salt, temperature, and pH extremes by coordinating stress-induced protein networks that preserve macromolecules, sustain energetics, and repair damage. This review integrates recent proteomics with functional genomics to resolve both network stat...
