摘要： Methods and apparatuses for addressing open space noise are disclosed. In one example, a method for masking open space noise includes optimizing a recorded naturally occurring sound signal. The method also includes outputting the optimized recorded naturally occurring sound signal from a plurality of speakers distributed in the open space. Further, the method includes displaying a natural system complementing the optimized recorded naturally occurring sound signal.

摘要： A radio transmitter adjusts the spectral, amplitude, and/or phase characteristics of its transmissions to defeat radio fingerprinting identification without destroying the content of the transmissions. The transmitter determines a threshold of signal distortion that impedes RF fingerprint identification while providing an acceptable amount of degradation to data transmissions and then synthesizes a distortion of its unique RF fingerprint to impede identification. The transmitter may create RF fingerprint “personalities” to be paired with different radio protocol behaviors and subscriber terminal identification codes (e.g., MAC addresses or SMSIs) for generating different radio identities.

摘要： Circuits, methods, and systems are provided for securing an integrated circuit device against Differential Power Analysis (DPA) attacks. Plaintext (e.g., configuration data for a programmable device) may be encrypted in an encryption system using a cryptographic algorithm. Ciphertext may be decrypted in a decryption system using the cryptographic algorithm. The encryption and/or decryption systems may obfuscate the plaintext, the ciphertext, and/or the substitution tables used by the cryptographic algorithm. The encryption and/or decryption systems may also generate cryptographic key schedules by using different keys for encrypting/decrypting different blocks and/or by expanding round keys between encryption/decryption blocks. These techniques may help mitigate or altogether eliminate the vulnerability of cryptographic elements revealing power consumption information to learn the value of secret information, e.g., through DPA.

摘要： Methods, apparatus, systems, and articles of manufacture to implement a third-order signal scrambler are disclosed. An example apparatus includes a controlled scramble generator to generate a controlled random sequence based on one or more subcarriers and a random pulse sequence, the random pulse sequence based on an output of a random number generator processed by a multi-order sinusoidal noise function. The example apparatus further includes a sequence modifier to form an output sequence by combining a source sequence with the controlled random sequence, the controlled random sequence to modify a characteristic of the source sequence in a frequency domain.

摘要： A system and method for improving performance while transferring encrypted data in an input/output (I/O) operation are provided. The method includes receiving a block of data. The method also includes dividing the block of data into a plurality of sub-blocks of data. The method further includes performing a first operation on a first sub-block. The method also includes performing a second operation on a second sub-block at substantially the same time as performing the first operation on the first sub-block. The method still further includes reassembling the plurality of sub-blocks into the block of data.
