Leakage-Resilient Storageyed) scheme for encoding messages, and can be viewed as a generalization of the . (AONT, Rivest 1997). The standard definition of AONT requires that it should be hard to reconstruct a message . if not all the bits of its encoding .(.) are known. LRS is defined more generally, with respect to a class

Searching Keywords with Wildcards on Encrypted Datat. The decryption key is also derived from such a vector, but this one is also allowed to have “?” (or wildcard) entries. Decryption is possible as long as these tuples agree on every position except where a “?” occurs..These schemes are useful for a variety of applications: they can be used as a bu

Threshold Attribute-Based Signcryptiony, and authenticity of a message in addition to attesting the attributes of the sender. Such a property is useful in applications such as electronic card, digital prescription carrier devices, secure and authentic email service, etc. Our scheme relies on the intractability of the hashed modified dec

Efficiency-Improved Fully Simulatable Adaptive OT under the DDH Assumptionodel. However, Green and Hohenberger pointed out that the communication cost of each transfer phase is .(.), where . is the number of the sender’s messages. In this paper, we show that the cost can be reduced to .(1) by utilizing a verifiable shuffle protocol.

Improved Primitives for Secure Multiparty Integer Computationhigher-level protocols offer integer truncation and comparison, which are typically the main performance bottlenecks in complex applications. We present techniques and building blocks that allow to improve the efficiency of these protocols, in order to meet the performance requirements of a broader

A New Security Model for Authenticated Key Agreementls. We discuss security shades in the (e)CK models, and some practical attacks unconsidered in (e)CK–security arguments. We propose a strong security model which encompasses the eCK one. We also propose a new protocol, called Strengthened MQV (SMQV), which in addition to provide the same efficiency

Authenticated Key Agreement with Key Re-use in the Short Authenticated Strings Modelenticates arbitrarily long messages sent over insecure channels as long as the sender and the receiver can additionally send a very short, e.g. 20 bit, . message to each other. The main practical application of a SAS-MA protocol is Authenticated Key Agreement (AKA) in this communication model, i.e.

GLOOM

Kleptography from Standard Assumptions and Applicationsms and their applications. A prototypical example is a cryptosystem (or a protocol message employing a cryptosystem) where a cryptogram field (e.g., a public key, an encrypted message, a signature value) hosts an “inner cryptographic field” that is invisible (in the sense of indistinguishability) to
