Module threshold_decryption 

Threshold decryption coordinator.

Coordinates ElGamal-style threshold decryption: collect decryption shares from T parties and combine them into the full plaintext.

Structs

DecryptionSession

A threshold decryption session.

DecryptionShare

A decryption share from one party.

Enums

DecryptionError

Errors during threshold decryption.

Functions

combine_shares

Combine decryption shares using Lagrange interpolation. In a real implementation, this would use the group operation (e.g., EC point addition weighted by Lagrange coefficients). Here, we XOR-combine for the mock case.
