Last revision (mm/dd/yy): 02/21/2009
Attempting to create non-standard and non-tested algorithms, using weak algorithms, or applying algorithms incorrectly will pose a high weakness to data that is meant to be secure.
- Confidentiality: The confidentiality of sensitive data may be compromised by the use of a broken or risky cryptographic algorithm.
- Integrity: The integrity of sensitive data may be compromised by the use of a broken or risky cryptographic algorithm.
- Accountability: Any accountability to message content preserved by cryptography may be subject to attack.
- Design: The decision as to what cryptographic algorithm to utilize is generally made at design time.
- Languages: All
- Operating platforms: All
Likelihood of exploit
Medium to High
Since the state of cryptography advances so rapidly, it is common to find algorithms, which previously were considered to be safe, currently considered unsafe. In some cases, things are discovered, or processing speed increases to the degree that the cryptographic algorithm provides little more benefit than the use of no cryptography at all.
- Use of custom cryptographic algorithms.
- Use of weak and/or untested public algorithms.
Cipher des=Cipher.getInstance("DES...); des.initEncrypt(key2);
- Design: Use a cryptographic algorithm that is currently considered to be strong by experts in the field.
