Blindfold: Sum Operation
The "sum" operation is a one-way operation used to perform secure addition on encrypted integers using homomorphic encryption.
Expected sum: 3
CONFIGURATION
12345678
KEY TYPE
SecretKey Seed
Same seed = same key = reproducible encryption
OUTPUT
SUM OPERATION REFERENCE
SINGLE NODE
Implementation: Non-deterministic Paillier with 2048-bit primes
Types: 32-bit signed integer only
Security: Homomorphic encryption allows addition without decryption
MULTIPLE NODES
Implementation: Additive secret sharing (prime modulus 2^32 + 15)
Types: 32-bit signed integer only
WORKFLOW
1. Encrypt:Each number encrypted to shares/ciphertext
2. Compute:Addition performed on encrypted values
3. Decrypt:Final sum revealed without exposing inputs
