A Survey of Latest Trends in Cryptography and Elliptic Curve Cryptography

With the advances in  electronic technology  today there is a lot of progress  in computing power  and also the parallelism in processors . These advances have made cryptographic solutions to  security  more complicated specially in the case of electronic transactions. There are many cryptographic techniques which have their own advantages and characteristics. There are basically two types of cryptosystems .symmetric and asymmetric. Some of them make use of small key.  This paper gives survey of all such systems and  also  the comparative study of them with elliptic curve cryptography.
