基于智能电视电子支付对安全存储、数据存取的应用需求，提出了一种基于通信双方的ID作为公钥进行认证和密钥协商的机制，利用对称加密算法，实现智能电视与安全芯片之间的数据传输的安全保护，降低了安全芯片的实现规模和系统复杂度。结果表明，在同等安全保护强度下，基于这种机制的安全芯片实现规模约为ECC的1/6和RSA的1/4，降低了系统的总体成本。

An authorization method and a simple key agreement protocol based on both sides’ IDs of participants are proposed to meet the requirements for secure storage and secure access of smart TV payment. Combined with symmetric encryption algorithms, the data transmission and data access protections between smart TV and security storage chip are realized and the scale and complexion of the security storage chip are reduced also. The result shows that the chip gate complexity has been reduced to about 1/6 of ECC and 1/4 of RSA with the same encryption strength.
