AES Video Encryption – The Ultimate Guide to Streaming Video Security

Streaming Video Security

The live video streaming market is predicted to be worth $70.5 billion USD by 2021. The rise of this industry has coincided with the growth of the internet and the trend towards virtual event attendance, distance learning, remote work, and the development of video for marketing and sales.

The downside to this rapid growth is the equally rising issue of cybersecurity threats. Security firms are measuring an increase in piracy, hacking, and other digital attacks every year, and the video industry is no exception. 

Luckily, there are several video security solutions, including AES video encryption.

In this post, we will examine online video encryption in detail. We will discuss what it is, who should use it, and how it works.

We will wrap this post up with a few additional video security methods.

What is AES Video Encryption?

What is AES Video Encryption?
AES video encryption is the first line of defense for many professional broadcasters.

AES stands for “Advanced Encryption Standard.” TechTarget says that AES encryption is “a symmetric block cipher chosen by the U.S. government to protect classified information and is implemented in software and hardware throughout the world to encrypt sensitive data.”

In video streaming, broadcasters can use AES video encryption for secure streaming. When the video is encrypted, a special key scrambles the video content. 

Unless the viewer has the correct access key, they can’t watch the video. Furthermore, if they try to intercept it, all they’ll see is a scrambled mess of useless data. Authorized viewers will access to AES-encrypted video via their web browser and a secure HTTPS connection.

This entire process plays out in a way that’s transparent to the users. All they have to do is gain legitimate access to the video, by logging in or accessing the right website. The encryption process may be invisible but it provides a significant layer of protection against interception and piracy.

Who Needs AES Video Encryption?

Just about anyone who wants to protect their online video content can benefit from AES encryption.

Simply put, online video encryption can be extremely valuable to anyone who needs to keep the video private. If you need to protect your valuable video content from being viewed or stolen by unauthorized people, AES is for you.

For example, if you have private internal content or if you sell video courses online your videos must remain exclusive. In those cases, videos should remain for subscribers or your internal team only.

AES often works in combination with other security measures to keep your videos as secure as possible.

Although anyone can use AES vide encryption, here are a few types of businesses and industries that benefit from this security measure:

  • Government organizations
  • Enterprises
  • SMBs
  • OTT and entertainment companies
  • Education and eLearning
  • Lawyers

For OTT streaming and entertainment businesses, avoiding content piracy is essential to the business model. For educational institutions and eLearning businesses, the stakes are similarly high. AES encryption can also be highly valuable in corporate and government settings, where unauthorized data leaks can be a significant issue.

Anyone who wants to keep their video content from being copied should consider AES video encryption. Piracy costs the U.S. economy more than $20 billion per year. The price tag internationally, however, is even bigger.

Benefits of Encrypting Video Streams

Online video encryption helps you keep your video content safe from MITM attacks.

AES video encryption prevents “Man-in-the-Middle” (MITM) style hacking attacks. In this type of attack, someone intercepts network traffic to steal sensitive data.

You may have heard that using public, unsecured WiFi networks can be dangerous, and MITM attacks are the reason why. For example, if you log in to your bank at the local Starbucks, and you might have exposed your financial details to a hacker.

In general, these types of attacks are relatively simple. Tools such as packet sniffers are widely available, and any person with even a little technical knowledge can download and get one running easily. 

More concerning, however, are the professional hackers. These individuals look to gather sensitive information, corporate details, and the latest popular video content to resell on the dark web. This a growing problem. 

Akamai, one of our top-tier content delivery networks, has found that credential theft for online video subscriptions is a major issue. Millions of accounts are compromised every year.

AES video encryption allows you to prevent these types of attacks completely. Anyone snooping on your streams will be halted by AES encryption. This gives you protection against piracy, data theft, intellectual property appropriation, and more.

Technical Overview of AES Development and Strength

AES encryption
The technology behind AES encryption is so sound that banks and other major institutions rely on it as the first line of defense against attackers.

