    On the Indifferentiable Hash Functions in the Multi-Stage Security Games

    It had been widely believed that the indifferentiability framework ensures composition in any security game. However, Ristenpart, Shacham, and Shrimpton (EUROCRYPT 2011) demonstrated that for some multi-stage security, there exists a cryptosystem which is secure in the Random Oracle (RO) model but is broken when some indifferentiable hash function is...

    Achieving Short Ciphertexts or Short Secret-Keys for Adaptively Secure General Inner-Product Encryption

    In this paper, the authors present two Non-zero Inner-Product Encryption (NIPE) schemes that are adaptively secure under a standard assumption, the Decisional LINear (DLIN) assumption, in the standard model. One of the proposed NIPE schemes features constant-size ciphertexts and the other features constant-size secret-keys. Their NIPE schemes imply an Identity-Based...

    Decentralized Attribute-Based Signatures

    In this paper, the authors present the first Decentralized Multi-Authority Attribute-Based Signature (DMA-ABS) scheme, in which no central authority and no trusted setup are required. The proposed DMA-ABS scheme for general (non-monotone) predicates is fully secure (adaptive-predicate unforgeable and perfect private) under a standard assumption, the Decisional LINear (DLIN) assumption,...

    Efficient Attribute-Based Signatures for Non-Monotone Predicates in the Standard Model

    This paper presents a fully secure (adaptive-predicate unforgeable and private) Attribute-Based Signature (ABS) scheme in the standard model. The security of the proposed ABS scheme is proven under standard assumptions, the Decisional LINear (DLIN) assumption and the existence of Collision Resistant (CR) hash functions. The admissible predicates of the proposed...

    Intermediate View Generation for Perceived Depth Adjustment of Stereo Video

    There is significant industry activity on delivery of 3D video to the home. It is expected that 3D capable devices will be able to provide consumers with the ability to adjust the depth perceived for stereo content. This paper provides an overview of related techniques and evaluates the effectiveness of...

    Fully Secure Functional Encryption With General Relations From the Decisional Linear Assumption

    This paper presents a fully secure functional encryption scheme for a wide class of relations, that are specified by non-monotone access structures combined with inner-product relations. The security is proven under a standard assumption, the decisional linear (DLIN) assumption, in the standard model. The proposed functional encryption scheme covers, as...

    Dual Power Multiple Access With Multipacket Reception Using Local CSI

    Contention-based multiple access is a crucial component of many wireless systems. Multiple-Packet Reception (MPR) schemes that use interference cancellation technique to receive and decode multiple packets that arrive simultaneously are known to be very efficient. However, the MPR schemes proposed in the literature require complex receivers capable of performing advanced...

    Regressed Importance Sampling on Manifolds for Efficient Object Tracking

    In this paper, a new integrated particle filter is proposed for video object tracking. After particles are generated by importance sampling, each particle is regressed on the transformation space where the mapping function is learned offline by regression on pose manifold using Lie algebra, leading to a more effective allocation...
