In this paper, different 2×1 and 2×2 multiple input multiple output (MIMO) antennas were investigated with changing substrate shapes and changing the placing of the patches on the substrate, all the investigated antennas based on FR-4 substrate are characterized by = 4.4, and loss = 0.02, with a partial ground. The original antenna covered 3.4 to 13.5 GHz. The best simulation results of the proposed 2×1 MIMO antenna received for 2×1 inverted with high ultra-wideband (UWB) with bandwidth up to 40 GHz, the received maximum gain was up to 6.51 dB, with an average gain of more than the original single antenna at about +1.27 dB. The best of eight 2×2 MIMO antennas configurations that give good results were shown. The best-received gain compared with a single antenna gain were at 4.2 GHz about +2.73, +1.17, and +0.92 dB for plus-shaped, loop, and chair-shaped respectively. A comparison between the proposed MIMO antennas and other reported works were done. The proposed MIMO antennas give a good maximum gain and are suitable for different narrow bands within the UWB such as wireless local area network (WLAN), worldwide interoperability for microwave access (WiMAX), aeronautical radio navigation (ARN), International Telecommunication Union 8-GHz (ITU-8), and X-Band applications with the ability to give high gain without the need to increase the radiated power of the transmitter antenna.

Color digital images are one of the most common types of digital data circulated through various social media, due to their use in important vital applications. The digital image may be confidential or of a personal nature, or it may provide a carrier of confidential data, which makes providing a secure method of protection for it extremely important in order to protect the image from penetration and protect it from any side that has nothing to do with the image. In this research, a secure method will be presented to protect data, and this method will be multi-purpose, as it can be used to protect short and long secret messages and protect digital images regardless of their type or size. The high level and difficult to penetrate degree of protection will be achieved through the use of two colored images to generate two secret private keys to be used in the process of encrypting and decrypting confidential data. This method will be applied in order to prove the extent to which this m...

It will be show how to generate 1D and 2D private keys with integer values and with fractional values, these key will be generated taking in mined the process of optimizing the generation time and the selected length of key which can optimize the process of cryptography.

Many data cryptography methods are based on DES; these methods have a lot of disadvantages such as fixed block size, fixed private key length, multiple rounds and sometimes low level of security. In this research paper a method of secret messages cryptography will be introduced. It will be shown that the proposed method can be easily used to apply data cryptography for short, medium and long messages keeping the values of the quality parameters (MSE, PSN and CC) acceptable. The method will use three image_key to generate the required private keys needed to calculate the number of rotation digits used in character rotation. The images are to be kept in secret and it is possible to change them any time without changing the operations used in the proposed method. The proposed method will be compared with DES to show the improvements provided by the proposed method.

The purpose of steganography is to conceal the existence of the secret message in the holding image, thus making a message unreadable by a third party. Steganography is an important process due to many factors such as the confidentiality, personality of the message to be sent from the sender to receiver through unsecure communication environment. In this paper we will introduce LSB2 method of data hiding in order to double the capacity of the holding image, by doubling the maximum message size which can be covered by the image. The proposed methodology of applying LSB2 will be implemented and tested in order to prove the efficiency of this method comparing with LSM method.

Standard methods used in the encryption and decryption process are implemented to protect confidential data. These methods require many arithmetic and logical operations that negatively affect the performance of the encryption process. In addition, they use private keys of a specific length, in addition to the fixed length of the data block used in encryption, which may provide the possibility of penetration of these methods, thus decreasing the level of security. In this research paper, a new method of digital image cryptography is introduced. This method is based on using a color image as an image_key to generate a sophisticated matrix private key (MPK) that cannot be hacked. The proposed method uses an initial state to set the required parameters, with secret information needed to generate the private key. The data-block size is variable, and the complicity of the MPK depends on the number of selected rounds and the data-block size. The proposed method is appropriate for publicat...

Color digital images are greatly affected by salt and pepper noise, which negatively affects the clarity of the image and its characteristics. In this paper research we will investigate various filter used to deal with salt and pepper noise, a comparison will be done between these filters according to the calculated values of MSE and PSNR. An improvement procedure will be added to each filter to show how this improvement will enhance the values of MSE and PSNR and thus enhance the quality of the denoised image. Various noise densities will be experimented and it will be shown how median filter can be highly recommended to reduce the negative effects of salt and pepper noise.

Least significant bit method is one of the most popular methods of data steganography, this method is very simple and provides good values for MSE and PSNR. LSB method is not secure enough and the embedded secret message can be easily hacked by any person with any programming experience. To enhance the security level of LSB and to protect the secret message from being hacked and addition stage is recommended. This stage adds a necessary protection without affecting the quality parameters and the efficiency of LSB. The protection process is based on using a complex private key, this key is generated by sender depending on the block size and the selected image size and kept in secret to be used by the receiver, the private key can be changed or updated any time, when the needs arise.

Multiple methods are used to hide secret messages in digital color images, and the most important and most common is the least significant bit (LSB) method. The LSB method is a known and exposed method, and anyone with programming experience can retrieve the secret message embedded in the digital image. In this paper research we will add some enhancements to improve the security level of LSB method to protect the embedded secret message from being hacked. A simple method of secret message cryptography will be used to encrypt the secret message before bedding it using LSB method. The method will be based on using color image as an image_key; this image_key will be resized to generate the needed secret private key used to encrypt-decrypt secret message. The length and the contents of the generated private key will dynamically change depending on the message length and the selected image_key. The selected image_key will be kept in secret without transmission and will be known only by t...
