Higher-order threshold implementations
Web18 de ago. de 2024 · Specifically, it is formally shown how a bounded-query variant of robust probing security can be reduced to the linear cryptanalysis of masked ciphers. As a result, the compositional issues of higher-order threshold implementations can be overcome without relying on fresh randomness. WebWe point out a higher-order weakness in higher-order Threshold Implementations, suggest a mitigation and provide new sharings that use a lower number of input shares.
