Can bus encryption?
The Controller Area Network (CAN) bus security feature is implemented using an intuitive algorithm that encrypts the 8-byte payload data using a symmetric key that is being dynamically changed using synchronized key generators across all nodes.
How does honey encryption work?
Honey encryption is a type of data encryption that “produces a ciphertext, which, when decrypted with an incorrect key as guessed by the attacker, presents a plausible-looking yet incorrect plaintext password or encryption key.”
Can Bus challenges?
CANBUS is a high speed network which requires high quality wiring in order to operate properly. As such, it is sensitive to improper wiring. The majority of CANBUS communication problems are caused by poor wiring, incorrect termination, or the use of multiple frequencies on the same bus.
CAN bus security challenges?
For such applications, the Controller Area Network (CAN) is the most-widely used communication protocol, which still suffers from various security issues because of the lack of encryption and authentication. As a result, any malicious/hijacked node can cause catastrophic accidents and financial loss.
What is biometric encryption?
Biometric EncryptionTM is an algorithm which has been developed to securely link and retrieve a digital key using the interaction of a biometric image, such as a fingerprint, with a secure block of data, known as a BioscryptTM. The key can be used, for example, as an encryption/decryption key.
CAN protocol vulnerabilities?
Although CAN has many security features, it is still vulnerable to the attacks. The main problem with CAN protocol is lack of encryption and authentication. The lack of authentication allows any unauthorised nodes to join the network and take part in the communication.
How are messages encrypted in honey encryption?
Honey encryption protects a set of messages that have some common features (e.g., credit card numbers are such messages). A message set is called a message space. Before encrypting a message, we should determine the possible message space. All messages in the space must be sorted in some order.
Can a wrong key be used in honey encryption?
Honey encryption can also address the previously mentioned vulnerability. Even when a wrong key is used for decryption, the system can yield a valid-looking plaintext message; therefore, the attacker cannot tell whether the guessed key is correct or not.
Which is an innovation of the honey encoder?
The innovation of honey encryption is the design of the distribution-transforming encoder (DTE). According to the probabilities of a message in the message space, it maps the message to a seed range in a seed space, then it randomly selects a seed from the range and XORs it with the key to get the ciphertext.
Is it possible to secure the CAN bus?
MSCSED THESIS: CAN BUS SECURITY protocols such as SSL/TLS without impacting the messages on the CAN bus itself. This thesis does demonstrate that this is possible for a considerable time overhead (compared to the CAN bus message times) but has not been integrated with the cryptographic approaches at this point.
