I have read “How does order-preserving encryption work?”. After that, I completed order-preserving encryption on integer data.
Now, I have four questions in this subject:
- Is it possible to apply sum operation on encrypted integer data.
- Is it available for string data?
- Can i make string operations like finding an encrypted string in a ciphertext, order encrypted strings ... ?
- If order-preserving encryption is not suitable for these operations, Does any algrotihm make the job ?
