Elliptic Curve Cryptography and Password Based Key Derivation Function with Advanced Encryption Standard Method for Cloud Data Security

Cloud computing enables efficient management and storage of large data volumes, providing scalable resources and effective solutions for handling extensive data.However, the cloud requires attention in the field of data security, reliability and privacy.To ensure that entire data is secured, cloud security handles all devices, apps and data that are integrated into the cloud.To overcome these problems, the encryption of cloud data is an effective way to secure the data.The Elliptic Curve Cryptography (ECC) and Password based Key Derivation Function (PKDF) with Advanced Encryption Standard (AES) method is proposed for effective cloud data security.Initially, the key generation by Edward Elliptic Curve and the key exchange is performed by using Diffie-Hellman Key Exchange (DHKE).Then, keys are generated for the client's password using the PKDF method and the encryption and decryption of data is performed by using the AES method which effectively secures the data in the cloud through encryption and decryption of data.The ECC and PKDF with the AES method require less encryption time of 0.006s and a decryption time of 0.005ms on 5 KB when compared with Hybrid Elliptic Curve Cryptography (HECC).Cloud computing enables efficient management and storage of large data volumes, providing scalable resources and effective solutions for handling extensive datasets.