As computers have grown more powerful, data encryption technology has been forced to grow stronger, as well. AES was originally released in 2002 by the National Institute of Standards and Technology. It was designed to be as secure as possible, be free, and be relatively easy for programmers to implement.

Since then, AES has proven itself to be a strong and reliable encryption method. It’s still widely used in banking, government, military, and business. 

AES is free, open-source, and built-in to the hardware and software of many devices. Any time you connect to a secure WiFi network or use a VOIP calling app, you’re using AES.

Whether it’s used in video or for anything else, AES works the same way. It uses the Rijndael algorithm and symmetrical block ciphers to encrypt the content. This is a complex process of mathematical substitution that repeats to turn content in a jumbled mash. 

Unless the proper key is applied, the data is completely worthless. For example, AES encryption may turn this very sentence into something like “aflkjsfasf12 324spoudsafa 23dsgmzxc qpoaqwe67 asdj2k39.”

However, it’s important to be aware that it is possible to bypass AES video encryption. Like most security measures, it won’t stop someone who has legitimate access to your content from duplicating it, since anyone can point a video camera at their screen and duplicate your content.

Therefore, AES should be just one part of your larger security strategy.

AES-256 vs. AES-128

AES-256 is the recommended key for top-notch security.

There are some variations within AES technology. The AES standard uses key sizes of 128, 192, or 256 bits. This means that the key (or the secret code that secures the content) is either 128, 192, or 256 characters in length.

Those with the proper encryption key can use it to reverse the encryption process and see the original unencrypted data. 

In general, AES-128 should be plenty secure for most use-cases. If you’re sending particularly sensitive information, you can choose to use AES-256. The only drawback is that encoding and playing back this video will require a little more CPU resources from your viewers.

However, in 2015 the NSA stopped recommending the use of 128-bit keys for AES encryption and started recommending 256. Today, most professionals recommend 256-bit keys as a matter of course. Most modern hardware should have no trouble at all decoding video encrypted with a 256-bit key.

How to Make AES Part of Your Security Strategy

Implement AES video encryption might sound rather technical, but if you’re using the right online video platform, implementing AES encryption is as simple as a single click of a button on your video dashboard.

By turning on this security feature, you can provide a significant layer of security for your content. It’s all invisible to both you and your viewers. There’s no programming required and nothing new to learn.

Additional Cyber Security Measures

    Thank for all of these valuable information. I have a small inquiry, is the video format a big issue when it comes to the AES encryption algorithm?? Is it required to have a certain format for the video so it can be processed through the AES encryption?? Does the video’s format differ at all??

    • Harmonie Duhamel says:

      Hi Fady, the format does not matter as long as it’s a video format. It’s worth noting that we encode all video uploads to mp4 anyway, so their source file format won’t come into play unless they have DNE as a rendition. Hope this helps and please do not hesitate to reach us via email if you have further questions at Best regards

      • Fady says:

        Thank you for fast reply!! The thing is all the videos we are working on are in H.264 video format. These videos undergo an encryption process using the AES algorithm we apply. From what you are saying you recommend change the video formats to mp4 as I reckon, but will it be fine to leave them as they are? Knowing that these videos will be used in a Live video stream.

  2. Marty Martin says:

    can a screen capture software program like movari record a live stream or a video from archive ?
    If I purchased the right to view a show can those types of software copy the video ?

    • Harmonie Duhamel says:

      Hi Marty, I am not sure to understand what you try to achieve with an online video platform? Could you please give me more details about your project? Thank you for the information. Best regards,

  3. Mod says:

    I have developed a video encryption algorithm / program that works on any video format, and I would like to test it on a benchmark video dataset, can you provide me with a dataset.
    My work is non-commercial, for dissertation work.

    • Harmonie Duhamel says:

      Hi Mod, I hope you are well. We are not a content provider but a service provider and we do not have a video dataset. Best regards,
