Abstract: A virtual channel table for broadcasting protocol and a method for broadcasting by using the virtual channel table includes identification information identifying and permitting discrimination of active and inactive channels contained in the virtual channel table. At a receiver, the virtual channel table transmitted from the transmitting side is parsed, thereby determining whether the current received channel is an active or inactive channel.
Abstract: A secure flash-card reader reads a user ID from a secure card and finds a matching entry with a hashed password in a user table on the reader. An encrypted key is received from a secure host that hashes and encrypts a password the user types into the host and the user's ID. A card decryption engine uses a random number to decrypt the encrypted key and recover the hashed password and user ID from the secure host, which is compared by a comparator to the hashed password and user ID from the user table. A mismatch causes an access controller to block access to encrypted data on the secure card. Flash data is transferred over a flash-serial buffer bus between flash-card controllers and a RAM buffer. An encryption engine on the flash-serial buffer bus encrypts and decrypts data and connects to a serial engine to the host.
