Secure and efficient two-party ECDSA signature scheme by Jing WANG, Libing WU, Min LUO, Debiao HE

“…To solve the easy disclosure of signature private key and excessive concentration of signature rights, a secure and efficient two-party ECDSA signature scheme was proposed for the blockchain based network trading systems.By pre-computing one-time pad Beaver’s triple, and utilizing the Beaver’s triple based secure two-party multiplication technology, some computationally intensive homomorphic encryption operations and oblivious transfer operations with high communication overhead were effectively avoided, and thereby an efficient two-party ECDSA signing was realized, which could ensure that the two signing parties output valid ECDSA signature without reconstructing the complete private key.The proposed scheme was proved to be provably secure under the hybrid model of the universally composable framework.Theoretical analysis and simulation results demonstrate that the proposed scheme has significant advantages in terms of signing efficiency and bandwidth requirements when compared with the existing two two-party ECDSA signature schemes.…”

Shakespeare à l’écran : Makibefo d’Alexander Abela, un exemple extrême d’appropriation culturelle by Anne-Marie Costantini-Cornède

“…By transposing the play Macbeth to an unusual context, a poor fishermen’s village lost at the other end of the world, the filmmaker means to enhance its mythic and universal dimension. He resorts to various narrative and aesthetic strategies such as plot displacements, character suppressions or dialogue simplifications as well as ample and systematic use of cinematic rhetoric (camera movements, framing and angle shot effects or light contrasts), which helps create a filmic mode. …”

Las destrezas en el examen físico by Alfredo Espinosa Brito

“…En el campo de la atención médica hay una tendencia universal nada favorable en la actualidad, que nos atañe muy de cerca a los profesores del área clínica, y es la de minimizar el valor de la realización del examen físico del enfermo -e incluso llegar a obviarlo en muchos casos-, por confiar de manera excesiva en un interrogatorio somero y, especialmente, en los modernos medios complementarios de diagnóstico para conducir el acto médico y para la toma de decisiones en cada caso. …”

Chaining ＆ counter-based block cipher mode for authentication by HUANG Yu-hua1, HU Ai-qun2, WANG Jian-dong1

“…For raising the operation efficiency of block cipher algorithms,a fast authentication mode based on chaining ＆ counter（CCTR） was put forward;and its security was proved.Its speed was about 30% faster than that of authentication modes in common use（for example,CBC-MAC）.The dependence test results accord with the demands.The CCTR mode is complete;its degree of avalanche effect is about 0.999 3;its degree of strict avalanche criterion is 0.992 or so.The frequency test results indicate that the output generated by the CCTR mode had uniformity.The binary matrix rank,Run,spectral,non-overlapping template matching,overlapping template matching,Maurer’s universal statistical test,Lempel-Ziv compression,linear complexity,serial,approximate entropy,cumulative sums,random excursions and random excursions variant tests results fulfilled the requirements all.Therefore,the CCTR mode has good pseudo-randomness,which the security of CCTR mode is verified by way of statistical evaluation.…”

Extensible hierarchical codec semantic communication system by Yuyuan ZHANG, Haitao ZHAO, Jibo WEI, Kuo CAO, Yichi ZHANG, Peng LUO, Yueling LIU, Kai MEI

“…Aiming at the problem that most current researches on text semantic communication mainly rely on simulation system for theoretical verification, an extensible hierarchical semantic communication system was proposed by taking advantage of the separation of hierarchical encoding and decoding architecture in semantic level and grammatical level.The system was compatible with the reliable communication technology under the framework of Shannon information through the mode of semantic and syntactic separation, and realized the nested combination of semantic communication and traditional communication.Furthermore, a universal and extensible verification system was built based on the software radio platform to verify the proposed semantic communication system architecture.The verification system took semantic communication software platform as the driving core of hardware drive and algorithm call, integrated the whole process of signal generation, information transmission, data acquisition, decoding and evaluation at the receiving end, and could be further extended for semantic and syntactic level.Finally, the text semantic communication was tested based on this verification system, which verified that it had higher validity and reliability than the traditional communication mode.…”

Another Life (1972), de Derek Walcott, ou les lettres du mal-voyant by Kerry-Jane Wallart

“…The purpose of this article is to show to what extent painting is not described by Derek Walcott as a failure but rather as the means of a poetical incarnation through a gesture of diversion from the visible universe. These verses of an unfit seer quickly veer towards a tribute paid to a genre, painting, which is not so much opposed to poetry as made to echo it through graphics which, in Rimbaldian fashion, take on colours.…”
