Semiconductor device including encryption section, semiconductor device including external interface, and content reproduction method |
摘要 |
A secure LSI device 1 includes an encryption section 2 for encrypting a program, and an external I/F 50 for inputting/outputting a program or data from/to an external memory 100. In the encryption section 2, the operation of a private key arithmetic processing section 20 is prohibited with respect to a sequence whose execution is determined by a key-generation/update sequencer 30 to be impermissible. In the external I/F 50, a program processing section 51 and a data processing section 55 are structured independently from each other.
