Abstract: A privacy and authentication protocol (PAP) requires a tag to perform four simple operations in mobile communications: comparing two numbers used to execute a hash function, storing and retrieving a number in users' memory banks, and flipping a bit. In this paper, we will propose an improved PAP which is well secured and efficient in a small amount of computations and is also capable of dealing with both privacy and authentication.
