ON TWE RENlARRABLE DISTRIBUTIONS OF MAXIPMA OF SOME FRAGMENTS OF THE STANI)ARD REFLECTING RANDOM WALK AND BROWNIAN MOTION
Standard random walk standard Brownian motion excursion meander comeander infinite divisibility
2009/9/18
In this paper, we consider some distributions of maxima
of excursions and related variables for standard random walk and
Brownian motion. We discuss the infinite divisibility properties of
these di...

2009/9/15
阿德•申克在1968年法国格勒诺布尔冬季奥运会上获得1500米速滑银牌，随后几年，申克的成绩提高得很快，到1972年日本札幌冬季奥运会时，他已经是1500米 、5000米和10000米三个速滑项目的世界纪录保持者。1972年日本札幌冬季奥运会上，在一个暴风雪的天气中，申克以4.57秒的优势获得5000米速滑金牌，随后500米速滑中他名列第34，但他接下来包揽了两外两个速滑项目的金牌：1...
Salvaging Merkle-Damg°ard for Practical Applications
hash functions random oracle model indifferentiability framework
2009/6/12
Many cryptographic applications of hash functions are analyzed in the random oracle model. Unfortunately, most
concrete hash functions, including the SHA family, use the iterative (strengthened) Merk...
Davies-Meyer Merkle-Damg˚ard Revisited:Variants of Indifferentiability and Random Oracles
Merkle-Damgard construction Davies-Meyer mode indifferentiability
2009/6/11
In this paper, we succeed in analyzing practical cryptosystems that employ the Davies-
Meyer Merkle-Damg˚ard hash function DM-MDE with ideal cipher E by using two approaches: indifferentiability...
How to Prove the Security of Practical Cryptosystems with Merkle-Damg˚ard Hashing by Adopting Indifferentiability
Indifferentiability theory Merkle-Damgard hash function Random Oracle
2009/6/11
In this paper, we show that major cryptosystems such as FDH, OAEP, and RSA-KEM are
secure under a hash function MDh with Merkle-Damg˚ard (MD) construction that uses a random oracle
compression ...
On The Security of The ElGamal Encryption Scheme and Damg°ard’s Variant
ElGamal encryption Damg°ard’s ElGamal variant security proof
2009/6/4
In this paper, we discuss the security of the ElGamal encryption scheme and its variant by
Damg°ard. For the ElGamal encryption, we show that (1) under the generalized knowledge-of-exponent
assumpti...
Domain Extender for Collision Resistant Hash Functions: Improving Upon Merkle-Damg°ard Iteration
hash function compression function composition principle
2009/4/9
We study the problem of securely extending the domain of a collision resistant compression function.
A new construction based on directed acyclic graphs is described. This generalizes the usual itera...
We provide a new security proof for a variant of ElGamal proposed by Damg°ard,
showing that it is secure against non-adaptive chosen ciphertext. Unlike previous
security proofs for this cryptosystem...

The paper discusses the security of compression function and
hash function with Merkle-Damgºard construction and provides the com-
plexity bound of ¯nding a collision and primage of hash f...
