Development of secure data communication channel for mobile environments

Cryptology is the branch of science that contains the information security. It is the general name of the encryption issues used for making the data unreadable before sending it to the transmission medium and translating it into readable form again after reaching the other side. Data security algorithms are in the foreground in the areas which have high level of data security. In this study, transfering and encryption of datas which were leaved and received from the transmission medium by encryption algorithms were ensured in order to provide secure communications on mobile platforms through web services. Encryption and decryption operations were applied on transmitted data with RSA[1] and Elliptic Curve Cryptography [2] which are two asymmetric encryption systems and the comparisons were made. The information obtained by the analysis, it was expressed that elliptic curve cryptosystem provides safer and more sophisticated encryption with smaller key sizes compared to the RSA cryptosystem on mobile platforms. A result of the comparison of key generation, encryption, decryption, encrypted message transmission times, it was stated that encryption, decryption and transmission times with Elliptic curve system which has smaller key sizes lasted shorter than RSA system. In the selection of the right algorithm and key sizes, it was stated that what the advantages and disadvantages of structures were according to each other.
