Porticor Uses Split-Key Encryption To Enhance Cloud Security
Porticor Uses Split-Key Encryption To Enhance Cloud SecurityCloud security software startup Porticor announced that it has improved its Porticor Virtual Private Data (VPD) environment to not only support encrypted data in the cloud, but also protect the encryption keys of data while being used.
The company said that it uses split-key encryption technology to keep encryption keys in a customer’s control. The master encryption keys are maintained in a fully encrypted state and remain secured even while being used to access cloud data, the company said.
Porticor stated that its VPD is the world’s first commercial application using homomorphic encryption technology for combining and splitting encryption keys. As application access is granted to stored data, the master key is never exposed in an unencrypted state. Even if the key is stolen, it cannot be used to access a data store.
Pricing for the technology starts at $65 per month per Porticor.
