Encryption using N number of keys (PKI) and decryption using M out of N Keys

rs flag

On a tendering portal, I want to encrypt the value of the submission using N number of public keys (PKI) and later on want to decrypt the same information using M out of N number of private keys (PKI). M<N and sequence of decryption should not matter. Please suggest the algorithm for doing so.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
