Many researches have been done in order to improve the security services with encryption and decryption of sensitive . In addition , Security protocols have been developed to protect accessing the data from the authorized users . One of these protocols is the One - Time Password (OTP) authentication in the USB security tokens . A well - known USB security Token is the Yubikey security tokens . However this token has protocol overhead and time consuming in addition to the speed and memory capacity limitations . In this paper , we have proposed a modification to the Yubikey security protocols in order to enhance the overhead , speed and size limitations in the user authentication process , in addition to increase the security factors that depend on a random number generated from the server and sent to the user via e - mail and SMS to his mobile . Experimental results have been conducted using C# programming language for the user and the server side . All the results show the efficiency improvement of our proposed protocol over the Yubikey security token in the terms of authentication factors , speed and memory size .
