Upon the problems mentioned above, this paper focuses on the following work:? Analyzes the advantages and disadvantages for the key researches both in and abroad;? Studies some existing international standards and protocols including SET and ASC X9;? Gives the designing rules for the secure scheme then proposes a general simple model for mobile payment;? A secure scheme called SeMo is designed according to the different security needs for lineate links and wireless ones;? Analyzes the security for the scheme still basing on the two distinct links, which improves the scheme fully fulfilling the security requirements such as: authentication, integrity, confidentiality and non-repudiation.
