STR Protocol Clause Samples

STR Protocol. STR is basically an “extreme” version of TGDH, where the key tree structure is completely imbalanced or stretched out. This protocol and its features are described in details (▇▇▇▇▇ et al.,1998; ▇▇▇ et al, 2001). Like TGDH, the STR protocol uses a tree structure that associates the leaves with individual random session contributions of the group members. Every internal (non-leaf) node has an associated secret key and a public blinded key. The secret key is the result of a ▇▇▇▇▇▇-▇▇▇▇▇▇▇ key agreement between the node’s two children. The group key is the key associated with the root node. ▇▇▇ uses a key tree to manage the key group. The tree has two types of nodes, namely leaf and internal nodes. Each specific group member Mi is associated with a leaf node LNi, while an internal node INi has two children: the left child INi−1, and the right child LNi. Each leaf node LNi generates randomly a session random si which should be kept secretly, and computes the corresponding blinded session random bri = gsi. An internal node INi has a secret key ki and the corresponding public blinded key bki = gki. The difference is that ki is not randomly chosen, but the result of a two-party DH key exchange between its two children: (2.1) The internal node with the greatest index is considered to be the root. The secret key of the root is the shared group key. For a group of n members, the root is INn, and the group key kn can be recursively computed using Equation 2.1. If n = 4, its group key is K = gs4∙gs3∙gs2s1 mod p. Looking at the STR key tree with n members in Figure 2.10, the member Mc, 1 ≤ i ≤ n, must know its own session random, all blinded keys and blinded session random, and keys of the path from its parent node to root node. More formally, it must store sc, bri, bki for i = 1, · · · , n (br1 = bk1), and ki for i = c, · · · , n. The rest of this section describes how STR deals with the group operations INn kn-1, bkn-1 sn, brn LNn/Mn IN2 k2, bk2 s1/k1, br1/bk1 s2, br2 sn-1, brn-1 LNn-1/Mn-1 LN1/M1 LN2/M2

  • Protocol The attached Protocol shall be an integral part of this Agreement.

  • Signaling protocol 4.1.3.1 SS7 Signaling is AT&T-21STATE’s preferred method for signaling. Where MF signaling is currently used, the Parties agree to use their best efforts to convert to SS7. If SS7 services are provided by AT&T-21STATE, they will be provided in accordance with the provisions of the applicable access tariffs. 4.1.3.2 Where MF signaling is currently used, the Parties agree to interconnect their networks using MF or dual tone MF (DTMF) signaling, subject to availability at the End Office Switch or Tandem Switch at which Interconnection occurs. The Parties acknowledge that the use of MF signaling may not be optimal. AT&T-21STATE will not be responsible for correcting any undesirable characteristics, service problems or performance problems that are associated with MF/SS7 inter-working or the signaling protocol required for Interconnection with CLEC employing MF signaling.

  • Review Protocol A narrative description of how the Claims Review was conducted and what was evaluated.

  • Proposed Policies and Procedures Regarding New Online Content and Functionality By February 1, 2017, the Division will submit to OCR for its review and approval proposed policies and procedures (“the Plan for New Content”) to ensure that all new, newly-added, or modified online content and functionality will be accessible to people with disabilities as measured by conformance to the Benchmarks for Measuring Accessibility set forth above, except where doing so would impose a fundamental alteration or undue burden. a) When fundamental alteration or undue burden defenses apply, the Plan for New Content will require the Division to provide equally effective alternative access. The Plan for New Content will require the Division, in providing equally effective alternate access, to take any actions that do not result in a fundamental alteration or undue financial and administrative burdens, but nevertheless ensure that, to the maximum extent possible, individuals with disabilities receive the same benefits or services as their nondisabled peers. To provide equally effective alternate access, alternatives are not required to produce the identical result or level of achievement for persons with and without disabilities, but must afford persons with disabilities equal opportunity to obtain the same result, to gain the same benefit, or to reach the same level of achievement, in the most integrated setting appropriate to the person’s needs. b) The Plan for New Content must include sufficient quality assurance procedures, backed by adequate personnel and financial resources, for full implementation. This provision also applies to the Division online content and functionality developed by, maintained by, or offered through a third-party vendor or by using open sources. c) Within thirty (30) days of receiving OCR’s approval of the Plan for New Content, the Division will officially adopt and fully implement the amended policies and procedures.

  • Protocols Each party hereby agrees that the inclusion of additional protocols may be required to make this Agreement specific. All such protocols shall be negotiated, determined and agreed upon by both parties hereto.
