Implication

This algorithm integrates SHA-256 hashing and DNA encoding, showing improved security for medical images.

Key Points

  • The proposed encryption algorithm achieves high NPCR of 0.997, indicating strong pixel change sensitivity.
  • Experimental results show a UACI of 0.289, confirming the method's effectiveness in ensuring image security.
  • The integration of DNA encoding and logistic maps allows for enhanced data integrity verification.
  • This method's scalability maintains robust performance with JPEG quality factors of 90 and 70.
