Securing Data in the Image Using SHA & ECC

Networks have expanded globally, and information is now available digitally. Due to the volume of data being exchanged online, data security has become a difficult problem. Cryptography provides integrity, confidentiality, non-repudiation, and authenticity to the secret data. Symmetric & asymmetric cryptographic techniques are used today for hiding any confidential information from unauthorized persons. The combination proposed is the asymmetric algorithm (ECC) and a hash function (SHA). This research study introduces a new technique for encrypting and decrypting text that uses elliptical curve cryptography (ECC) to improve data security and a secure hash function (SHA-3) to ensure data integrity. When compared to the previous method for text encryption (RSA), the suggested solution of SHA with ECC is more effective. Compared to other cryptographic algorithms, it offers a higher level of security with a smaller key size.
