Mutual Authentication Phase Sample Clauses

Mutual Authentication Phase. In this phase, GNi first sends a message to its right neighbor GNi+1, and GNi+1 will authenticate GNi. At the same time, GNi will also receive a message from its left neighbor GNi−1, and it needs to authenticate GNi−1. Figure 3 shows the mutual authentication phase and the group key generation phase of our protocol. XXx performs the following operations.

Mutual Authentication Phase. As a precondition, HA needs to pre-share a distinct sym- metric key kF H with each FA. When a user MN visits a new foreign network, the following steps are performed:

Mutual Authentication Phase. By our design, a set of leaders are included among members to represent the group to the core network. In order to avoid collisions as a result of multiple initiations at the same time, leaders are instructed to wait for a random amount of time before they can send the first message. If any leaders hears the first message sent by another leader the hearing leader postpones sending until the current procedure is complete with success. The chosen leader and the HSS authenticate mutually as shown in Fig. 2. The leader sends the second message including their own identity, members’ identity [𝐼𝑀𝑆𝐼]𝑖 and group identity 𝐼𝑀𝐺𝐼 to the Mobility Management Entity (MME), where 1≤ 𝑖 ≤ 𝑛. The MME adds its own identity 𝑆𝑁 − 𝐼𝐷 and passes to the HSS. The HSS checks the third message first. Next, it generates a random number 𝑅𝐴𝑁𝐷 and sequence number 𝑆𝑄𝑁 and computes three parameters: authentication vector 𝐴𝑉, group information 𝐺𝐼𝑛𝑓𝑜 and group leader key 𝐺𝐿𝐾 . Then, it includes three parameters in the fourth message and sends to the MME. The MME sends the fifth message to the MTC devices via a broadcast channel in the LTE downlink channel.

  • Access by and Authentication of Authorized Users Authorized Users of the Participating Institutions shall be granted access to the Licensed Materials pursuant to the following:

  • Execution and Authentication At least one Officer must sign the Notes for the Company by manual or facsimile signature.

The Trustee will, upon receipt of a written order of the Company signed by an Officer (an “Authentication Order”), authenticate Notes for original issue that may be validly issued under this Indenture, including any Additional Notes. The aggregate principal amount of Notes outstanding at any time may not exceed the aggregate principal amount of Notes authorized for issuance by the Company pursuant to one or more Authentication Orders, except as provided in Section 2.07 hereof. The Trustee may appoint an authenticating agent acceptable to the Company to authenticate Notes. An authenticating agent may authenticate Notes whenever the Trustee may do so.
