Encrypted Title Key is an encrypted key that belongs to anticopy Advanced Access Content System (AACS). This key is included in the Media Key Block system and is an important part of the content protection process of Blu-ray and HD-DVD contents.
Replacement keys, which can be purchased through the dealer or a 3rd party, must be compatible with the vehicle. Before the key can be used to start the vehicle it must be programmed, done by inserting the original key(s) as well as the new key into the ignition. With PATS I, programming of a new key can be done with just one working key.
A receiver demodulates the encrypted RF transmission and recovers the fixed code and rolling code. Upon comparison of the fixed and rolling codes with stored codes and seeing that they pass a set of algorithmic checks, a signal is generated to actuate an electric motor to open or close a movable component.
In addition to the vehicle title, lenders often also require the borrower to provide a set of keys for the car and/or purchase a roadside service plan. Car title loans frequently involve high interest rates, a short time to repay the loan (often 30 days), and a loan amount less than the car's monetary worth. The borrower also risks losing the ...
See traffic encryption key. symmetric key - a key that is used both to encrypt and decrypt a message. Symmetric keys are typically used with a cipher and must be kept secret to maintain confidentiality. traffic encryption key (TEK)/data encryption key (DEK) - a symmetric key that is used to encrypt messages. TEKs are typically changed ...
This key is used to encipher a 40-bit challenge issued by the reader, producing a 40-bit ciphertext, which is then truncated to produce a 24-bit response transmitted back to the reader. Verifiers (who also possess the encryption key) verify this challenge by computing the expected result and comparing it to the tag response.
Automotive security refers to the branch of computer security focused on the cyber risks related to the automotive context. The increasingly high number of ECUs in vehicles and, alongside, the implementation of multiple different means of communication from and towards the vehicle in a remote and wireless manner led to the necessity of a branch of cybersecurity dedicated to the threats ...
Public key transport keys are the public keys of asymmetric key pairs that are used to encrypt keys using a public key algorithm. These keys are used to establish keys (e.g., key wrapping keys, data encryption keys or MAC keys) and, optionally, other keying material (e.g., Initialization Vectors). Symmetric key agreement key
