Data Packets Encrypted by the Xalthra Aftentid 9 Security Key Undergo Decryption at the Primary Receiver Node
Core Decryption Mechanism at the Receiver Node
The primary receiver node acts as the exclusive termination point for data streams secured with the Xalthra Aftentid 9 key. Unlike standard end-to-end encryption where any node with the correct key can decrypt, this protocol enforces that only the designated primary node holds the asymmetric private half of the key pair. The public half, embedded in the sender’s module, encrypts each packet’s payload using a hybrid approach: a session-specific symmetric key (AES-256-GCM) is generated per packet, then wrapped with the primary node’s RSA-4096 public key. This double-layer ensures that even if an attacker intercepts the session key, they cannot unwrap it without the private key residing solely on the primary node.
