There are a lot of ways to keep vehicular communication or communication between vehicles safe. * Next, how long does it take to encrypt and decode a message with each security method?

In public key cryptography, a number of different asymmetric encryption techniques are used.

Most modern encryption uses a binary cipher to protect plaintext. Bit streams have their bits individually encrypted into ciphertext, whereas block streams have their bits grouped into blocks before encryption. This article describes the phases that a modern cryptographic key goes through.

Explain why attacks on a cipher are more difficult for a short message.
