Go to Editorial ManagerBecause elliptic curve cryptography offers a promising trade-off between security and computational performance, the field of current cryptographic techniques has taken a particular interest in it. Two basic digital signature algorithms—the Elliptic Curve Diffie-Hellman Algorithm (ECDH) and the Elliptic Curve Digital Signature Algorithm (ECDSA) are the subject of this performance analysis and comparison. These methods are based on elliptic curve cryptography. The analysis takes into consideration realistic application demands as well as factors like key length and security level. The results provide useful information on trade-offs between performance and security. A list of acceptable ECDSA requirements for digital signatures was used for the comparison. These characteristics are sign, sign/s, no PC verify, no PC verify/s, siglen, keygen, keygen/s, verify, and verify/s.
Technology and digital communications have advanced so that digital photos, videos, or text may be easily manipulated by those not authorized to do so. In addition, the availability of specialized picture editing programs like Photoshop has simplified the process of altering photographs. At first glance, there may seem to be no problem, especially when an image editing method is necessary to delete or add a certain scene that increases the picture's beauty. But what about personal images or images with copyright? Attempts are constantly made to spoof these images using different approaches. Therefore, measures to reduce the likelihood of counterfeiting in digital and printed forms of media are required. The proposed approach aims to detect a counterfeit in images using a unique generator that conceals the data represented by the embedded watermark utilizing modern visual cryptography and hash algorithms. Image extractions may easily be analyzed for signs of forgery. As a result, our approach will detect and validate phony documents and images.
