Selected Areas in Cryptography [recurso electrónico] : 18th International Workshop, SAC 2011, Toronto, ON, Canada, August 11-12, 2011, Revised Selected Papers

Annotation This book constitutes the thoroughly refereed post-conference proceedings of the 18th Annual International Workshop on Selected Areas in Cryptography, SAC 2011, held in Toronto, Canada in August 2011. The 23 revised full papers presented together with 2 invited papers were carefully reviewed and selected from 92 submissions. The papers are organized in topical sections on cryptanalysis of hash functions, security in clouds, bits and randomness, cryptanalysis of ciphers, cryptanalysis of public-key crypthography, cipher implementation, new designs and mathematical aspects of applied cryptography Front Matter....Pages - Very Compact Hardware Implementations of the Blockcipher CLEFIA....Pages 278-292 Cryptographic Analysis of All 4 × 4-Bit S-Boxes....Pages 118-133 The Cryptographic Power of Random Selection....Pages 134-150 Proof of Empirical RC4 Biases and New Key Correlations....Pages 151-168 Another Look at Tightness....Pages 293-319 Combined Differential and Linear Cryptanalysis of Reduced-Round PRINTcipher ....Pages 169-184 Practical Attack on the Full MMB Block Cipher....Pages 185-199 Conditional Differential Cryptanalysis of Trivium and KATAN....Pages 200-212 Duplexing the Sponge: Single-Pass Authenticated Encryption and Other Applications....Pages 320-337 Blockcipher-Based Double-Length Hash Functions for Pseudorandom Oracles....Pages 338-355 Some Instant- and Practical-Time Related-Key Attacks on KTANTAN32/48/64....Pages 213-229 Analysis of the Initial and Modified Versions of the Candidate 3GPP Integrity Algorithm 128-EIA3....Pages 230-242 New Insights on Impossible Differential Cryptanalysis....Pages 243-259 Boomerang Distinguishers on MD4-Family: First Practical Results on Full 5-Pass HAVAL....Pages 1-18 Improved Analysis of ECHO -256....Pages 19-36 Provable Chosen-Target-Forced-Midfix Preimage Resistance....Pages 37-54 On CCA-Secure Somewhat Homomorphic Encryption....Pages 55-72 Efficient Schemes for Anonymous Yet Authorized and Bounded Use of Cloud Resources....Pages 73-91 A Unified Framework for Small Secret Exponent Attack on RSA....Pages 260-277 Group Law Computations on Jacobians of Hyperelliptic Curves....Pages 92-117 ASC-1: An Authenticated Encryption Stream Cipher....Pages 356-372 On Various Families of Twisted Jacobi Quartics....Pages 373-383 Improved Three-Way Split Formulas for Binary Polynomial Multiplication....Pages 384-398 Sublinear Scalar Multiplication on Hyperelliptic Koblitz Curves....Pages 399-411 Faster Hashing to ${\mathbb G}_2$ ....Pages 412-430 Back Matter....Pages -
