    Abstract: In some embodiments, a multi-port queueing cache includes a plurality of first ports, a plurality of second ports, a plurality of request handlers respectively coupled to the plurality of first ports, a cache storage unit coupled to the plurality of second ports, a reserve interface configured to exchange at least one address and at least one reserved cache line number, and a request interface configured to exchange the at least one reserved cache line number and at least one data. The reserve interface and the request interface are disposed between the plurality of request handlers and the cache storage unit. The cache storage unit includes a plurality of cache lines configured to store the plurality of data. The cache storage unit is configured to output a portion of the plurality of addresses, and receive a portion of the plurality of data corresponding to the portion of the plurality of addresses.

    Abstract: A random number generator includes a first oscillator configured to output a first oscillating signal having a first frequency. A second oscillator is configured to output a second oscillating signal having a second frequency different from the first frequency. A sampling unit is configured to receive the first and second oscillating signals. The sampling unit is configured to generate at least one entropy source by combining the received first and second oscillating signals. The sampling unit is configured to generate a random bit corresponding to the generated entropy source using a third oscillating signal. A third oscillator & control unit is configured to control the first and second oscillators and to generate the third oscillating signal. A frequency of the third oscillating signal is lower than the first and second frequencies.

    Abstract: A method for encryption, decryption, or encryption and decryption of data in a crypto device having at least one crypto core may include: generating a tweak value corresponding to block data, which is placed at a random position from which the encryption, decryption, or encryption and decryption starts, from among sequential block data; and/or performing the encryption, decryption, or encryption and decryption from the block data using the tweak value. A method for encryption, decryption, or encryption and decryption of block data may include: generating a tweak value corresponding to the block data at a random position; and/or performing the encryption, decryption, or encryption and decryption of the block data using the tweak value.
