Encryption, Data security
As distributed computing becomes more and more popular, there is an urgent need to protect privacy of massive sensitive data stored in clouds and blockchains. The traditional encryption schemes can not allow searching on encrypted data without decryption first. The proposed fully homomorphic encryption method is a practical encryption scheme that protects the privacy of massive amounts of sensitive data stored in clouds, blockchains, and company databases. In addition to this, the FHE scheme allows for all possible searches to be performed in encrypted form, and decrypted by the data owner.
• Data is encrypted with a private key, decrypting only for the user with the private key
• Data encryption has a much smaller cipher-text expansion, reducing the total file size
• All search functions can be performed with this method, allowing information to be found in encrypted form
