🇺🇸 🇬🇧 AnyTone AT-D878UVII Plus - Vulnerability in DMR RC4 and AES encryption

If you are using the AnyTone ARC4 and AES encryption you should know that there is a vulnerability inside. This encryption is fully compatible with Motorola Enhanced Privacy ARC4/AES but its implementation is based on predictable initialization vectors (IV). In this video I explain you why these predictable IVs introduce a vulnerability and how a hacker can decipher your network without knowing your secret key. ------------------------------------------------------------------------------------------------------ ------------------------------------------------------------------------------------------------------ Video content: 00:00 Introduction 01:43 Disclaimer 02:17 The weakness identified : The first IV is always the same 03:46 The DMRA Enhanced Privacy ARC4 / AES encryption principle 05:28 The AnyTone encryption principle 06:51 Demonstration of the fixed IVs with DSD 12:12 How can a hacker decrypt voice ? 13:31 The process to hack AnyTone encryption 15:08 Why such vunlnerability ? 16:52 To know more about encryption, discover my online training on the subject 17:29 Conclusion 17:56 The final word ------------------------------------------------------------------------------------------------------ ------------------------------------------------------------------------------------------------------ Source code of DSD (Digital Speech Decoder) : https://github.com/LouisErigHerve/dsd Binaries pre-compiled for Windows (using Cygwin) : https://www.1geniesup.fr/index.php/dsd/ ------------------------------------------------------------------------------------------------------ ------------------------------------------------------------------------------------------------------ Discover my e-learning catalog (online training) : https://www.1geniesup.fr/en/online-tr...
