    摘要： The present invention discloses a method and device of generating asymmetrical key pair (public key and private key) based on user identity. Key Management Center (KMC) generates public/private key calculating base, and publish the public key calculating base. Based on identity provided by a user, a private key is calculated and provided to the user. Any user can calculate other user's public key based on other user's identity and the published public key calculating base. Thus, when obtaining the public key of the communicating party, no third party CA certificate is needed, and no maintenance of mass parameters associated with users are needed.

    摘要： A technique for MRI or the like employs optimized orthogonal gradients. For a device having a peak physical magnetic field gradient strength G0, the gradients are optimized if, in physical space, one gradient has a value −0.5G0 while the two gradients orthogonal thereto have the value G0. That is equivalent to an optimized orthogonal gradient space in which one gradient has a value 1.5G0 while the two gradients orthogonal thereto have the value zero. The gradients are cycled over a sequence of six gradient pulses to provide enough data to calculate the diffusion tensor.

    摘要： The present disclosure is directed to systems and methods for detecting side-channel exploit attacks such as Spectre and Meltdown. Performance monitoring circuitry includes first counter circuitry to monitor CPU cache misses and second counter circuitry to monitor DTLB load misses. Upon detecting an excessive number of cache misses and/or load misses, the performance monitoring circuitry transfers the first and second counter circuitry data to control circuitry. The control circuitry determines a CPU cache miss to DTLB load miss ratio for each of a plurality of temporal intervals. The control circuitry the identifies, determines, and/or detects a pattern or trend in the CPU cache miss to DTLB load miss ratio. Upon detecting a deviation from the identified CPU cache miss to DTLB load miss ratio pattern or trend indicative of a potential side-channel exploit attack, the control circuitry generates an output to alert a system user or system administrator.
