Development of an application to protect files shared on cloud services based on elliptic curve cryptography

Abstract

Cloud-based services allow people easily store and share their files with others. Cloud providers must adhere to security and privacy policies to ensure their users' data remains confidential and secure, while ensuring that usability is not impacted. To ensure the security of a cloud service, the cloud service providers have their own solutions. Our Fen Clown project provides best security with minimal impact on usability and performance. implements ECIES Hybrid Encryption Scheme to encrypt data and uses ECDSA to sign permissions.
