An authentication compiler Sample Clauses

An authentication compiler clause defines the requirements and procedures for verifying the identity of parties involved in a transaction or agreement. Typically, this clause outlines the methods or technologies that must be used to authenticate users, such as digital signatures, multi-factor authentication, or secure tokens, and may specify the standards or protocols to be followed. By establishing clear authentication processes, the clause helps prevent unauthorized access and ensures that only legitimate parties can participate, thereby reducing the risk of fraud or security breaches.
An authentication compiler. In [6], ▇▇▇▇ et al. introduced a scalable compiler which transforms any GKA protocol P , secure against passive adversary, to an authenticated GKA protocol P ′, secure against an active adversary. It achieves this by enhancing the protocol to include a (pre-)round where everyone broad- casts its identity and a random nonce. Thereafter each mes- sage is accompanied by a signature on the message, identi- ties of the participants and their nonces (see [6] for details). Then if P is a secure GKA protocol, then the protocol P ′ is a secure Authenticated GKA protocol. Namely, where: qex and qs are the number of Execute and Send queries respectively. ' |P| t′ = t + ( qex + qs).tP ' , tP ' is the time to execute P ′. AdvPA' (t, qex, qs): Advantage of an active adversary ( ′) against the authenticated protocol P ′, making qex Execute queries and qs Send queries in time t. AdvPA(t′, 1): Advantage of a passive adversary ( ) against the protocol P , making 1 Execute query in time t′. A AdvPA(t, qex): Advantage of a passive adversary ( ) against the protocol P , making qex Execute queries in time t′. SuccDDH(t′): Success probability of an adversary against an instance of the DDH problem in time t′. SuccΣ(t′): Success probability of an adversary against the signature scheme Σ in time t′. and k is the security parameter.

  • An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee and to the Company. The Trustee may at any time terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the Company. Upon receiving such a notice of resignation or upon such a termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating Agent which shall be acceptable to the Company and shall mail written notice of such appointment by first-class mail, postage prepaid, to all Holders of Securities of the series with respect to which such Authenticating Agent will serve, as their names and addresses appear in the Security Register. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section. The Company agrees to pay to each Authenticating Agent from time to time reasonable compensation as negotiated between the Company and such Authenticating Agent for its services under this Section. If an appointment with respect to one or more series is made pursuant to this Section, the Securities of such series may have endorsed thereon, in addition to the Trustee's certificate of authentication, an alternate certificate of authentication in the following form: Form of Authenticating Agent's Certificate of Authentication Dated:_________________ This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture. -------------------------- As Trustee By ________________________ As Authenticating Agent By ________________________ Authorized Signatory

  • Certificate of Authentication Only such Securities as shall bear thereon a certificate of authentication substantially in the form hereinbefore recited, executed by the Trustee by the manual signature of one of its authorized officers, shall be entitled to the benefits of this Indenture or be valid or obligatory for any purpose. The execution of such certificate by the Trustee upon any Security executed by the Issuer shall be conclusive evidence that the Security so authenticated has been duly authenticated and delivered hereunder and that the Holder is entitled to the benefits of this Indenture.

  • Execution, Authentication and Delivery The Notes shall be executed on behalf of the Issuer by any of its Authorized Officers. The signature of any such Authorized Officer on the Notes may be manual or facsimile. Notes bearing the manual or facsimile signature of individuals who were at any time Authorized Officers of the Issuer shall bind the Issuer, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Notes or did not hold such offices at the date of such Notes. The Indenture Trustee shall upon Issuer Order authenticate and deliver the Class [A-1] Notes for original issue in an aggregate principal amount of $[__________], the Class [A-2] Notes for original issue in an aggregate principal amount of $[__________], the Class [A-3] Notes for original issue in an aggregate principal amount of $[__________] and the Class [A-4] Notes for original issue in an aggregate principal amount of $[__________]. The aggregate principal amount of the Class [A-1] Notes, the Class [A-2] Notes, the Class [A-3] Notes and the Class [A-4] Notes outstanding at any time may not exceed such respective amounts except as provided in Section 2.05. The Notes shall be issuable as registered Notes in minimum denominations of $1,000; [provided, however, that any Retained Notes retained by the Sponsor or the Seller or conveyed to any of their respective Affiliates shall be issued as Definitive Notes and the holder of such Retained Notes shall be a Note Owner and a Noteholder for all purposes of this Indenture, except as otherwise specified in the Basic Documents]. Each Note shall be dated the date of its authentication. No Note shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose, unless there appears on such Note a certificate of authentication substantially in the form included in Exhibit A, executed by the Indenture Trustee by the manual or facsimile signature of one of its authorized signatories, and such certificate upon any Note shall be conclusive evidence, and the only evidence, that such Note has been duly authenticated and delivered hereunder.

  • Authentication Date The Notes of this Series shall be dated the date of their authentication.

  • Multi-Factor Authentication for Remote Access DST shall use multi factor authentication and a secure tunnel, or another strong authentication mechanism, when remotely accessing DST’s internal network.
