Performance Analysis of Multiparty GHZ-State Quantum Conference Key Agreement over Optical Fiber Channel

Quantum conference key agreement QCKA enables multiple spatially separated users to establish a common key with composable information-theoretic security by exploiting multipartite quantum correlations. Greenberger--Horne--Zeilinger GHZ states are a natural resource for this task, but their...

CVE-2026-105222: Improper Certificate Validation

The alexpechkarev/google-maps Laravel package through 12.16 disables TLS certificate verification by default because the bundled config sets sslverifypeer to FALSE, which is passed to CURLOPTSSLVERIFYPEER. On-path attackers can present any certificate to intercept Google Maps web-service requests...
