ANALYSIS OF CRYPTOGRAPHY ENCRYPTION FOR NETWORK SECURITY AND IMAGE STEGANOGRAPHY TECHNIQUE

Data security involves protecting digital information to prevent unauthorized access to computers, databases, and websites. Cryptography, encryption, and compression are key strategies for data protection. AES is a powerful cryptographic method. Confidentiality, authenticity, integrity, and non-repudiation are crucial for online communication. Steganography enhances message security across networks, using a photo as a cover material. The smart grid offers flexibility, reliability, and efficiency in power production and distribution. To protect privacy and confidentiality, grayscale cover images undergo discrete wavelet transformation (DWT) and a chaotic map is applied to the secret image. This paper also discusses the use of cryptography and network encryption to secure wireless network data transmission. It emphasizes the importance of data protection for wireless network sensors linked to base stations. Network security is crucial as the world transitions into the digital world, addressing issues like administrator-managed data and communication technology. Cryptography aims to protect networks from attacks and intrusions, while intrusion and computer protection technologies are also used.
