摘要：Digital video contains potentially very important data that needs high protection, So researchers began competing in how to find ways to preserve data from illegal access, including the encryption that was used to protect the video content (fully or selectively). Where all methods aim to provide the highest levels of protection for the individuals. So the challenges began in designing strong encryption algorithms that are hard to break and also be fast.The goal of this study is to show some of the techniques used in video encryption, with mentioning the pros and cons of each technique to identify these cons and avoid them in future work. From our study and analysis, it was found that most technologies achieve one aspect, either increased accuracy rate or speedup implementation time, especially when implemented in real time , because both negatively affect the other. For example, methods that use lightweight algorithms such as RC4, chacha and others focus on speed, while other algorithms such as RSA,DES..etc focus on the level of security. Therefore we suggest combining the advantages for algorithms by hybridization to building a fast and robust algorithm that can be implemented in real-time.
