Problems solved by technology

However, this solution has many disadvantages
[0009] Defect 1: The user should apply for a certificate from the certification authority
These procedures are not very complicated, but in the current society, for an ordinary person, the concept of certification is still very vague, unless there is an urgent need, it is not enough to motivate him to complete those procedures to obtain a certificate
[0010] Flaw 2: A certificate has a double key, which is used by using a common algorithm called RSA
[0012] The third defect of the existing technology is related to the second defect. The telecom operator provides its users with a special method using the RSA algorithm, but it may not necessarily be able to obtain the corresponding return on investment.

Embodiment Construction

[0036] FIG. 1 shows a telephone 101 connected to a telecommunications network 102 . In this example, the terminal that can be used to receive or generate information related to the nature of a transaction is a mobile phone. In practice, it can be any device used to establish a connection with a telecommunications network. Similarly, the 102 network can be regarded as a GSM network, but it can also be any type of network in the existing network, such as DCS, PCS, GPRS, or a future network, such as UMTS.

[0037] Thereby, the phone 101 establishes an RF connection 103 with the network 102 . The connection is established by means of the antenna 104 of the telephone 101 . The antenna 104 is connected to the GSM circuit 105 . The circuit 105 plays the role of modulating and demodulating the signal. First, it demodulates the signal received from the network 102 via the antenna 104 to produce a digital signal. Next, the circuit 105 generates an analog signal from the digital sig...

Abstract

The electronic signature process defines a transaction, and produces a signature for authentication. A message is transmitted with the signature, and received by the server. The server receives the message and verified signature validity producing a second transaction providing an operator over signature. A second message is then sent to the server with the transaction section and the signature with overwriting.

Description

technical field [0001] The object of the present invention is an electronic signature method. According to the understanding of European and French statutes, the invention belongs to the field of electronic signatures. The invention also belongs to the field of transactions between users of a telecommunication network and service providers providing services using said telecommunication network. Background technique [0002] In the trading world, the most common transactions are those involving buying and selling. However, we can still think of a transaction as an act corresponding to sending information to a counterparty who is responsible for confirming that the information sent to him has not been damaged by fraud. It is also possible to consider the use of the invention in the framework field of access control, in which case the transaction will be realized through access authorization requests. For simplicity, the invention will be described in the context of a purch...
