Abstract: Provided are an arithmetic method and apparatus for supporting Advanced Encryption Standard (AES) and Academy, Research Institute and Agency (ARIA) encryption/decryption functions. The apparatus includes: a key scheduler for generating a round key using an input key; and a round function calculator for generating encrypted/decrypted data using input data and the round key. Here, the round function calculator includes an integrated substitution layer and an integrated diffusion layer capable of performing both AES and ARIA algorithms.

Abstract: A computer system uses a virus-scan method capable of full-scanning the logical volume of a SUTOSEN PC with high frequency while limiting the number of virus-scan devices. The computer system includes a primary volume storing data from a personal computer, a snapshot volume storing the status of the primary volume at a given point in time, and a save destination volume storing an updated memory area within the primary volume as information on an updated block address reflected in a bitmap. The updated block address corresponds to a memory area within the primary volume. The computer system detects only an updated file in the primary volume from the snapshot volume and the save destination volume, creates an updated volume for storing a relevant updated file, and thereby executes a virus-scan on the updated volume.

Abstract: A secure Voice-Over-IP (VOIP), video and data network functionality in a single, small size deployable case, for a remote user. While capable of secure communications, the disclosed system also provides communication capability (VOIP, video and/or data) in a non-secure manner if desired. Most importantly, bulk encrypted (i.e., secure) data may be routed over a public network, e.g., the Internet.

Abstract: A system and method for automatically selecting a procedure for resetting an authentication data, such as a password, a PIN, a secret key, or a private key, according to the value of the user data protected by the authentication data and/or the likelihood for the user to forget or otherwise lose the authentication data. The user's preference is also considered in selecting the procedure for resetting the authentication data.

Abstract: A method for protecting traffic in a radio access network connected to at least two core networks. The method includes maintaining a core-network-specific authentication protocol and a radio-bearer-specific ciphering process, and generating, for each ciphering process, a count parameter including a cyclical sequence number and a hyperframe number (HFN) which is incremented each time the cyclical sequence number completes one cycle. For each core network or authentication protocol, a first radio bearer of a session is initialized with a HFN exceeding the highest HFN used during the previous session. When a new radio bearer is established, the mobile station selects the highest HFN used during the session for the core network in question, increments it and uses it for initializing the count parameter for the new radio bearer. At the end of a session, the mobile station stores at least part of the highest HFN used during the session.

Abstract: A system and method for assessing risks to computer network is provided. The system includes a first module assesses a human factor related to a risk to the computer network. A second module assesses a remediation to the computer network, and a third module is operable to assess a life cycle of an asset on the computer network. A fourth module assesses a type of the asset used by the computer network.
