Abstract

See full text

A hybrid encryption method for securely transferring an electronic data package from a sender to a plurality of clients. The method comprises storing a shared symmetric key on each of the clients. The sender encrypts a private key of an asymmetric key pair using the shared symmetric key. The sender encrypts the data package with a temporary symmetric key to generate an encrypted data package. The sender encrypts the temporary symmetric key with the public key of the asymmetric key pair to generate an encrypted temporary symmetric key. The sender transmits the encrypted data package, the encrypted temporary symmetric key, and the encrypted private key to the clients. Each client decrypts the encrypted data package by: using the shared symmetric key to decrypt the encrypted private key; using the decrypted private key to decrypt the encrypted temporary symmetric key, and using the decrypted temporary symmetric key to decrypt the encrypted data package.
