Key Establishment Sample Clauses

The Key Establishment clause defines the procedures and requirements for generating, exchanging, and managing cryptographic keys between parties in a secure communication or data protection context. Typically, this clause outlines the approved methods for key generation, the protocols for securely exchanging keys (such as using public key infrastructure or secure key exchange algorithms), and the responsibilities of each party in maintaining key confidentiality. Its core practical function is to ensure that all cryptographic operations are based on securely established keys, thereby protecting sensitive information from unauthorized access and mitigating the risk of data breaches.

Key Establishment. Key establishment may be broadly divided into key transport and key agreement. A key transport protocol or mechanism is a key establishment technique where one party creates or otherwise obtains a secret value, and securely transfers it to the other(s). A key agreement protocol or mechanism is a key establishment technique in which a shared secret is derived by two (or more) parties as a function of information contributed by, or associated with, each of these, (ideally) such that no party can predetermine the resulting value. Thus in scenarios, where there is no central authority and the task of key generation cannot be assigned to a single (or few) participant(s)(as is most often the case in ad hoc networks), key agreement is a good alternative to key transport. But more often in a key agreement protocol, it is required that a participating member be assured that no other party aside from a specially identified party (or parties) may gain access to a particular secret key. Such a protocol is known as an authenticated key agreement protocol. It is worth noting here that the term authentication, in this context, means to have the knowledge of the identity of parties who may gain access to the key. To corroborate the fact that the same identities actually participated in the protocol, one has to rely on other mechanisms like entity authentication. Key agreement protocols can be designed using symmetric or asymmetric techniques. To further illustrate the above concepts present the two- party ▇▇▇▇▇▇-▇▇▇▇▇▇▇ key agreement protocol. 2.2.4.1 The ▇▇▇▇▇▇-▇▇▇▇▇▇▇ Key Agreement Developed by ▇▇▇▇▇▇ and ▇▇▇▇▇▇▇, this algorithm allows the establishment of a cryptographic secret key between two entities by means of data exchange through an insecure communication channel. The algorithm executed between two entities A and B is defined as follows: 1) A and B agree on two randomly chosen numbers p and g, so that p is a large prime number and g < p; 2) A chooses a secret random number SA and B chooses a secret random number SB; 3) A computes a public value TA = gSA mod p and B computes a public value TB = gSB mod p; 4) A sends TA to B and B sends TB to A; 5) A computes TBSA mod p = (gSB)SA mod p and B computes TASB mod p = (gSA)SB mod p. Since (gSA)SB mod p = (gSB)SA mod p = K, these two entities share a secret cryptographic key K. In other works, two entities are able to exchange information through a channel that anyone can listen to and at the end of the process the two e...

  • PERMANENT ESTABLISHMENT 1. For the purposes of this Agreement, the term "permanent establishment" means a fixed place of business through which the business of an enterprise is wholly or partly carried on. 2. The term " permanent establishment" includes especially: (a) a place of management; (b) a branch; (c) an office; (d) a factory; (e) a workshop; and (f) a mine, an oil or gas well, a quarry or any other place of extraction of natural resources. 3. The term "permanent establishment" also includes: (a) a building site or construction or assembly or installation project or supervisory activities in connection therewith, but only where such site, project or activities continue for a period or periods aggregating more than 6 months within any twelve-month period; (b) the furnishing of services, including consultancy services, by a resident of a Contracting State through employees or other personnel engaged by the enterprise for a period or periods aggregating more than 183 days within any twelve-month period. 4. Notwithstanding the preceding provisions of this Article, the term "permanent establishment" shall be deemed not to include: (a) the use of facilities solely for the purpose of storage, display or delivery of goods or merchandise belonging to the enterprise; (b) the maintenance of a stock of goods or merchandise belonging to the enterprise solely for the purpose of storage, display or delivery; (c) the maintenance of a stock of goods or merchandise belonging to the enterprise solely for the purpose of processing by another enterprise; (d) the maintenance of a fixed place of business solely for the purpose of purchasing goods or merchandise or of collecting information, for the enterprise; (e) the maintenance of a fixed place of business solely for the purpose of carrying on, for the enterprise, any other activity of a preparatory or auxiliary character; (f) the maintenance of a fixed place of business solely for any combination of activities mentioned in sub-paragraphs (a) to (e), provided that the overall activity of the fixed place of business resulting from this combination is of a preparatory or auxiliary character. 5. Notwithstanding the provisions of paragraphs 1 and 2, where a person -- other than an agent of an independent status to whom paragraph 6 applies -- is acting on behalf of an enterprise and has, and habitually exercises, in a Contracting State an authority to conclude contracts in the name of the enterprise, that enterprise shall be deemed to have a permanent establishment in that State in respect of any activities which that person undertakes for the enterprise, unless the activities of such person are limited to those mentioned in paragraph 4 which, if exercised through a fixed place of business, would not make this fixed place of business a permanent establishment under the provisions of that paragraph. 6. An enterprise shall not be deemed to have a permanent establishment in a Contracting State merely because it carries on business in that State through a broker, general commission agent or any other agent of an independent status, provided that such persons are acting in the ordinary course of their business. 7. The fact that a company which is a resident of a Contracting State controls or is controlled by a company which is a resident of the other Contracting State, or which carries on business in that other State (whether through a permanent establishment or otherwise), shall not of itself constitute either company a permanent establishment of the other.

