CAPEC 描述

An adversary exploits a cryptographic weakness in the signature verification algorithm implementation to generate a valid signature without knowing the key.

CAPEC 信息

前提条件

Recipient is using a weak cryptographic signature verification algorithm or a weak implementation of a cryptographic signature verification algorithm, or the configuration of the recipient's application accepts the use of keys generated using cryptographically weak signature verification algorithms.

所需技能

Cryptanalysis of signature verification algorithm
Reverse engineering and cryptanalysis of signature verification algorithm implementation

缓解措施

Use programs and products that contain cryptographic elements that have been thoroughly tested for flaws in the signature verification routines.

相关弱点
