Proof of Knowledge Sample Clauses

Proof of Knowledge. Proof of knowledge [11] is an interactive cryptographic mechanism providing compu- tational proof of “knowledge”. This mechanism works between two parties, namely the prover, that wants to prove his knowledge of some secret to a second party, and the verifier, that accepts or rejects the veracity of the published statement. This scheme can also work without the necessity to unravel the secret to the verifier, as in the case of so-called zero-knowledge proof. The two-party proof of knowledge, without the knowledge-error, is built upon two properties: • Completeness that states that if the send statement to the verifier is true, the verifier will always accept the proof, and • Validity that requires that the success probability of knowledge must be at least as high as the success probability of the prover in convincing the verifier, as this property guarantees, that some prover without the knowledge can succeed in convincing the verifier. With the knowledge-error is the validity property replaced with the property soundness, that states, that there is only a small probability of accepting a wrong statement by the verifier [4]. To prove various statements, such as those built on the discrete logarithm prob- lem (also in a specific form), can be verified by using so-called sigma protocols (sometimes marked as the Σ-protocols). These protocols use a three-way challenge- response structure with the first step called the commitment. The prover, to verify some knowledge interact with the verifier as follows:

  • Proof of Illness A Board may request medical confirmation of illness or injury and any restrictions or limitations any Employee may have, confirming the dates of absence and the reason thereof (omitting a diagnosis). Medical confirmation is required to be provided by the Employee for absences of five (5) consecutive working days or longer. The medical confirmation may be required to be provided on a form prescribed by the Board. Where an Employee does not provide medical confirmation as requested, or otherwise declines to participate and/or cooperate in the administration of the Sick Leave Benefit Plan, access to compensation may be suspended or denied. Before access to compensation is denied, discussion will occur between the Union and the school board. Compensation will not be denied for the sole reason that the medical practitioner refuses to provide the required medical information. A school Board may require an independent medical examination to be completed by a medical practitioner qualified in respect of the illness or injury of the Board’s choice at the Board’s expense. In cases where the Employee’s failure to cooperate is the result of a medical condition, the Board shall consider those extenuating circumstances in arriving at a decision.
