Mô tả CAPEC

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

Thông tin CAPEC

Điều kiện tiên quyết

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.

Kỹ năng cần thiết

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

Các biện pháp giảm thiểu

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