Consider the RSA public key cryptosystem with the parameters N = pq, q < p < 2q, public encryption exponent e and private decryption exponent d. In this paper, cryptanalysis of RSA is studied given that some amount of the Most Significant Bits (MSBs) of d is exposed. In Eurocrypt 2005, a lattice based attack on this problem was proposed by Ernst, Jochemsz, May and de Weger. In this paper, we pr...

With nine-axis sensing systems in 5G smartphones, mobile power consumption has become increasingly important, and ultra-low-power (ULP) sensor circuits can decrease to tens of microwatts. This paper presents an innovative successive approximation register analog-to-digital converter, which comprises fine (three most significant bits (MSBs) plus course conversion (11 least (LSBs)) capacitive dig...

Two’s complement signal representation is widely used in the implementation of arithmetic operations. However, it is well-known that its sign-extension can cause undesirable signal transitions in the MSBs of a data-path circuit. We propose a novel technique to reduce the signal transitions due to sign-extension while retaining the simplicity of the two’s complement arithmetic operations. The ke...

We consider the problem of recovering $n$ i.i.d samples from a zero mean multivariate Gaussian distribution with an unknown covariance matrix, their modulo wrapped measurements, i.e., measurement where each coordinate is reduced $\Delta$, for some $\Delta>0$. For this setup, which motivated by quantization and analog-to-digital conversion, we develop low-complexity iterative decoding algorithm....

This paper presents a 12-bit 150-MHz current steering DAC with hierarchical symmetrical switching sequence that compensates gradient errors. The circuit of the DAC employs segmented architecture; the least significant bits (LSBs) steer a binary weighted array, while the most significant bits (MSBs) are thermometer decoded and steer a unary array. The measured differential nonlinearity and integ...

Several morphological changes of synapses have been reported to be associated with the induction of long-term potentiation (LTP) in the CA1 hippocampus, including an transient increase in the proportion of synapses with perforated postsynaptic densities (PSDs) and a later occurrence of multiple spine boutons (MSBs) in which the two spines arise from the same dendrite. To investigate the functio...

In this paper, an error-correction code (ECC)-enabled memory design with selective bit hardening is proposed for approximate data storage. Approximate suitable error-tolerant applications, and can achieve low-power goals within targeted quality. Our offers approximately 90% power savings compared to traditional memory, without compromising perceived To the best of our knowledge, combining ECC a...
