Secret-key generation Sample Clauses

Secret-key generation. We now appropriately bound each term in (33). First note that since the sequence un is uniformly distributed among the set of all possible codeword sequences, it follows that n • The decoder upon observing yr finds a sequence un r jointly typical with y n. 1 H(un) = log2 |C| • Both encoder and the decoder declare the bin-index of un to be the secret-key.

Secret-key generation e wkck e ′ We can now estimate I(Qk; Re ) in (11) by replacing the = gk − ek,2 + 1 + w2c ek,1 = gk − ek,2 + ek,1, (22) ▇ ▇ ▇ where (a) is due to the fact that the conditional mean value true value of gk with its estimate, gˆk derived in the previous subsection. Let us denote the estimate of I(Qk; Re ) based on e whch √ζh gˆe by I(Qk; Rˆe ) with which the length of secret key is now of gk for given gk and ζk is 1+w2 c ( c M − gk) as shown k k in Appendix D, and e adaptively determined as +

Secret-key generation. Pr(ΓA ƒ= Γ [ ΓB Γ) ≤ δ(ε). (164) Our analysis thus far has established the existence of a codebook C˜⊗ that generates a common tuple of sequences .ΣuKΣ, Σy¯K Σ , Σy¯K Σ Σ , satisfies the equivocation constraint (136) and the reliability constraint (164). We next discuss how one can use the codebook C˜⊗ to generate a common secret-key at the two terminals. We consider transmission over a total of M macro-blocks. Each macro-block i spans K coherence blocks the terminals sample sequences ¯xK(i) and ¯xK(i) in an i.i.d. fashion, independently from the previous blocks. Thereafter we execute the steps discussed in the previous sections, which results in the following observations at the legitimate receivers and the eavesdropper: ΓA(i) = .ΣuˆK(i)Σ , ΣyK (i) Σ , ΣyˆK (i) Σ Σ (165)

Secret-key generation. The control unit runs SKeyGen algorithm to generate secret keys for communicating bio-sensors. It takes cer- tificate Certr, certificate Certs, public key g1 and master key g2 as inputs, and outputs secret key pairs SKs and SKr. For the sender, the control unit selects a random number s ∈ Zp, computes SKs and sends it to the sender. SKs = {SKs1, SKs2} = {g2 · hs·Certs , gs} (9) For the receiver, it selects a random number r Zp, computes SKr and sends it to the receiver. r·Certr rSKr = {SKr1, SKr2} = {g2 · h , g } (10) It is important to note that secret key pairs SKs can only be known by the sender and the control unit, and SKr can only be known by the receiver and the control unit.

  • Technology Access Contractor expressly acknowledges that state funds may not be expended in connection with the purchase of an automated information system unless that system meets certain statutory requirements relating to accessibility by persons with visual impairments. Accordingly, Contractor represents and warrants to System Agency that the technology provided to System Agency for purchase (if applicable under this Contract or any related Solicitation) is capable, either by virtue of features included within the technology or because it is readily adaptable by use with other technology, of: • providing equivalent access for effective use by both visual and non-visual means; • presenting information, including prompts used for interactive communications, in formats intended for non-visual use; and • being integrated into networks for obtaining, retrieving, and disseminating information used by individuals who are not blind or visually impaired. For purposes of this Section, the phrase “equivalent access” means a substantially similar ability to communicate with or make use of the technology, either directly by features incorporated within the technology or by other reasonable means such as assistive devices or services which would constitute reasonable accommodations under the Americans With Disabilities Act or similar state or federal laws. Examples of methods by which equivalent access may be provided include, but are not limited to, keyboard alternatives to mouse commands and other means of navigating graphical displays, and customizable display appearance. In accordance with Section 2157.005 of the Texas Government Code, the Technology Access Clause contract provision remains in effect for any contract entered into before September 1, 2006.

  • Infrastructure Vulnerability Scanning Supplier will scan its internal environments (e.g., servers, network devices, etc.) related to Deliverables monthly and external environments related to Deliverables weekly. Supplier will have a defined process to address any findings but will ensure that any high-risk vulnerabilities are addressed within 30 days.

  • COVID-19 Vaccine Passports Pursuant to Texas Health and Safety Code, Section 161.0085(c), Contractor certifies that it does not require its customers to provide any documentation certifying the customer’s COVID-19 vaccination or post-transmission recovery on entry to, to gain access to, or to receive service from the Contractor’s business. Contractor acknowledges that such a vaccine or recovery requirement would make Contractor ineligible for a state-funded contract.

  • Telemedicine Services This plan covers clinically appropriate telemedicine services when the service is provided via remote access through an on-line service or other interactive audio and video telecommunications system in accordance with R.I.
