Dynamic threshold public-key encryption

WebAug 22, 2024 · 1. Threshold decryption of public-key encryption schemes allows the decryption key to be distributed among trustees. Then, to decrypt the ciphertext it requires at least threshold t trustees to run the decryption protocol in order to get the plain text. Now, most of the literature is either based on generic multiparty computation (which I am ...

WebNov 18, 2024 · Asymmetric encryption. Asymmetric algorithms are usually used to encrypt small amounts of data such as the encryption of a symmetric key and IV. Typically, an individual performing asymmetric encryption uses the public key generated by another party. The RSA class is provided by .NET for this purpose. WebMay 30, 2016 · Dynamic threshold public-key encryption, proposed by Delerablée and Pointcheval (CRYPTO 2008), is an extension of ordinary threshold encryption which enables decryption servers to join the system even after the setup phase, and to choose the authorized set and the threshold of decryption dynamically. binary lifting technique https://zukaylive.com
