Efficient Batch Verification for UP

, 2018
Consider a setting in which a prover wants to convince a verifier of the correctness of k NP statements. For example, the prover wants to convince the verifier that k given integers N_1,...,N_k are all RSA moduli (i.e., products of equal length primes).

Fast Batch Verification of Multiple Signatures [PDF]

, 2007
We propose an efficient batch verification of multiple signatures generated by different signers as well as a single signer. We first introduce a method to generate width-w Non-Adjacent Forms (w-NAFs) uniformly. We then propose a batch verification algorithm of exponentiations using w-NAF exponents, and apply this to batch verification for the modified

Support Neighbor Loss for Person Re-Identification

, 2018
Person re-identification (re-ID) has recently been tremendously boosted due to the advancement of deep convolutional neural networks (CNN). The majority of deep re-ID methods focus on designing new CNN architectures, while less attention is paid on ...

Prosodic-Enhanced Siamese Convolutional Neural Networks for Cross-Device Text-Independent Speaker Verification

, 2018
In this paper a novel cross-device text-independent speaker verification architecture is proposed. Majority of the state-of-the-art deep architectures that are used for speaker verification tasks consider Mel-frequency cepstral coefficients. In contrast,

Batch Computations Revisited: Combining Key Computations and Batch Verifications [PDF]

, 2011
We consider the effect of combining the key computation step in particular key agreement protocols, such as ECMQV and static-DH, with verifying particular elliptic curve equations, such as those related to ECDSA signature verification. In particular, we show that one can securely combine ECDSA signature verification and ECMQV and static-ECDH key ...
