The Impact of Digit Semantic Patterns on Password Security
- Published
- Record updated
Summary
Researchers found that password strength meters in mainstream IoT systems overestimate passwords containing digit segments. They extracted high-frequency digit semantic patterns and used them to improve a PCFG attack, showing that these semantic characteristics strongly affect password strength. The authors also propose an improved password strength meter for IoT systems based on those patterns.
Mitigation
The authors propose a feasible scheme to improve the password strength meter for IoT systems based on the high-frequency semantic characteristics of digit segments.
