EUVD-2026-14375

Versions of the package jsrsasign before 11.1.1 are vulnerable to Improper Verification of Cryptographic Signature via the DSA domain-parameter validation in KJUR.crypto.DSA.setPublic and the related DSA/X509 verification flow in src/dsa-2.0.js. An attacker can forge DSA signatures or X.509...

Cryptanalysis of Four Arbitrated Quantum Signature Schemes

Arbitrated quantum signature AQS schemes aim at ensuring the authenticity of a message with the help of an arbitrator. Moreover, they aim at preventing repudiation, both from a sender that denies the origin of a message, and from a receiver who disavows its reception. Such protocols use quantum...
