About Voltage IBE

Voltage IBE is a public key cryptography system that uses common identities (such as an email address or screen name) as public keys, eliminating the need for certificates, Certificate Revocation Lists (CRL) and other costly infrastructure. Voltage IBE results in a solution that is easy to implement and easy to manage, without the overhead and cost inherent in traditional security solutions. Voltage IBE is ideal for use with financial services customers and medical patients who expect communication to be kept private and secure and also want ease-of-use and low-cost. Voltage IBE solutions are:

• Easy to implement and easy to manage – eliminates the overhead and costs inherent in traditional security solutions such as PKI
• Highly scalable – no storage of keys or messages, and no need to contact online servers; allows the solution to scale dramatically without the need for additional infrastructure
• Easy to use – no need for end users to worry about keys or certificates.
