抗量子加密如何保护我的交易？

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 的密钥封装在钱包组件和网络节点之间建立了安全通道。当您的钱包与网络通信时，Kyber 会创建一个加密通道的共享密钥。量子计算机无法通过破坏密钥交换来拦截这种通信，因为 Kyber 的基于晶格的结构会抵制 Shor 的算法。

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.

保护生命周期涵盖：交易创建（钱包构造传输详细信息）、签名（使用私钥应用 SPHINCS+ 签名）、传输（与节点进行 Kyber 安全通信）、验证（节点验证 SPHINCS+ 签名）和记录（交易包含在块中，签名永久保留）。

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.

主动攻击者无法伪造交易。如果没有私钥，创建有效的 SPHINCS+ 签名对于经典计算机和量子计算机来说在计算上都是不可行的。尝试伪造签名验证失败。

SynX 交易在整个交易生命周期中受益于 Kyber-768 密钥封装和 SPHINCS+ 签名。从钱包到区块链的每项操作都受到 NIST 标准化抗量子密码学的保护。
