Enhancing Secure Communication Through Hybrid Steganography and Public Key Cryptography
Abstract: This research pioneers an innovative paradigm in secure data communication by seamlessly merging Public Key Digital Image Steganography with public key cryptography. The proposed method leverages the formidable strength of the RSA algorithm, employing a robust 1024-bit key size for secure data encryption. In parallel, the imperceptibility of the F5 steganographic technique is harnessed to clandestinely embed the encrypted message within a cover image. Unlike conventional methods, our scheme introduces …

Lossless and Reversible Data Hiding in Encrypted Images with Public Key Cryptography
Abstract: In this paper, system uses the cryptography and steganography concept, which proposes a lossless, reversible, and combined data hiding methods for images encrypted by public key cryptosystems with probabilistic and homomorphic properties. In the lossless method, pixels of encrypted images are replaced with new values to embed additional data into LSB-planes of ciphertext pixels by multiple layer wet paper coding. Thus, original data can be directly extracted from encrypted image, …

Discrete Cryptography
Abstract: The theory of Public Key Cryptography (PKC) was introduced by Diffie and Hellman [2]. There was the key agreement protocol based on the Discrete Logarithm Problem (DLP) in 1976. In 1985, ElGamal [1] applied the concept of [1] and presented the first real and practical PKC. The security of this PKC interacts with the hardness of DLP. The discrete cryptography is presented in this paper. Cryptography interacts with the hard …

Data Hiding Techniques Using Steganography Algorithms
Abstract: Steganography is the method of hiding information or data in a very peculiar manner using cover objects and various techniques. In the last two decades, the adaptability of the digital communication and information sharing arouses the need for data susceptibility and thus steganography comes into play. Derived from Greek word “steganos” meaning hidden, comes steganography or “concealed writing”. It focuses on creating a safe and secure communication link between the …

Efficient Computation of Point Multiplication in the Implementation of Elliptic Curve Cryptography
Abstract: In recent times, elliptical curves have been used for public-key cryptographic and signature schemes in information security. The security provided by elliptic curve cryptographic protocols, either using signature or public-key encryption, is entirely based on the discrete logarithm problem. The discrete logarithm problem says that for a given a point Q that is a certain multiple k of a fixed point P, how to find the value of k in …
