Why Cryptographic Systems Fail

Cryptographic systems can be vulnerable to outside attacks beyond the well-known brute-force attacks. Cryptographic main weaknesses come in two forms: weaknesses within the algorithm itself and weaknesses with their implementation. To clarify, the latter are called side-channel attacks.

Why are Cryptosystems Insecure?

Cryptosystems typically rely on random number generation to ensure that algorithms can’t be guessed or retrieved by outside forces. Essentially, this keeps the system secure and guarantees that only authorized personnel access the system via a secret password/phrase or key that only certain people know. Realistically, this key can be used to encrypt or decrypt data.

Many systems fail this random number generation, leading to severe vulnerabilities and the possibility of an entire security collapse. Furthermore, another issue is the security around handling a large number of secret keys or passwords and making sure that only the correct people have access to these.

But, even if only the proper people have access to the keys, breaches may still occur. In this case, people are also vulnerable to threats against their life, freedom, and families.

Unfortunately, these systems are also vulnerable to attacks by software programs or hackers. There are many different types of cryptographic attacks.

  • Dictionary attacks try to hack into the system using a list of compiled values to figure out passwords or secret keys.
  • Timing attacks involve outside parties observing lags in computer execution and taking advantage of this vulnerability
  • Chosen-plaintext attacks allow the hacker to access the ciphertexts by using random plaintext if the hacker has access to the encryption engine or can convince someone with access to encrypt the chosen plaintext.
  • Cryptanalytic software involves different software programs used to crack encryptions. These software programs include everything from side-channel attacks to brute-force attacks to keygens.

What to Do to Secure Cryptographic systems 

Cryptographic systems require constant vigilance to ensure that they are safe from vulnerabilities and breaches. Take the following precautions to protect software systems:

  • Only give secret keys to specific people: Only people who need access to these systems should have the keys. The fewer, the better, in fact.
  • Review algorithms: Make sure that your system is not suffering from a lousy algorithm setup. Correct the issue immediately upon discovery.
  • Verify adequate data encryption: Most important, administrators must determine that the system is encrypting appropriate data without leaving any critical data vulnerable to attack.
  • Hire a firm to test your security: iBeta offers security testing to determine where application and network vulnerabilities exist on your systems.
