2. Create or cite a public/private key encryption algorithm that allows one to encrypt a message so that it may then be received and decoded by n other known recipients. That is, given the public keys of the recipients, p_1, p_2, ... p_n, and a plain text, P, create a cipher text C such that P can be recovered from C if at least one of the private keys, k_1, k_2, ... k_n, are known.
