Communication Cost Sample Clauses

Communication Cost. We assume C is 256 bits and timestamp T is 64 bits. In the mutual authentication phase of our protocol, each GN needs to send message (SEi+1, Ci, t1i ) to GNi+1 and broadcast (Xi, Yi, Zi, t2i ). Therefore, each GN needs to send messages of length 5C + 2T and receive messages of length (3n 1)C + nT. The total communication cost in the the mutual authentication phase and the group key generation phase of our protocol is (3n2 + 4n)C + (n2 + 2n)T.

Communication Cost. The communication cost is shown in Table 3.1 that compared among STR, braid groups on GDH and this protocol TBG. The number of rounds on TBG is constant in all events same as STR what better than braid groups on GDH protocols on merge event. The number of rounds on merge operation in Braid groups on GDH depends on number of merging members, but all operations in TBG and STR do not depend on number of members that dynamic movement. The number of rounds in TBG is equals to STR and Braid groups on GDH in join, leave and partition protocol. In merge protocol, the number of rounds in TBG is less than Braid groups on GDH which depending on number of merging member.

Communication Cost. In order to examine the overhead communication of the four schemes during the key process for negotiating, we set the p-length to 512-bit and the q- length to 160-bit. Let |G1|, |G2| and |Zq| represent the size of an element in G1, G2 and Z | q, and |H| indicates the duration of the result of the general hash operation. Gq is equivalent to G1 in our system. That is to say, |Gq| = 1024(bits), |G1| = 1024(bits), |G2| = 1024(bits) (bits). |T| denotes the time stamp length. Also supposed to be |T| = 32 (bits). The session sponsoring (the user) side in Xxxxx et al's protocol must transmit the message (xAuthi, Cm, Ri, Bij, Mi, Authij), and the responding side (the server) must send the message (Xxxxxx, Wj , Rj ). XXxxxx, Cm, Xx, Xxx, Mi, Wj, Rj, Rj, Xxxxxx, Authji, all of Z, and all of them. The communication costs for Xxxxx et al. were thus 7|G1| + 2|H| = 7 | 1024 + 2 | 160 = 7488 (bits). The session sponsor (smart metre) side of the protocol of Xxxxx et al. has to transmit the message (T1, C1, A1, A3), and the answering party (server) has to send the message (g2, A2). A1, A2, A3 are the general hash operation outputs. T1, g2 os G2 and C1 os Z os os os os os os os os. Thus, Xxxxx et alcommunication .'s costs is 2|G2|+|Zq|+3|H| = 2 (bits). The session sponsor side (smart card) must send a message in Li et alprotocol .'s and the answering side (server) needs to send the message (Fui, kui, Bui, dtui, t) (Dsj , ksj ). It's the timeline. Dsj, Dui are the general hash operation outputs. Kui, Bui, ksj è on the ground G2 and Fui, dtui è on the ground Z è on the ground. Thus, the cost of communication between Li et al is |T| + 3|G1| + 2|Zq| + 2|H| | 32 + 3 (bits). The sponsor side (a server) must send a message to the system (pidi, μi, Ai, T1 I and the answering side (a server) must send the message (pidj, μj, Aj, T1 j). Pidi and pidj are general hash operation outputs. μi, xx os Z os os q and Ai, Aj os Gq. The timestamps are T 1 I and T 1 j. The cost of our scheme is therefore 2|H|+2|Zq|+2|Gq|+2|Gq|+2|T|=2 kin 160 + 2 kin 1024 + 2 kin 32=2752 (bits).
