Abstract: A data processing system includes an application processor, a memory device, and a channel connecting the application processor and the memory device. The application processor encrypts first data using a first encryption key and a first initialization vector in response to a write command, and transmits first encrypted data to the memory device through the channel. The memory device decrypts the first encrypted data using a second encryption key and a second initialization vector, and stores first decrypted data in a memory core. The second encryption key and the second initialization vector are stored in the memory device. The first encryption key is the same as the second encryption key, and the first initialization vector is the same as the second initialization vector.

Abstract translation: 数据处理系统包括应用处理器，存储器设备和连接应用处理器和存储器设备的通道。 应用处理器响应于写命令使用第一加密密钥和第一初始化向量来加密第一数据，并且通过该信道将第一加密数据发送到存储器件。 存储装置使用第二加密密钥和第二初始化向量解密第一加密数据，并将第一解密数据存储在存储器核心中。 第二加密密钥和第二初始化向量存储在存储器件中。 第一加密密钥与第二加密密钥相同，第一初始化向量与第二初始化向量相同。
