Abstract: A method and system for encrypting and verifying the integrity of a message using a three-phase encryption process is provided. A source having a secret master key that is shared with a target receives the message and generates a random number. The source then generates: a first set of intermediate values from the message and the random number; a second set of intermediate values from the first set of values; and a cipher text from the second set of values. At the three phases, the values are generated using the encryption function of a block cipher encryption/decryption algorithm. The random number and the cipher text are transmitted to the target, which decrypts the cipher text by reversing the encryption process. The target verifies the integrity of the message by comparing the received random number with the random number extracted from the decrypted cipher text.

Abstract: A cummerbund belt assembly for retaining a cummerbund in a preferred position includes a cummerbund is wearable around a waist of a user to enhance the appearance of formal dress. A plurality of couplers is each coupled to and extends downwardly from the cummerbund. Each of the couplers is positioned at strategic locations along the cummerbund such that each of the couplers is aligned with a respective plurality of suspender buttons in the trousers. Moreover, each of the couplers releasably engages the respective suspender button to inhibit the cummerbund from riding upwardly on the user's waist when the cummerbund and the trousers are worn.

Abstract: A system and method for determining a desired portion of a subject to receive a radiation dose includes iteratively chooses weight vectors to run to gradually build up a Pareto surface (PS). By examining the current points that have been found on the PS along with the weights used to produce those points, a new weight vector is produced and run. This process is repeated until a geometric stop tolerance is met.

Abstract: A processing unit includes a read-only encryption key. Loader code image is loaded into system memory from non-volatile storage. Loader code image includes a prefix value and a suffix value. The prefix value is combined with the master key from the processing unit to create a random value that is the seed for a hashing algorithm. The hashing algorithm uses the seed value with a signature formed from the blocks of code to form a result. During the hashing algorithm, intermediate key values are generated and stored in a memory area inaccessible by the user. The intermediate key values are used by the loader code after the loader has been authenticated and loaded. The loader combines one or more of the intermediate key values with prefix and suffix values that correspond to other software modules to authenticate the software, using a hashing algorithm, and load the software upon authentication.

Abstract: A processing unit includes a read-only encryption key. Software is loaded into a system memory area from a non-volatile storage device. Software code image that resides in the system storage area includes a prefix value and a suffix value. The prefix value is combined with the master key from the processing unit to create a random value that is the seed for a hashing algorithm. The hashing algorithm uses the seed value with a signature formed from the blocks of code to form a result. Finally, after the last block has been processed, a final result remains. The suffix value is combined with the master key, this hash result is compared with the result that was created using the hashing algorithm on the code. If the two results match, the code is authenticated and is executed. If the results do not match, the code is not loaded.
