Description

Method and system for realizing safe transmission of internet television content
Technical Field
The invention relates to an information security technology, in particular to a method and a system for realizing the security of the content transmission of an internet television.
Background
With the increasing popularity of internet television, users may access various online content, such as video, audio, applications, etc., through the internet. However, internet television has problems of legal broadcasting and security risks in the process of content transmission, and various security threats and attacks, such as data tampering, illegal copying, unauthorized access, denial of service attack, man-in-the-middle attack and the like.
In the prior art, an encryption algorithm and a secure transmission protocol are generally adopted to carry out data encryption transmission to ensure the security of information data. The encryption algorithm is a mathematical algorithm for converting original data into encrypted data to protect confidentiality of the data. Common encryption algorithms include symmetric encryption algorithms (e.g., AES, DES) and asymmetric encryption algorithms (e.g., RSA, diffie-Hellman). The symmetric encryption algorithm uses the same key for encryption and decryption, while the asymmetric encryption algorithm uses a public key for encryption and a private key for decryption. The encryption algorithm is used for encrypting the content, so that the content cannot be leaked or tampered in the transmission process, and only a decrypted receiver can restore the content. However, the problem of data transmission is solved by adopting an encryption algorithm, the risks of attack and tampering of a content source station cannot be avoided, and if the upstream content is tampered, the downstream cannot recognize the tampering, so that the broadcasting risk is caused.
The secure transmission protocol is a network communication protocol for establishing a secure communication channel and encrypting data for transmission. The most common secure transport protocol is HTTPS (Hypertext Transfer Protocol Secure), which uses SSL (Secure Sockets Layer) or TLS (Transport Layer Security) protocols for encrypted communications at the transport layer. Secure transport protocol (HTTPS) is used to encrypt the transport channels, ensuring confidentiality and integrity of the content during transport. However, the secure transmission protocol cannot handle the man-in-the-middle attack scenario, and the transmitted content still has the possibility of being tampered with.
Therefore, the network information data transmission in the prior art only solves the problem of local scenes, and still has the problems that the safety can not be fully ensured and the loopholes remain in the safety broadcasting.
