WebWe consider Shamir’s secret-sharing scheme among n= 2 parties with recon-struction threshold k= 2 over the prime fieldF of order p⩾ 3. The secret-sharing scheme is the Massey secret-sharing scheme [24] corresponding to the (punctured) Reed-Solomon code with evaluation places (0,α 1,α 2). That is, the WebApr 2, 2024 · Background: Logistic regression (LR) is a widely used classification method for modeling binary outcomes in many medical data classification tasks. Researchers that collect and combine datasets from various data custodians and jurisdictions can greatly benefit from the increased statistical power to support their analysis goals. WebD chooses a private lattice Basis B and selects linearly independent binary vectors λi of lengthn and weightm > 1. Then he computes the secret shares ci = B· λi and secretly forwards them to the participants. 2. Upon receipt of the own secret share, each participant P checks the hash value, in particular he verifies whether the hash value ... chrome pdf 转 图片
