Abstract EN:

The specificity of the information and communication technologies has called for the creation of its own set of rules The French legislator, contrarily to the Egyptian, adopted some legal rules whose goal is to envelope the new technologies of information and communication in order to accentuate the confidence in the numeric economy. The objective of this study is to search, by means of the law, an establishment of a considerable level of security to the on line payment in electronic commerce. Thus, the first part is dedicated to the security of the instruments used in the on line payment in the electronic commerce. These instruments can be classified as classic instrument (the bank card) and revolutionary instruments (the electronic money). In the second part, we are interested by the security of the on line payment operation. Considering the internationalisation of the Internet network, the determination of the applicable law to the payment operation is a decisive element for the establishment of the legal security of this operation in the electronic commerce. In addition, the Internet network is world wide opened, which necessitates the utilisation of the electronic signatures as well as the cryptography in order to establish the determinative effect of documents exchanged during transactions, preserve the confidentiality of these exchanges, assure the identification of the parties and guarantee the non- repudiation of the electronic exchange.
