In cryptography, encryption is the process of encoding messages or information in such a way that only authorized parties can read it. Encryption does not of itself prevent interception, but denies the message content to the interceptor. In an encryption scheme, the intended communication information or message, referred to as plaintext, is encrypted using an encryption algorithm, generating ciphertext that can only be read if decrypted. For technical reasons, an encryption scheme usually uses a pseudo-random encryption key generated by an algorithm. It is in principle possible to decrypt the message without possessing the key, but, for a well-designed encryption scheme, large computational resources and skill are required. An authorized recipient can easily decrypt the message with the key provided by the originator to recipients, but not to unauthorized interceptors.

Three-quarters of the federal government uses encryption. Homeland Security says that isn't enough.
Wi-Fi Protected Access(WPA,more commonly WPA2)handshake traffic can be manipulated to induce nonce and session key reuse,resulting in key reinstallation by a wireless access point(AP)or client.

An attacker within range of an affected AP and client may leverage these vulnerabilities to conduct attacks that are dependent on the data confidentiality protocols being used.

Attacks may include arbitrary packet decryption and injection,TCP connection hijacking,HTTP content injection,or the replay of unicast and group-addressed frames.

These vulnerabilities are referred to as Key Reinstallation Attacks orKRACKattacks.
Factorization weakness lets attackers impersonate key holders and decrypt their data.
KRACK attack allows other nasties, including connection hijacking and malicious injection.
You only need to look at the past year of data breaches, leaks, and exposures to see that some of the most precious national security and technological secrets in the US aren't safe.
