Abstract:
A method and apparatus, such as a secure distribution server, receives encrypted information from a sender, wherein the encrypted information is for transmission to a plurality of intended recipients. In addition to the encrypted information, the method includes receiving an encrypted secret key that is encrypted using a public key associated with the secure distribution server. The method and apparatus decrypts the encrypted secret key to produce a decrypted secret key. The method and apparatus then encrypts the decrypted secret key with the corresponding public key of at least one (or each of a plurality of) intended recipient(s) to produce at least one (or plurality of) recipient-specific secure secret keys. The method and apparatus then forwards the received encrypted information sent by the sender and also sends at least one recipient-specific secure secret key to a corresponding intended recipient.
