# Secure Video Communication Using Multi-Equation Multi-Key Hybrid Cryptography
###### Abstract  
The safeguarding of intellectual property and maintaining privacy for video content are closely linked to the effectiveness of security protocols employed in internet streaming platforms. The inadequate implementation of security measures by content providers has resulted in security breaches within entertainment applications, hence causing a reduction in the client base. This research aimed to enhance the security measures employed for video content by implementing a multi-key approach for encryption and decryption processes. The aforementioned objective was successfully accomplished through the use of hybrid methodologies, the production of dynamic keys, and the implementation of user-attribute-based techniques. The main aim of the study was to improve the security measures associated with the process of generating video material. The proposed methodology integrates a system of mathematical equations and a pseudorandom key within its execution. This novel approach significantly augments the degree of security the encryption mechanism provides. The proposed methodology utilises a set of mathematical equations that are randomly employed to achieve encryption. Using a random selection procedure contributes to the overall enhancement of the system's security. The suggested methodology entails the division of the video into smaller entities known as chunks. Following this, every segment is subjected to encryption using unique keys that are produced dynamically in real-time. The proposed methodology is executed via Android platforms. The transmitter application is tasked with the responsibility of facilitating the streaming of the video content, whereas the receiver application serves the purpose of presenting the video to the user. A careful study was conducted to compare and contrast the suggested method with other similar methods that were already in use. The results of the study strongly support the safety and dependability of the procedure that was made available. asymmetric key cryptography; multi-key encryption; dynamic key generation [PERSON]

gadget technology have emerged as significant factors in this particular context. Due to this outcome, online platforms have successfully attracted significant audiences. The viewer base of over-the-top (OTT) services has witnessed a substantial increase due to the widespread prevalence of illegal file sharing and content piracy. A small fraction of registered users voluntarily discloses their login credentials to individuals within their social circles, such as acquaintances and loved ones. Instances may arise where individuals who have subscribed to certain content engage in replicating it and distributing it to others. An OTT provider's capacity to seek legal remedies is impeded by the abundance of similar disputes, despite the legal ramifications involved. The utilisation of cryptography techniques [2] plays a crucial role in mitigating the risks associated with unauthorised file sharing and safeguarding against piracy during video content distribution. On the contrary, many investigations have been conducted wherein cryptography has been employed to limit the dissemination of video content. Most approaches in this context rely less heavily on hardware components. Illegal file sharing and streaming inevitably occur due to certain factors. Symmetric and asymmetric key cryptography are two prominent methods employed to ensure robust security in the communication process. Symmetric key cryptography, also referred to as secret key cryptography, is the predominant cryptographic technique employed in multimedia communication [3; 4; 5]. The Advanced Encryption Standard (AES) is widely recognised as the most effective and extensively utilised form of symmetric cryptography [6]. Websites and web browsers utilise the 128-bit Advanced Encryption Standard (AES) algorithm to ensure robust security for online communication.
