Today's News Authentica Inc has released email and web page security software that enables users to protect information even when they release it over the internet. WebVault and MailVault encrypt sections of a document with a different algorithm, whether for web page or email, logging the encryption key as well as the access privileges associated with the document on a centralized server. By combining the key with the client software downloaded from the web, users can regulate access, stop downloads or copying, and find out who is looking at what.
Users can also destroy all emails by destroying the key on the server.
Because there is no key sent with the document, old email or messages sent to employees who leave the company cannot be read because the keys were based somewhere else and have been wiped. Authentica uses the 128-bit RC4 encryption key from RSA, the key which Bruce Schneier, cryptanalyst and CTO of Counterpane Internet Security Inc has said would take trillions of dollars and a trillion years to crack. Authentica is aiming the software at the B2B supply chain sector where it could be used for sending out tenders to subcontractors and then canceling the details for the firms which didn't win the commission. It will also work for firms writing and selling reports. The authentication policy could be configured to allow users to read the reports for a designated time.
