ABSTRACT:
A method for offloading encryption and decryption of a message received at a message server to one or more end devices that are remote from the message server. An encrypting end device remote from the message server encrypts a message using cryptographic context and transmits the cryptographic context and encrypted message to the message server for storage at the message server. The message server stores the encrypted message as received without decrypting the message. The message server sends the stored cryptographic context and the encrypted message to a decrypting end device in response to the decrypting end device sending a request for the message server to transmit the encrypted message to the decrypting end device. The decrypting end device uses the cryptographic context to decrypt the encrypted message and then presents the decrypted message to a user of the decrypting end device.
