Regulations
Business Context
Encryption protects industrial communications against interception and
tampering. Encryption processes, however, introduce additional
computational overhead that may affect time-sensitive industrial
communications.
The Contradiction
Stronger encryption improves cybersecurity.
Lower communication latency improves operational performance.
Why It Exists
Real-time industrial control systems require deterministic
communications, while encryption inevitably adds processing time.
Direction
Apply encryption according to communication criticality, using hardware
acceleration and optimized industrial security protocols where
deterministic performance is essential.
