# kaal:claim:5225296-015

**Claim.** ECDSA introduces a vulnerability into SPoS through its dependence on secure random number generation at key creation, so the authentication guarantee fails when implementation departs from cryptographic best practice.

**Type.** failure  **Support.** argued

**Holds when.**

- when random number generation is improperly implemented

**Source quote.**

> However, ECDSA's reliance on secure random number generation for key creation introduces a potential vulnerability if improperly implemented, necessitating strict adherence to cryptographic best practices
