Ensuring end to end Security is the implicit requirement of any communication system. While there are several key based encryption techniques in practice today, they fail to provide foolproof security. In order to decrypt and consume the message, the encryption key is to be transferred to the receiving end over an alternative channel. It is still risky and often retrieved by a hacker with powerful and affordable computing power. Consequently, organizations such as banks and financial institutions handling sensitive information of the customers are hesitant to put the data over the channel to consume cloud based applications. This talk provides an alternative for the encryption key transfer, called homomorphic encryption wherein decryption of the data is not required before the consumption of the applications, especially the AI inferencing models, over the cloud. Homomorphic encryption however has a set of Implementation issues, solved to an extent by the upcoming quantum computing technology.
