The increasing mobility of data, as it ping-pongs between clouds, data centers and the edge, has made it an easier target of cybercrime groups, which has put a premium on the encryption of that data in recent years.
Cybersecurity vendors have stepped up, developing strong and efficient ways to encrypt data both while it’s at rest and when it’s in transit. However, there is a glaring weakness. When the data is being processed, analyzed or used by applications in another way, it needs to be unencrypted, making it more vulnerable to attack.
To counter this, some major IT vendors are pushing forward with a decades-old encryption idea that was first talked about in the late 1970s but not successfully demonstrated for the first time until 2009. Since then, interest in fully homomorphic encryption (FHE) has increased, largely paralleling the rise of cloud computing.
