ABSTRACT
Mobile phones are most common way of communication and accessing Internet based services. Sending and receiving sensitive data are not only used for proper communication at mobile phones. However, the security of mobile communication has topped the list of concerns for mobile phone users. So Public key cryptography is effective security solution to provide secure the mobile communications. In this paper provides a ECC module to secure data encryption and decryption using public key cryptography. The form of key exchange, communication privacy through encryption, authentication of sender and digital signature to ensure message integrity are implementation of ECC module.
