Information safety has become a vital issue and data encryption and decryption have lately been vastly researched and developed. There is a need for a powerful encryption and decryption which is very tough to crack, so cryptography plays a major role to fulfill these demands. Moreover, parallel algorithm is rapidly becoming cost and resource-efficient as a result of a unified approach to solve computer problems and wide-ranging problems encountered in applied sciences and engineering applications. In this paper, a parallel environment has been utilized to construct a new encryption system, based on involving the so-called 'zig-zag' ordering that is used in JPEG data compression. A new chaotic system of three dimensions will be produced to eliminate the common encryption systems problems.

The rapid development of most multimedia technologies led to the creation and transmission of much of this type of data in various fields, including medical, military and commercial, which contain sensitive information that can only be accessed by the competent authorities. Because of this, privacy has become vital. Many encryption algorithms have been used to provide security for video transmission. In this paper, NTRU and chaotic algorithms are used for video encryption, which includes sensitive information. The system is designed to encode AVI, WMV, MOV, MP4 and other video file formats. This type of video is encrypted using the NTRU algorithm and decrypted using chaotic algorithm to ensure a high level of strength and security, thus speeding up the encryption process and returning the video to its original location without losing any data. Visual Basic .net 2015 was used to implement this system.
