摘要： A system for providing high security for data stored in memories in computer systems is disclosed. A different encryption key is used for every memory location, and a write counter hides rewriting of the same data to a given location. As a result, the data for every read or write transaction between the microprocessor and the memory is encrypted differently for each transaction for each address, thereby providing a high level of security for the data stored.

摘要： A method of protecting information in a data storage device is provided. The method includes receiving, in the data storage device, encrypted data via a host computer in which the data storage device is employed. The encrypted data is then decrypted, and re-encrypted, in the data storage device, either before storage or just before data is transferred back to the host computer. The decryption and re-encryption (transcription) is performed substantially independently of the host computer. In addition, a data storage device, readable by a computer system, for implementing the above method for protecting information is provided.

摘要： An apparatus, system and method for retaining the maximum speed of flip-flop metastability based random number generators includes a fixed delay unit having an input for receiving a common signal from a digital signal generator, and a variable delay unit having an input also for receiving the common signal from the digital signal generator. Each of the delay units is attached to the input of a respective logic gate. A frequency measurement of the occurrences of metastability, which is the speed of the random bit generation and delay tuning module 312 receives an output of one of the first NAND gates, checks the frequency of random number bit generation and updates the variable delay unit to according to predetermined criteria to tune the delay so as to maximize the speed of the random bit generation. An algorithm is used to determine whether the optimum delay is equal to, smaller or larger than the delay used to achieve the measured frequency.

摘要： Further increases in the difficulty of importing to a secure domain digital content including watermarks which impose a degree of difficulty on illicit importing to the secure domain of the digital content is disclosed. Further increases in the degree of difficulty are necessary because the degree of difficulty associated with the watermarks is capable of being illicitly overcome by dividing the digital content being imported into segments that are so short that the watermarks cannot be reliably detected. In a recorder, recording is prevented by determining that adjacent activations of start and stop keys are such that the digital content has been so divided. In a playback unit, playback is prevented by determining that recorded sections are so short that the watermarks therein cannot be reliably detected.

摘要： A network of M devices such that M31 and methods for devices to join and leave the network. Each device of the network has a real or virtual token counter that stores a token count of not less than zero. An equation M+S = K must be satisfied. S denotes the number of tokens in the network and is numerically equal to a summation of the token counts over the M devices. K is a characteristic integer constant of the network having a value of at least 2 and is established upon creation of the network. Each device has a controller for connecting and communicating with at least one other device when M>1. The network has network rules, comprising a joining rule for effectuating a non-network device joining the network and a leaving rule for effectuating a network device leaving the network.
