"value": "The Noise protocol implementation suffers from weakened cryptographic security after encrypting 2^64 messages, and a potential denial of service attack. After 2^64 (~18.4 quintillion) messages are encrypted with the Encrypt function, the nonce counter will wrap around, causing multiple messages to be encrypted with the same key and nonce. In a separate issue, the Decrypt function increments the nonce state even when it fails to decrypt a message. If an attacker can provide an invalid input to the Decrypt function, this will cause the nonce state to desynchronize between the peers, resulting in a failure to encrypt all subsequent messages."

Despu\u00e9s de cifrar 2^64 (~18,4 quintillones) de mensajes con la funci\u00f3n Encrypt , el contador nonce se ajustar\u00e1, lo que provocar\u00e1 que se cifren varios mensajes con la misma clave y nonce. En un tema aparte, la funci\u00f3n Decrypt incrementa el estado nonce incluso cuando no logra descifrar un mensaje. Si un atacante puede proporcionar una entrada no v\u00e1lida a la funci\u00f3n Decrypt, esto har\u00e1 que el estado nonce se desincronice entre los pares, lo que resultar\u00e1 en un fallo al cifrar todos los mensajes posteriores."
