Communications giant BT has launched two managed security services.
BT Secure Mail and Encrypted Message Exchange (BT EMX) are based on a public key infrastructure (PKI).
In a PKI, user identity is bound to a public key by means of a digital certificate. Communications can then be encrypted with a public key and decrypted with a private key. A certificate authority acts as a trusted third party to validate user credentials and link them to a public key. In this instance, BT will act as the certificate authority.
The services are aimed at regulated industries such as the financial sector, government and healthcare. Email messages can be encrypted to be sent over the internet.
The new messaging security services will run on LogicaCMG's application services provider platform, and will be powered by Echoworx, a software security company.
