抗量子加密如何保護我的交易？

Quantum-resistant encryption protects cryptocurrency transactions through two mechanisms: key encapsulation (using Kyber) secures communication and key derivation, while digital signatures (using SPHINCS+) authorize transactions. Together they protect who can spend against quantum attacks; confidentiality applies only to optional shadow sends, because ordinary SynX sends are transparent by default.

Bitcoin itself is signed, not encrypted: is Bitcoin encrypted? What quantum computers actually break.

Kyber-768 的金鑰封裝在錢包組件和網路節點之間建立了安全通道。當您的錢包與網路通訊時，Kyber 會建立一個加密通道的共享金鑰。量子電腦無法透過破壞金鑰交換來攔截這種通信，因為 Kyber 的基於晶格的結構會抵制 Shor 的演算法。

Digital signatures with SPHINCS+ prove transaction authorization. Each transaction carries a signature proving that the private key holder—and only that holder—approved the fund transfer. SPHINCS+ signatures cannot be forged even with quantum computing capabilities, as their security rests on hash functions, which Grover's algorithm only weakens and Shor's algorithm does not touch.

保護生命週期涵蓋：交易創建（錢包構造傳輸詳細資訊）、簽名（使用私鑰應用 SPHINCS+ 簽名）、傳輸（與節點進行 Kyber 安全通訊）、驗證（節點驗證 SPHINCS+ 簽名）和記錄（交易包含在區塊中，簽名永久保留）。

Passive attackers harvesting SynX data cannot use it to derive private keys later, although ordinary sends are public by design. Future quantum computers cannot derive private keys from public keys or signatures. The "harvest now, decrypt later" threat is neutralized for quantum-resistant transactions.

主動攻擊者無法偽造交易。如果沒有私鑰，創建有效的 SPHINCS+ 簽章對於經典計算機和量子計算機來說在計算上都是不可行的。嘗試偽造簽名驗證失敗。

SynX 交易在整個交易生命週期中受益於 Kyber-768 金鑰封裝和 SPHINCS+ 簽名。從錢包到區塊鏈的每項操作都受到 NIST 標準化抗量子密碼學的保護。
