Sugarcane Selection for Sucrose and Tonnage Using Economic Criteria by José Alvarez, Chris W. Deren, Barry Glaz

“… The objectives of this document (mainly based on Alvarez, et al., 2003) are to illustrate the use of an economic index in selecting clones that are somewhat ambiguous in merit (mid-to-low rankings in TCA or SC) and to show how the relationship between TCA and SC can differ when viewed from an economic, rather than a biological, perspective. …”

Saturation cryptanalysis of CLEFIA by WANG Wei1, WANG Xiao-yun2

“…The saturation attack on a novel block cipher CLEFIA,which was proposed in FSE 2007,was reevaluated.The flaws in Shirai et al’s 8 round distinguishers were pointed out and corrected.In order to reduce the number of guessed subkeys,the attack utilized the movement of the whitening key to combine it with subkey,and explored a di-vide-and-conquer strategy.The partial sum technique was adopted to reduce the time complexity.As a result,the satura-tion attack can be extended from 10 round variant without key whitenings to 11 round CLEFIA-128/192/256,and is ap-plicable to 12 round CLEFIA-192/256 and 13 round CLEFIA-256.…”

Certificateless generalized signcryption scheme in the standard model by Shu-fen NIU, Ling NIU, Cai-fen WANG, Ya-hong LI

“…In 2010,Liu,et al.proposed a certificateless signcryption scheme in the standard model,but many analyses revealed that Liu's scheme was insecure in fact.To overcome the disadvantages,the scheme was improved and a certificateless generalized signcryption scheme was constructed.In addition,a formal security model for the proposed scheme against the malicious-but-passive KGC attacks was introduced.Furthermore,the proposed scheme was proven to be secure under the decisional bilinear Diffie-Hellman and the computational Diffie-Hellman intractability assumptions in the standard model.Numerical results illustrate that the proposed algorithm is efficient.…”
