Email Confidentiality

Today's enterprises rely heavily on email systems for their day-to-day business and operations. Statistics show email volume grows at an annual rate of 30% [IDC quoted in Storage Magazine, Oct. 2002] Majority if not all corporations and enterprises rely heavily on emails in their daily business and processes. Private instructions, sensitive information and confidential data are sent over the Internet reaching customers or business partners without protection. A major problem is data confidentiality, unauthorized parties can get access to these sensitive corporate data easily. Encryption refers to the process of turning meaningful information into meaningless garbage. This turning-gold-into-rust process disallows trespassers and unauthorized parties to obtain the confidential and secret information. To information owner, as s/he has the decryption key in hand, s/he can easily execute the rust-to-gold process and reclaim the original secret information.
