Digital-Signature-Forgery-Attack

在本文中，我们将探讨数字签名伪造攻击（Digital Signature Forgery Attack）的密码学原理，其后果对比特币网络中的交易安全构成威胁，因为数字签名用于确认加密货币转账的所有权和授权。我们将根据现代研究和已识别的漏洞，分析此类攻击对比特币的影响示例。 数字签名伪造攻击（Digital Signature Forgery Attack）是指攻击者试图创建一个被比特币网络视为有效的虚假 ECDSA 数字签名。这种攻击允许在不知道所有者私钥的情况下授权交易，从而危及 BTC 币持有者加密钱包中资金的安全。 教程：https://youtu.be/qbu1mC1wyA...

CVE-2026-22001-SPHINCS-WOTS-Weak-Randomness-Forgeable-Signature

CVE-2026-22001 – SPHINCS+ WOTS+ 弱随机性签名伪造 概述 SPHINCS+ 后量子签名方案的一种实现，在生成 WOTS+ 签名时使用了有缺陷的随机数生成器。同一 nonce k 在多个签名中被重复使用，使攻击者能够恢复私钥并伪造任意消息。 漏洞详情 类型： 加密随机性失败 影响： 完全密钥泄露、签名伪造。 根本原因： WOTS+ 签名算法依赖于每次签名使用唯一的随机值 k。k 的重复使用会泄露可揭示种子的代数关系。 漏洞利用演示 运行模拟： root@kitploit: python sphincsforge.py python...

DEBIAN-CVE-2026-87733

An issue was discovered in the mirage-crypto-ec function before 2.2.0 for OCaml. The ECDSA functions P256,P384,P521.Dsa.pubofoctets accept 0x00, the encoding of the point at infinity, as a public key. With that public key, signatures can be forged without a private key...

CVE-2026-87733

mirage-crypto-ec for OCaml , versions before 2.2.0 , contains a flaw in the ECDSA functions {P256, P384, P521}.Dsa.pub_of_octets. The function accepts 0x00 —the encoding of the point at infinity —as a valid public key, allowing an attacker to forge ECDSA signatures without knowledge of the privat...

CVE-2026-67276

RouterOS does not compare the complete RSA public key when matching an SSH authentication request to an authorized user key, checking the key type and modulus but omitting the exponent. Because signature verification uses the client-supplied key, an attacker knowing an authorized RSA modulus can...

CVE-2026-67278

MikroTik RouterOS accepts malformed RSA/PKCS#1 v1.5 signatures during X.509 validation. Because its trust store includes a root CA with e=3 , an attacker who controls or redirects an outbound TLS connection can use the root's public certificate—without its private key—to forge a trusted intermedi...
