Experimental Study of Message Digests on Mobile Hand Held Devices

Due to the continuous advancement in technology, mobile devices are playing important role in everyone’s day to day life. Security is the one of the biggest concern in different type of networks. Due to diversify nature of network, security breaching became a common issue in different form of networks. Solutions for network security comes with concepts like cryptography in which distribution of keys have been done. If you want to send data to some other persons through network then if you truly want some sort of key that you and he can use to encode/decode messages. But you don’t want to keep using the same key, or you will make it easier and easier for others to crack your cipher. So, Cryptogr valuable tool in cryptography. They are applied in many areas of information security to provide protection of the authenticity of messages; data integrity verification which prevents modification of data from going undetected, t stamping and digital signature scheme This paper presents a implementation and evaluation of message digest for mobile devices. This message digest system takes into account the device limitations and thus generates a functional digital signature.
