Abstract

Basically, confidential data needs to be stored or delivered in a certain way so as not to be known by unauthorized foreign parties. And to overcome the problem then created the science of cryptography and steganography. One example of a cryptographic algorithm is the Rivest Code 4 (RC4) algorithm, and one example of the steganographic algorithm is End Of File (EOF). Cryptographic algorithms can be combined with steganographic algorithms so that the secret messages we have are more secure than foreign interference. First of all secret messages that we have first encrypted using the Rivest Code 4 (RC4) algorithm, then the encrypted ciphertext is hidden / inserted in the image / image media with the End Of File (EOF) steganography method.Keyword: Kriptografi, steganografi, rivest code 4, end of file, cipherteks

Abstract

MANET is a network model cordless (wireless) from mobile devices that can be setup dynamically from anywhere and at anytime without using a fixed network infrastructure. Ease of use and it is without a fixed infrastructure (less infrastructure) makes this model very suitable for use in critical situations, such as in the aftermath of disaster, isolated areas and areas with minimal communications network resources. To maximize the utilization and use of MANET network system, especially on the determination and selection of the best route to a node can connect and transmit the packet from the source node to the destination node to be optimized. This study was done to improve the performance of packet delivery by creating a node that functioned as a gateway and client using routing protocols Ant-Based Routing Algorithm (ABRA) so as to reduce the processing time (overhead) that often occurs in MANET network. Testing is done with a number of different nodes of 10, 20, and 30 nodes, with a bandwidth of 5 Mbps, 5 Mbps and the packet area of 10x10 m. The test results demonstrate the value of performance metrics on throughput and delay have optimal performance and low overhead so that the process of communication in the area of MANET network can take place with the stable. Keywords: Manet, ant-based routing algorithm, networking

Abstract

Image encryption is a technique to protect the confidentiality of images from illegal access. With image encryption, people who do not know how the image is hidden will not know how to open it. Encryption is needed because in today's digital era digital images are easily stored or transmitted through public channels such as the internet. Image transmission through public channels is prone to tapping and storing images in storage media prone to access by parties without authority. For this reason, it is necessary to do a cryptographic method to secure confidential images from parties who do not have the authority to understand the actual image. This study presents an image encryption algorithm using Pohlig Hellman's Algorithm. The Pohlig Hellman algorithm is an algorithm used to compute discrete logarithms in a multiplicative group whose rank is not a safe prime number.Cryptography, Image, Pohlig-Hellman
