How can this be done? Basically, using one acronym, AES, which stands for Advanced Encryption Standard, which is a symmetric cipher used to encrypt sensitive data. It is a fast algorithm which is more suited to encrypt messages because it has its limitations, primarily being how to determine which key to use between the parties communicating. In terms of trying to compromise AES encrypted content, just to give you some sort of idea how secure it is, it would take 1,000,000,000,000,000,000 years to crack. So it is with a good guarantee that if your data is encrypted with this protocol that it is somewhat safe to say the least 🙂 .
However there is a solution much better, which brings me to RSA, which is one of the most successful asymmetric cryptography systems available today. This protocol was originally discovered by the BIA(British Intelligence Agency) in 1973. It was however rediscovered by civilian cryptographers Rivest, Shamir and Adleman who were credited with the find after stumbling upon the protocol by accident. As we discussed AES an asymmetric algorithm above, RSA works completely different as is uses two different keys , a public and private key. They work in tandem with one another as one is used to encrypt and the other used to decrypt. It is primarily because of the aforementioned features that allow RSA algorithm to be used in a labyrinth of uses m from bio-metric capabilities, digital signatures to even media encrypt and decryption(As evidenced by RSA used for encrypted video streaming) . It is therefore estimated, that standard desktop computing power would take 4,294,967,296 x 1.5 million years to break a RSA 2048-bit encrypted content. Or, in other words, a little over 6.4 quadrillion years.
With all the new ways to protect content in this age of the internet, it is a complete travesty that streaming, emails, and most transmissions over the internet are in plain text or unsecure form, but we will focus mainly on video streaming properly encrypted video streaming. I believe in fairness to other companies, it must be mentioned that a main reason why videos are unsecured and encrypted is that it takes alot of computer power.Currently there are mainly three ways of streaming encrypted video:
Secure RTP -standard based around AES 128bit encrytion, mainly used by VOIP systems
HTTP Tunneling -This method is not widely used, but it simply requires you to send video over HTTP but to encrypt it you would use HTTPS thus using TLS.
HLS – this uses a combination of HTTPS and TLS
The only limitation is that because each of the above mentioned methods uses AES then , streaming the video securely would mean that your device is able to perform AES encryption at the same data rate it is capable of encoding video. With RSAplay it is all done for you worry free, no need for expensive hardware or worry about computational power, this cloud video encryption host takes care of all the brunt work , just enjoy content to your device anywhere securely
