A hybrid elliptic curve cryptography (HECC) technique for fast encryption of data for public cloud security

Abstract

Cloud computing provides the users a centralized place for data storage and other commercial applications. To guarantee everything is secure, cloud security has to handle all the devices, apps, and data connected to the cloud. Because of the cloud's robust security, the data and applications may be accessed by the relevant people. The usage of public cloud security ensures that customers always have a trustworthy method of accessing apps and data, which in turn enables service providers to resolve any potential security problems as soon as they arise. This paper presents a public cloud security technique using Hybrid Elliptic Curve Cryptography (HECC). The proposed approach makes keys using a lightweight Edwards curve. The user's Identity Based Encryption is used to change the generated private keys. The proposed key reduction method is used to make the keys even shorter, which speeds up the Advanced Encryption standard (AES) encryption process. The public keys are exchanged using Diffie Hellman key exchange. Throughput and key generation, encryption, and decryption times are used to evaluate how well the suggested model performs. The suggested model fared better than the current models in every way. The suggested method's key creation process takes 0.000025 s, while the resulting encryption process takes 0.00349 s. The achieved throughput is 693.10 kB/s.
