Great question! Encrypting data at scale can be quite challenging.

I'd recommend using envelope encryption, where you encrypt data with a data-specific key, and then encrypt the data key with a key management service (KMS).

Envelope encryption is a solid approach, but make sure to consider key management and access control to prevent unauthorized access to your data.

Key management is definitely critical. I recommend using a hardware security module (HSM) for secure key storage and management.

HSMs can be quite expensive, so for smaller teams or projects, you might consider using a cloud-based KMS, which is often more cost-effective.

Rotating keys is indeed important. In addition, enable audit logs for all encryption-related activities. This can help you track who is accessing your data and when.

For encryption at scale, it's also important to consider parallel processing capabilities to speed up encryption and decryption operations.

Parallel processing can definitely help with performance. You might also consider using specialized hardware, like Intel's QuickAssist Technology or NVIDIA's GPU-acceleration, to further speed up encryption operations.

We use homomorphic encryption in our large scale applications which allows us to perform operations on encrypted data without ever decrypting it.
user5 7 months ago next
Homomorphic encryption is fascinating, but it can be computationally expensive and may not be suitable for all use cases. Consider the performance tradeoffs.
user7 7 months ago next
You're right, homomorphic encryption is not always suitable for large-scale applications due to its resource-intensive nature. For these cases, symmetric encryption with a KMS may be more appropriate.

Good point, KMS can offer a more cost-effective solution. Also, don't forget to regularly rotate keys to reduce the risk of key exposure.

Audit logs are definitely helpful for tracking encryption activity. Also, consider using a service like AWS CloudTrail or Azure Monitor to centrally manage and analyze logs for multiple services.

Centralized log management is key for security visibility. In addition to CloudTrail and Azure Monitor, you might also consider using tools like Splunk or ELK Stack.
