Metric

Description

Key size (for ~ 128-bit security)

The length of the cryptographic key required to achieve 128-bit security

Security level

The strength of encryption against attacks. Higher values indicate stronger security

Efficiency

The computational speed and resource usage of the encryption algorithm. Higher efficiency means faster processing

Latency

The time required to perform encryption or decryption

Implementation complexity

The difficulty of integrating the encryption algorithm in hardware or software

Hardware support

The level of optimization for running specialized hardware (e.g., FPGA, ASIC)

Resistance to side-channel attacks

The ability to withstand attacks that exploit hardware-level vulnerabilities like power consumption or timing analysis

Scalability

The ability to efficiently support large-scale applications or increasing data loads. Higher scalability ensures adaptability to different environments
