In today’s world, security and protection issues of the transmitted information have turned into a vital worry in media innovation. In the course of the most recent couple of years a few encryption algorithms have connected to secure video transmission. While countless encryption plans have been proposed in the literature and some have been utilized as a part of genuine items, cryptanalytic work has demonstrated the presence of security issues and different shortcomings in the greater part of the proposed interactive media encryption plans. In this paper, International Data Encryption Algorithm (IDEA) is a symmetric key encryption method and utilizations 128 -bitkey more than 64-bit plain content with eight and a half round. To improve the innovation in IDEA, another methodology is presented in which we will set up two distinctive keys for encryption and decoding separately which was single key in IDEA. This will present more security in IDEA by making it an asymmetric key encryptio...

The rapid advancement in the field of computer network and Internet has increased the easiness of Data Communication. This kind of advancement has expanded the dread of sneaking the information while sending information from the sender to the receiver. Picture and video are two of the most essential types of transmitting data. With the assistance of Image and video encryption techniques, a specific arrangement of pictures or recordings can be transmitted without stressing over security. In the proposed paper an extremely straightforward and constant calculation, utilizing pixel mapping, is utilized for the encryption of the pictures which are the fundamental building squares of any video record. In the proposed research paper, the video is divided into number of frames utilizing a MATLAB code and every one of the frames are sequentially stored. Each such frame contains a mix of red, blue and green layers. If we consider a pixel equivalent to 8 bit than every pixel has the value in t...

With the growth of multimedia services over wireless systems, the security of communication over cellular mobile phone networks, wireless access networks, and unreliable mobile ad-hoc networks is becoming a challenging issue. Secure communication implies data confidentiality and integrity, along with authentication, bringing with it commercial viability and protection of intellectual property. Innovatory key management protocols, specialized for multimedia exchange, are now under active development. Whereas encryption algorithms are, for reasons of open scrutiny and validation, not a subject of confidentiality, a shared secret, the session key, must be confidential and that session key relies on the existence of a secret permanent key. If a server can successfully distribute keys to remote clients without interception, the greater becomes the chance of secure communication, even though no side channel and no physical exchange of keys are required. Therefore, the focus of this review is to highlight: the key generation mechanisms, interaction with associated key management protocols; and the strength of key-management protocols against security attacks. In addition, the paper reviews recent patents on multimedia key management and also examines counter-measures present in key management protocols against known key and data attacks.

Videos have been increasingly dominating today's internet traffic, To scale the delivery of massive volumes of videos, various new network architecture like In-network caching of Information centric networking(ICN)is introduced. In-network caching have been grown as an emerging technique to handle the exponential growth of video traffic. However due to increasing of widely attacking surfaces, caching of video content should be done. Existing protocols like HTTPS also fall short of fully leveraging in network caching and there also chances of occurring man in the middle attack. In order to provide a efficient video delivery a new network system architecture is developed. In order to ensure security videos are divided into chunks, and these chunks must be encrypted. Then these chunks are identified by the finger print index. To enable fast and secure video delivery a secure redundancy elimination protocol is introduced. In order to achieve benefits of caching mechanism and to eliminate redundancy cache enabled router is used.

Now-a-days digital video needs to be stored and processed in an encrypted format to maintain security and privacy. For the purpose of content notation and/or tampering detection, it is necessary to perform data hiding in these encrypted videos. In this way, data hiding in encrypted domain without decryption preserves the confidentiality of the content. In addition, it is more efficient without decryption followed by data hiding and re-encryption. In this paper we implement the video encryption using AES Encryption and Decryption. This algorithm was implemented using Micro blaze Processor on Spartan 3EDK FPGA.

An explosion in the internet and other sharing technologies has made transfer and distribution of video content extremely easy. Unimpeded transfer of video and other multimedia content has lead to violation of several antipiracy laws today. Hence, the need to prevent unauthorized distribution and protection of video data is on the rise. This paper demonstrates the lossless video encryption and decryption techniques. For encrypting the frames of the video, column and row shifting method is used, that is transposition cipher is generated. Further a password is used to encrypt the video as well.

Fast lightweight encryption algorithms must be developed to satisfy the level of security and the real time constraints. However the recently proposed lightweight MPEG video encryption algorithms that have been proposed in the past suffer from certain drawbacks. While some of them require hardware support, the others are weak or reduce the MPEG compression ratio. The lightweight encryption algorithm called VEA is fast, satisfies the real time constraint and does not reduce the MPEG compression ratio. However, it relies on the key generator to generate a good encryption key and it cannot withstand the known-plaintext attack. In this paper, improvements to the VEA are proposed namely the Rotation algorithm, the XOR algorithm and one that combines VEA with IDEA (I-VEA). They are able to secure MPEG video with minimal computational overhead, which do not reduce the MPEG compression ratio, do not rely upon the key generator to generate an effective key and can better resist the knownplaintext attack. The Rotation algorithm is the fastest of the three, but is relatively weak. I-VEA is the most secure but it adds the maximum computational overhead. The XOR algorithm is a good compromise between the two

With the fast expansion of a variety of multimedia technologies, further and more multimedia statistics are produced and transmitted in the fields like military, medical and for further commercial field which may have some susceptible information that is not to be supposed to be seen or accessed by or may only be shown partially to the common users. Therefore, security and privacy has turn out to be significant phase. Over the last few years numerous encryption algorithms are introduced to secure and protect the video during transmission. Along with that many efficient multimedia encryption schemes are introduced and real world is using those techniques. In this paper, various techniques are observed described showing encryption methods and video transmission techniques have been studied.
