Design and Implementation of OTP Base on MD5

Abstract

Encryption of information is getting increasingly large attention, due to the popularity of internet and the advance of technology. One of the encryption algorithms, MD5, is commonly used in data encryption nowadays. In this paper, MD5 algorithm was briefly described and used to construct a dynamic password encryption technique with time parameters. This dynamic password has no internal relevance, which means the new password can not be derived using previous passwords. Generation of password also takes a relative short time frame, such that in theory the encryption system can not be breached.
