    Abstract: An acoustic tracking system is provided that includes receivers that detect first acoustic signals from a first set of transmitters disposed on a digital pen and second acoustic signals from a second set of transmitters disposed on a base station. The acoustic tracking system also includes a processing component that defines a two-dimensional plane on which the base station lies and determines a three-dimensional position of the digital pen relative to the base station. The processing component projects the three-dimensional position of the digital pen onto the two-dimensional plane and records, based on the projected three-dimensional position, the three-dimensional position of the digital pen relative to the base station, where the recorded three-dimensional position of the digital pen represents an object representative of movement of the digital pen.

    Abstract: Disclosed is an apparatus and method for encrypting plaintext data. The method includes: receiving at least one plaintext data input; applying a Nonce through a function to the at least one plaintext data input to create Nonced plaintext data outputs and/or to intermediate values of a portion of an encryption function applied to the at least one plaintext data input to create intermediate Nonced data outputs; and applying the encryption function to at least one of the Nonced plaintext data outputs and/or the intermediate Nonced data outputs to create encrypted output data. The encrypted output data is then transmitted to memory.

    Abstract: One feature pertains to a content accessing device for securing content. The content accessing device is provisioned with a cryptographic algorithm, and generates a symmetric key also known to a content storage device. The content accessing device sends a first authentication challenge to the content storage device, where the first authentication challenge is based on the cryptographic algorithm and the symmetric key. The content accessing device receives a second authentication challenge from the content storage device in response to sending the first authentication challenge, and determines whether the first authentication challenge is different from the second authentication challenge. If the second authentication challenge is different from the first authentication challenge the content accessing device sends a first response to the content storage device in response to the second authentication challenge.

    Abstract: In certain aspects of the disclosure, an apparatus, comprises a first memory having a plurality of bits. Each bit of the plurality of bits of the first memory is associated with a region of a second memory, and each bit indicates whether the associated region of the second memory is to be integrity-protected. The first memory further stores a first minimum set of data necessary for integrity protection (MSD) of an associated first integrity protection tree when a first bit of the plurality of bits is set to a value indicating that the first associated region of the second memory is to be integrity-protected. Regions of the second memory that are integrity-protected may be non-contiguous, and may be adjusted during run-time.

    Abstract: One feature pertains to an electronic device that includes a memory circuit and a processing circuit. The processing circuit computes a scalar multiplication output Z where Z=k·P by receiving an input multiplier k and a base P, and adds a modifier s to the input multiplier k to generate k′. The processing circuit also computes an intermediate scalar multiplication output Z′ where Z′=k′·P by using a digit expansion of k′ that includes a sequence of digits ki belonging to a digit set D. Additionally, the processing circuit subtracts s·P from Z′ to obtain the scalar multiplication output Z if k′ is odd or subtracts (s+1)·P from Z′ to obtain the scalar multiplication output Z if k′ is even. The scalar multiplier output Z may be used in a cryptographic security algorithm to secure data.

    Abstract translation: 一个特征涉及包括存储器电路和处理电路的电子设备。 处理电路通过接收输入乘法器k和基数P来计算标量乘法输出Z，其中Z = k·P，并将修正符s加到输入乘法器k以产生k'。 处理电路还通过使用包括属于数字集D的数位ki的序列的k'的数字展开来计算Z'= k'·P的中间标量乘法输出Z'。另外，处理电路减去s· P从Z'获得标量乘法输出Z，如果k'为奇数，则从Z'中减去（s + 1）·P，以获得如果k'为偶数的标量乘法输出Z。 标量乘法器输出Z可用于加密安全算法中以保护数据。
