In order to effectively solve the increasingly prominent network security problems, cryptographic algorithm is the key factor affecting the effectiveness of IPSec VPN encryption. Therefore, this paper mainly studies cryptographic algorithms and puts forward the following solutions: briefly analyze the concept and function of IPSec VPN, as well as the basic theoretical knowledge of IPSec Security Protocol and cryptography, and analyze the traditional cryptography, modern cryptography, symmetric cryptographic algorithms and asymmetric algorithms, and their security. At the same time, the executable and security performances of AES and DES algorithms are compared and analyzed. This paper studies the elliptic curve encryption algorithm ECC, expounds the mathematical basis of realizing the algorithm, and compares and analyzes the security performance and execution efficiency of ECC. Based on the above two algorithms, a hybrid encryption algorithm is proposed, and the realization mechanism of the hybrid encryption algorithm is studied and discussed. The hybrid encryption algorithm combines the advantages of ECC and AES. The algorithm selects 128-bit AES and 256-bit ECC. In order to better cover up plaintext C, AES is used to encrypt information. While enhancing security, speed is also considered. The improved encryption, decryption, and signature authentication algorithms are relatively safe and fast schemes. ECC algorithm is improved, and on this basis, ECC algorithm and AES algorithm are combined. Moreover, HMAC message authentication algorithm is added, and the performance of the improved algorithm is significantly improved.

Now a day‟s the uses of devices such as computer, mobile and many more other device for communication as well as for data storage and transmission has increases. As a result there is increase in no of user‟s also there is increase in no of unauthorized user‟s which are trying to access a data by unfair means. This arises the problem of data security. To solve this problem a data is stored or transmitted in the encrypted format. This encrypted data is unreadable to the unauthorized user. Cryptography is a science of information security which secures the data while the data is being transmitted and stored. There are two types of cryptographic mechanisms: symmetric key cryptography in which the same key is use for encryption and decryption. In case of asymmetric key cryptography two different keys are used for encryption and decryption. Symmetric key algorithm is much faster and easier to implement and required less processing power as compare to asymmetric key algorithm. The Advanced Encryption Standard (AES) was published by the National Institute of Standards and Technology (NIST) in 2001. This types of cryptography relies on two different keys for encryption and decryption. Finally, cryptographic hash function using no key instead key it is mixed the data.

Cryptographic techniques play crucial role when users exchange information. Multimedia plays an important role in learning and sharing experiences. When multimedia contents are shared among the users, it faces security threats. Usually multimedia contents takes much space. Encryption technique should be time efficient. In this work we consider four encryption techniques: Blowfish, AES, XOR and RSA and four types of media content: text, image, audio and video. Simulation shows that AES is time efficient than others. Comparing between symmetric and asymmetric cryptography, symmetric cryptographic techniques take less time than asymmetric technique.

Thiscan be done with the help of cryptography and cryptographic algorithms that can help secure this entire process. With cryptography, it is possible to securely transfer sensitive data to ensure that it cannot be read or tampered by a third party. Cryptography and its related algorithms can also be used to secure the network for safe transfer and storage of sensitive data.

Data is a file that can be confidential so it requires a data security process to maintain confidentiality. Kripotgrrafi is a data security process that can be used based on the use of algorithms, one of which is AES. AES is a modern algorithm that can be modified to improve confusion and diffusion in cryptography. AES combination can be done using Polybius which has cryptographic diffusion properties. This study modified the AES using 6x6 and 10x10 polybius matrices that were performed on plaintext and plaintext and keys. Analysis was carried out based on the highest bit change rate found in modification II in the plaintext and 6x6 matrix keys, which amounted to 51.8% using the avalanche effect test. The results of the AE compared to the expected results using chi square with the modified AES results can increase the AE by 5% with the real level is 0,05 and the degree of freedom is 4 . Execution time was tested in this study with the results of the AES modification time longer than the standard AES because the complexity of the algorithm affects both encryption and decryption time.Abstract Data is a file that can be confidential so it requires a data security process to maintain confidentiality.
