Abstract
A network-based method for secure messaging is performed by: receiving a message sent by a sender to a recipient with a store-and-forward protocol, at a network location. The received message is decrypted at the network location with the sender's encryption key. Then the decrypted message is encrypted at the network location with the recipient's encryption key, and forwarded from the network location for delivery to the recipient.
Claims27
A network-based method for secure messaging, comprising:
- receiving, at a network location, a message sent by a sender to a recipient with a store-and-forward protocol;
- decrypting said received message at said network location with said sender's encryption key;
- encrypting said decrypted message at said network location with said recipient's encryption key;
- and
- forwarding said encrypted message from said network location for delivery to said recipient.
A messaging security apparatus, for securing a message sent by a sender to a recipient via a store-and-forward message center on a network, comprising:
- a key database configured for storing respective user encryption keys;
- and
- an encryption unit associated with said key database and said message center, wherein said encryption unit is permitted to obtain user encryption keys from said database, and is configured for decrypting said message with said sender's encryption key, and for encrypting said message with said recipient's encryption key.
A computer-readable storage medium containing a set of instructions for secure messaging, the set of instructions comprising:
- a communication routine, for inputting and outputting messages with a store-and-forward protocol;
- a decryption routine, for decrypting a message utilizing a key associated with a sender of said message;
- and
- an encryption routine, for encrypting a message utilizing a key associated with a recipient of said message.
