  • Patent number: 7571309
    Abstract: Provided are a method and apparatus for providing a security mechanism guaranteeing transparency at a transport layer. The method includes: receiving a data packet from an application program, and searching key information corresponding to the data packet in key information database; determining whether to request a key exchange module of an application layer for a new key negotiation according to a result obtained by searching key information; and performing encrypting/decrypting based on key information when the key exchange module stores key negotiation information obtained by the new key negotiation in a kernel. The apparatus encrypts/decrypts the data packet at the transport layer of the kernel, thereby providing the application program with security transparency, effectively controlling and making it easily expansible.

  • Patent number: 5905544
    Abstract: In a microprocessor controlled television set, a method for automatically turning on the set which was turned off due to power line noise includes steps for determining when the set is turned off due to noise, storing first data indicative of a prior-to-turn-off state of the set when the set is turned off due to noise and comparing the first data with second data indicative of a turned-off state when noise is removed. As a result of the comparison step, when the fist and second data are the same, the set is automatically turned on. However, if the first and second data are different from one another, the set is re-initialized using the first data. According to one aspect of the invention, when the set is re-initialized, the set must be turned on using a key manipulation. Thus, the user does not need to turn on a set manually when the set has been turned off due to power line noise.
