Two-factor Authenticated Key Agreement Protocol for Healthcare SystemTwo-Factor Authenticated Key Agreement Protocol • January 19th, 2018
Cloud computing provides a services for sharing and storing the data. Both cloud server and trusted authority are semi- trusted party. The generation of trust value for cloud server and trust authority is a tedious process. Many researchers proposed different methods for generating trust value and it is still in open research. So, we propose a trust evaluation scheme for cloud data security using fuzzy based approach. By using fuzzy based approach, the trust value is generated. After obtaining the trust value, data can be re-encrypted by a trusted authority for security. After re-encryption the data are stored in cloud server which then can be shared and stored securely in cloud.
