Businesses using secure messaging to protect customer communications often discover that all these problems and their related costs grow exponentially. The corpus of keys changes faster and is far more complex to administer. Unlike employees, customers may have fewer concerns about asking a firm’s IT staff to retrieve or reset a forgotten password, placing a greater burden on support staff. Training large groups of customers to use traditional secure messaging—to recognise digital signatures, decrypt messages, and sign and encrypt their own responses—is also impractical.
What is needed is a secure-messaging solution that requires no action by the end-user. Such a solution would shift the burden of encryption, decryption, and signing and verifying messages—as well as finding and remembering the necessary keys—to an automated system that works invisibly at the network level. For automated secure messaging to be truly effective and used widely, however, it must be based on open standards and must offer some way to set up and maintain secure connections with recipients who do not have secure messaging in place and/or cannot be trained to use a secure-messaging solution.
Solutions must not only be invisible to senders, once recipients have authenticated themselves, the solution must also automate verification and decryption as well as securing and signing any response. To answer this need, systems have now been developed that operate transparently on the network layer and use small-footprint proxies on the recipient end. These systems can provide automated, two-way message security and authentication with no need for user training at either end.
With such systems in place, email and online communications can be transformed from a prime target for cyber criminals into a safe means of communicating with customers and partners while significantly reducing the potential of identity theft.
