WebAug 16, 2003 · Abstract: In this paper we introduce a novel type of cryptographic scheme, which enables any pair of users to communicate securely and to verify each other’s signatures without exchanging private or public keys, without keeping key directories, and without using the services of a third party. The scheme assumes the existence of trusted … WebHardness of learning from cryptographic assumptions. Among several previous works [34, 35] which leverage cryptographic assumptions to establish hardness of improper learning, most relevant to our results is the seminal work of Klivans and Sherstov [36] whose hardness results are also based on SVP.

The mission of theoretical cryptography is to define and construct provably secure cryptographic protocols and schemes. Without proofs of security, cryptographic con- structs offer no guarantees … WebIn this paper, we propose such a classication and review recently suggested assumptions in this light.

We first construct a protocol for information theoretic secure positioning in this model. To our knowledge, this is the first protocol which is secure even against collusion attacks. Although secure positioning is an important step, the full power of position based cryptography can only be realized if we achieve key … WebApr 14, 2024 · The security strength of a random number generator depends on the unpredictability of its outputs. This unpredictability can be measured in terms of entropy, which the NIST SP 800-90 series measures using min-entropy. A full-entropy bitstring has an amount of entropy equal to its length. Full-entropy bitstrings are important for … iri official
