,Malicious Hashing: Eve’s Variant of SHA-1, malicious purposes, such as the injection of user surveillance features. To encourage further research on such malicious hash functions, we propose definitions of malicious hash functions and of associated security notions.

OMD: A Compression Function Mode of Operation for Authenticated Encryption,Instantiations of OMD using the compression functions of SHA-256 and SHA-512, called OMD-SHA256 and OMD-SHA512, respectively, provide much higher quantitative level of security compared to the AES-based schemes. OMD-SHA256 can benefit from the new Intel SHA Extensions on next-generation processors.

,Side-Channel Analysis of Montgomery’s Representation Randomization,on’s correlation as distinguisher. In this paper however, we exhibit an important flaw in the countermeasure and we show, through various simulations, that it leads to efficient first-order correlation-based attacks.

Linear Biases in AEGIS Keystream,ising correlation between ciphertexts at rounds . and ., although the biases would require . data to be detected. Due to their data requirements, neither attack threatens the practical security of the cipher.

,Malicious Hashing: Eve’s Variant of SHA-1,ding executables, archives, and images. Our malicious SHA-1 instances have round constants that differ from the original ones in only 40 bits (on average). Modified versions of cryptographic standards are typically used on closed systems (e.g., in pay-TV, media and gaming platforms) and aim to diffe

Binary Elligator Squared,ty for anonymity and censorship circumvention applications): the “Elligator” technique due to Bernstein et al. (ACM CCS 2013), which is simple but supports a somewhat limited set of elliptic curves, and its variant “Elligator Squared” suggested by Tibouchi (FC 2014), which is slightly more complex b
