Key sensitivity analysis

Sensitivity level

Impact on security

Length of fractal key

High

Longer key provide increased security

Key rotation Frequency

Medium

More frequent rotation enhances security

Complexity of fractal

High

More complex fractals increase security

External key exposure

High

Exposure increases vulnerability

Encryption algorithm

Medium

The strength of the algorithm impacts security
