Rapid technological advancements in computing have led to the invention of more and more computer products. Universal serial bus (USB) is a popular standard that has been widely adopted in storage devices. USB has become an important component in current computer-connected devices due to its convenience and ease of connectivity. USB has the advantages of high data processing speed, plug-and-play, hot swapping and self-power supplying to peripherals. USB connections allow a wide range of different electronic devices to connect to computers, including keyboards, cell phones, chargers, speakers, printers and various electronic devices. Information security is currently a very important topic in computing. Traditional authentication methods based …show more content…
Third, the staff can steal data from the computers using the USB. These problems pose a serious threat to USB security in a business environment. To solve the above-mentioned problems, we need a more secure authentication protocol for USB storage devices. Most early authentication protocols are password-based. These protocols are relatively easy to implement, but they have many weaknesses. For example, dictionary attacks can crack and steal passwords in a short time. Owing to these problems, the users need a more secure authentication protocol like user password and USB device authentication. The password authentication based on smart cards is also called two-factor authentication [2], meaning that the users must own the smart card to certify the passwords. The smart card-based password authentication provides stronger security guarantees than the earlier password-based authentication. However, this authentication method is problematic if the two factors are compromised; the attacker can successfully obtain the password and any user data stored in the smart card. Three-factor authentication can help avoid this problem and enhance system
