Tesla Autopilot, an advanced driver-assistance system for Tesla vehicles, uses a suite of sensors and an onboard computer. It has undergone several hardware changes and versions since 2014, most notably moving to an all-camera-based system by 2023, in contrast with ADAS from other companies, which include radar and sometimes lidar sensors.

The DES encryption used in NTLMv1 and MS-CHAPv2 to encrypt the NTLM password hash enable custom hardware attacks utilizing the method of brute force. [7] As of 2012, MS-CHAP had been completely broken. The divide-and-conquer attack only requires breaking a single DES key, which is not difficult with modern GPUs and FPGAs. [8]
Enhanced Autopilot (EAP) was announced later in 2016 as an extra-cost option that used a new hardware suite developed by Tesla; [16] the key distinguishing feature for EAP, "Navigate on Autopilot", which uses the new hardware suite to guide the vehicle on controlled-access roads, from on-ramp to off-ramp, was delayed until 2018.

In cryptography, a message authentication code (MAC), sometimes known as an authentication tag, is a short piece of information used for authenticating and integrity-checking a message. In other words, it is used to confirm that the message came from the stated sender (its authenticity) and has not been changed (its integrity).
The hardware of an autopilot varies between implementations, but is generally designed with redundancy and reliability as foremost considerations. For example, the Rockwell Collins AFDS-770 Autopilot Flight Director System used on the Boeing 777 uses triplicated FCP-2002 microprocessors which have been formally verified and are fabricated in a ...
Hardware-based encryption is the use of computer hardware to assist software, or sometimes replace software, in the process of data encryption. Typically, this is implemented as part of the processor 's instruction set.
BLAKE is a cryptographic hash function based on Daniel J. Bernstein's ChaCha stream cipher, but a permuted copy of the input block, XORed with round constants, is added before each ChaCha round. Like SHA-2 , there are two variants differing in the word size.
