Abstract

The invention discloses a set-top box-based secure information transmission system and a set-top box-based secure information transmission method. The secure information transmission system comprises a secure algorithms library, a key management component, an authentication component, an encryption / decryption component and a verification component; the secure algorithms library is used for providing transmission encryption and decryption algorithm supports; the key management component is used for managing a public key and a private key of a user and generating a dynamic key; the authentication component is used for determining the identities of double data transmission parties; the encryption / decryption component is used for implementing encryption and decryption of data; and the verification component is used for verifying validity and integrity of the received decrypted data. According to the technical scheme, the transmission of the sensitive data on a set-top box is safer and more efficient by combining a symmetric encryption algorithm and an asymmetric encryption algorithm.

Description

technical field

[0001] The invention relates to the technical field of digital home, in particular to an information security transmission system and method based on a set-top box. Background technique

[0002] With the continuous advancement of digital home technology, more and more functions are realized on the set-top box. The currently used set-top boxes have realized functions such as playing games, checking the stock market, banking services, etc., which greatly facilitate people's lives.

[0003] With the diversity of services provided by the set-top box, the security of content services becomes more and more important. For example, bank account password information or game account information are sensitive information that needs to be protected, so the information transmission on the set-top box needs to be secured.

[0004] In the existing technical solution, generally, the message to be sent is encrypted and then sent. Encryption algorithms are divided into symm...
