Information and Communications Security : First International Conference ICIS97 Beijing China November 11 14 1997 Proceedings This book constitutes the refereed proceedings of the First International Conference on Information and Communication Security ICICS 97 held in Beijing China in November 1997. The 37 revised full papers presented were selected from a total of 87 submissions. Also included are 11 short papers. The book is divided in sections on theoretical foundations of security secret sharing network security authentication and identification Boolean functions and stream ciphers security evaluation signatures public key systems cryptanalysis of public key systems subliminal channels key recovery intellectual property protection protocols and electronic commerce Minimizing the use of random oracles in authenticated encryption schemes Zero knowledge proofs of decision power: New protocols and optimal round complexity Computational learning theoreitc cryptanalysis of language theoretic cryptosystems A language for specifying sequences of authorization transformations and its applications On the decomposition constructions for perfect secret sharing schemes Traceable visual cryptography Remarks on the multiple assignment secret sharing scheme Secret sharing in hierarchical groups Stateless connections Design of a security platform for CORBA based application Secure document management and distribution in an open network environment A 2 code = Affine resolvable + BIBD Multisender authentication systems with unconditional security Proposal of user identification scheme using mouse An effective genetic algorithm for finding highly nonlinear boolean functions Duality of Boolean functions and its cryptographic significance Construction of correlation immune Boolean functions An improved key stream generator based on the programmable cellular automata A trust policy framework Critical analysis of security in voice hiding techniques Two efficient RSA multisignature schemes Proxy signatures revisited Related key cryptanalysis of 3 WAY Biham DES CAST DES X NewDES RC2 and TEA A multiplication addition structure against differential attack On strict estimation method of provable security against differential and linear cryptanalysis Improved fast software implementation of block ciphers (Extended abstract) Security comments on the Hwang Chen algebraic code cryptosystem Efficient elliptic curve exponentiation Efficient construction of secure hyperelliptic discrete logarithm problems A new and optimal chosen message attack on RSA type cryptosystems On weak RSA keys produced from pretty good privacy Self synchronized message randomization methods for subliminal channels Hiding the hidden: A software system for concealing ciphertext as innocuous text Digital signature and public key cryptosystem in a prime order subgroup of Z n * Trapdoor one way permutations and multivariate polynomials Asymmetric cryptography with S Boxes Is it easier than expected to design efficient asymmetric cryptosystems On the powerline system Making unfair a “Fair” blind signature scheme Enforcing traceability in software Publicly verifiable partial key escrow A secure code for recipient watermarking against conspiracy attacks by all users Protocols for Issuing public key certificates over the Internet Distributed cryptographic function application protocols Fault tolerant anonymous channel An Implementable scheme for secure delegation of computing and data Electronic commerce with secure intelligent trade agents Efficient scalable fair cash with off line extortion prevention An anonymous and undeniable payment scheme
