METHOD AND APPARATUS FOR SECURE E-MAIL

摘要

An enterprise-based system includes a storage server equipped to generate a split encryption key having at least a first key portion and a second key portion, that is used by the storage server to encrypt at least a portion of a message. Additionally, the first key portion of the split encryption key is retained by the storage server, while the second key portion of the split encryption key is delivered to a message routing server and is discarded from the storage server. The message routing server in turn provides the second key portion to one or more recipients of the message to facilitate recipient access to the message.
