User registration phase. Registration requires: - a Google account for the Android1 version or an Apple2 account for the iOS version in order to download the application on the online application purchase platform and benefit from updates, - The business email address of the user of the mobile device to be audited. In the event of termination of the Agreement for any of the reasons set forth in this Agreement, TEHTRIS will terminate the entire TEHTRIS Service. This phase will result in the destruction of the Data in accordance with the Article - Reversibility.
User registration phase. The registration process is between the GWN and U is as follows:
User registration phase. A vehicle user needs to register from ESP for getting the recharging services. Its registration procedure is given below:
User registration phase. When a user Ui wishes to register with CS, Ui selects desired identity IDi and password Pi to enter his/her IoT-enabled device such as a card reader. Then, the device collects Ui’s biometric Bi and generates a random number b to com- pute PIDi = h (IDi ǁ b), Ai = Pi ⊕ h (Bi) and Ωi = b ⊕ Ai. Next, it sends (IDi, PIDi, Ai) to CS in a secure channel. After receiving the message, CS ver- ifies the authenticity of the user’s identity IDi. If IDi is illegal, CS rejects Ui’s registration. Otherwise, CS calculates Ci = h (PIDi ǁ Ai), Di = h (PIDi ǁ x) and Ei = Di ⊕ Ai. Then, CS writes the data (Ci, Ei, h (·) ) to a smart card and delivers it to Ui through private communication. When obtains the smart card, Ui inserts it to IoT-enabled device and inputs IDi and Pi to the device again. Then, the de- vice writes Ωi to the smart card. Finally, the smart card records the informations (Ci, Ωi, Ei, h (·) ).
User registration phase. In this phase, a user gets pre-registered with any of its associated authorized server Sy employing a secure channel, using Chebyshev chaotic map-based multi-server to server architecture [42]. After a successful registration the user establishes a shared password PWU with Sy, which is stored by Sy in its repository ℛ against IDU. Next, the former may establish a secure session key with any new server Sx (already authorized from and registered with Sy), by employing a login and authentication phase as described in the next section.
User registration phase. In this phase, a user gets registered with Sy by adopting the following steps.
User registration phase. 1) Ui computes Mi = h(IDi||PWi), Ni = Mi ⊕ h(Bi), and sends Ni, h(Bi) to S via a secure channel.
User registration phase. Fig.4 illustrates the user registration phase. The steps are performed as follows. { || }
User registration phase. A patient needs to register in MRS with the following steps if he wants to get remote medical services: Ru1 chooses his/her , and a random number , gets personal biometric data , and computes biometric key by , . Then, Ru2 On receiving the registration message from Ui, MRS computes , , where , where is reserved space to increase the number of servers in the future. Stores in smart card, where is the error -tolerance threshold of fuzzy extractor. Then, Smart card; Ru3 Ui computes ei = h(IDi || σ i ) ⊕ Ri , fi = h(IDi || RPWi || σi ) . Finally {{IDS , Aj , Xx }, x xx , xx ,x i , Gen(⋅), Rep(⋅), h(⋅),t} are stored in Ui's smart card
