Mô tả CAPEC

An attacker, armed with the cipher text and the encryption algorithm used, performs an exhaustive (brute force) search on the key space to determine the key that decrypts the cipher text to obtain the plaintext.

Thông tin CAPEC

Luồng thực thi

1) Explore

Determine the ciphertext and the encryption algorithm.

2) Experiment

Perform an exhaustive brute force search of the key space, producing candidate plaintexts and observing if they make sense.

Điều kiện tiên quyết

Ciphertext is known.
Encryption algorithm and key size are known.

Kỹ năng cần thiết

Brute forcing encryption does not require much skill.

Tài nguyên cần thiết

Các biện pháp giảm thiểu

Use commonly accepted algorithms and recommended key sizes. The key size used will depend on how important it is to keep the data confidential and for how long.
In theory a brute force attack performing an exhaustive key space search will always succeed, so the goal is to have computational security. Moore's law needs to be taken into account that suggests that computing resources double every eighteen months.

Điểm yếu liên quan

CWE-ID Tên điểm yếu

CWE-326

Inadequate Encryption Strength
The product stores or transmits sensitive data using an encryption scheme that is theoretically sound, but is not strong enough for the level of protection required.

CWE-327

Use of a Broken or Risky Cryptographic Algorithm
The product uses a broken or risky cryptographic algorithm or protocol.

CWE-693

Protection Mechanism Failure
The product does not use or incorrectly uses a protection mechanism that provides sufficient defense against directed attacks against the product.

CWE-1204

Generation of Weak Initialization Vector (IV)
The product uses a cryptographic primitive that uses an Initialization Vector (IV), but the product does not generate IVs that are sufficiently unpredictable or unique according to the expected cryptographic requirements for that primitive.
