Detailed explanation-1: -In computer science, cryptography refers to secure information and communication techniques derived from mathematical concepts and a set of rule-based calculations called algorithms, to transform messages in ways that are hard to decipher.
Detailed explanation-2: -The correct statement is-Receiver decrypts the message using their private key.
Detailed explanation-3: -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.
Detailed explanation-4: -Which of the following forms of cryptography is best implemented in hardware? Symmetric stream cryptography is best implemented in hardware because the data size makes it infeasible to have enough RAM or CPU cycles to process the data.
