Origin Authentication of Digitally Signed Message Using Joint Signature Scheme in Mobile Commerce
In this era of advanced technology, mobile commerce has become popular due to rapid growth of communication technology but this requires maintaining secure communication and protection from threats. In this paper, the authors presented a mechanism for secure and authentic communication in mobile commerce based on joint signature scheme. They formulate this technique for the authentication of message originator who signs the message to buy a product online through its mobile operator. Proposed technique is efficient in mobile domain because it is less computative and can be used with limited resources in mobile commerce. An experimental analysis shows that proposed technique overcomes the major drawbacks of traditional digital signed message, such as computational load, communication load, complexity, public key operations, transaction, etc.