  • Establishment of Service 6.1 After receiving certification as a local exchange company from the appropriate regulatory agency, <<customer_name>> will provide the appropriate BellSouth service center the necessary documentation to enable BellSouth to establish a master account for <<customer_name>>’s resold services. Such documentation shall include the Application for Master Account, proof of authority to provide telecommunications services, an Operating Company Number ("OCN") assigned by the National Exchange Carriers Association ("NECA") and a tax exemption certificate, if applicable. When necessary deposit requirements are met, as described in Section 6.6 below, BellSouth will begin taking orders for the resale of service. 6.2 Service orders will be in a standard format designated by BellSouth. 6.3 <<customer_name>> shall provide to BellSouth a blanket letter of authorization ("LOA") certifying that <<customer_name>> will have End User authorization prior to viewing the End User's customer service record or switching the End User's service. BellSouth will not require End User confirmation prior to establishing service for <<customer_name>>’s End User customer. <<customer_name>> must, however, be able to demonstrate End User authorization upon request. 6.4 BellSouth will accept a request directly from the End User for conversion of the End User's service from <<customer_name>> to BellSouth or will accept a request from another CLEC for conversion of the End User's service from <<customer_name>> to such other CLEC. Upon completion of the conversion BellSouth will notify <<customer_name>> that such conversion has been completed. 6.5 If BellSouth is informed that an unauthorized change in local service to <<customer_name>> has occurred, BellSouth will reestablish service with the appropriate local service provider and will assess <<customer_name>> as the CLEC initiating the alleged unauthorized change, the unauthorized change charge described in FCC Tariff No. 1, Section 13 or applicable state tariff. Appropriate nonrecurring charges, as set forth in Section A4 of the General Subscriber Service Tariff, will also be assessed to <<customer_name>>. In accordance with FCC Slamming Liability Rules, the relevant governmental agency will determine if an unauthorized change has occurred. Resolution of all relevant issues shall be handled directly with the authorized CLEC and <<customer_name>>. 6.6 BellSouth reserves the right to secure the account with a suitable form of security deposit, unless satisfactory credit has already been established. 6.6.1 Such security deposit shall take the form of cash for cash equivalent, an irrevocable Letter of Credit or other forms of security acceptable to BellSouth. Any such security deposit may be held during the continuance of the service as security for the payment of any and all amounts accruing for the service. 6.6.2 If a security deposit is required, such security deposit shall be made prior to the inauguration of service. 6.6.3 Such security deposit shall be two months' estimated billing. 6.6.4 The fact that a security deposit has been made in no way relieves <<customer_name>> from complying with BellSouth's regulations as to advance payments and the prompt payment of bills on presentation nor does it constitute a waiver or modification of the regular practices of BellSouth providing for the discontinuance of service for non-payment of any sums due BellSouth. 6.6.5 BellSouth reserves the right to increase the security deposit requirements when, in its reasonable judgment, changes in <<customer_name>>'s financial status so warrant and/or gross monthly billing has increased beyond the level initially used to determine the security deposit. 6.6.6 In the event service to <<customer_name>> is terminated due to <<customer_name>>'s default on its account, any security deposits held will be applied to <<customer_name>>'s account. 6.6.7 Interest on a cash or cash equivalent security deposit shall accrue and be paid in accordance with the terms in the appropriate BellSouth tariff.
