In 1984, Adi Shamir, one of the inventors of the well-known RSA public key system, proposed that using identity directly as a public key, rather than relying on certificates, might be the best approach for simplifying public key cryptography. For the next two decades, numerous attempts were made to provide an Identity-Based Encryption algorithm, but no practical solution was found.
In 2000, Dr. Dan Boneh and Dr. Matt Franklin achieved a mathematical breakthrough and invented the first practical Identity-Based Encryption (IBE) system. Their scheme uses bilinear mappings, known as Weil and Tate pairings, on elliptic curves to obtain an algorithm that can be used to turn a simple, well-recognized identity into a public/private key pair. From these powerful mathematics, comes an elegant mechanism for secure business messaging and communication – online and offline, without the need to pre-register recipients.
By using well-known identities as public keys, Identity-Based Encryption (IBE) eliminates the complexity of certificates, Certificate Revocation Lists (CRL) and other costly infrastructure. The practical application of IBE results in a solution that is easy to implement and easy to manage, without the overhead and cost inherent in traditional security solutions. The scalability of the IBE approach means that, for the first time, companies can communicate with their clients through secure business messaging, opening up new business opportunities, better customer service and, most importantly, differentiated competitive advantage.
