A semiconductor device may include: a bus; first and second function modules configured to communicate via the bus; a first encryption module configured to encrypt first data output from the first function module using a first encryption key to generate first encrypted data; and/or a second encryption module configured to decrypt the first encrypted data using the first encryption key, to output the decrypted first data to the second function module, and to encrypt second data output from the second function module using a second encryption key to generate second encrypted data. A semiconductor device may include: a bus; first and second modules configured to communicate via the bus; and/or an encryption module configured to use different encryption policies for first data, which is output from the first module and stored in a memory, and second data, which is output from the second module and stored in the memory.

Semiconductor devices and methods of protecting data of channels in the same

A method of operating a host controller interface includes receiving a buffer descriptor including sector information from a main memory, fetching data by using a source address included in the buffer descriptor, selecting one of a plurality of entries included in a security policy table by using the sector information, and determining whether to encrypt the fetched data by using a security policy included in the selected entry.

Security management unit, host controller interface including same, method operating host controller interface, and devices including host controller interface

A method of operating a system on chip (SoC) includes converting plain data into cipher data by using an encryption key and transmitting the cipher data directly to a memory controller which controls an operation of a non-volatile memory. The encryption key may be output by a one-time programmable (OTP) memory.
