We analyze the security of elastic block ciphers against key-recovery attacks. An elastic version of a fixed-length block cipher is a variable-length block cipher that supports an...
At Crypto ’06, Bellare presented new security proofs for HMAC and NMAC, under the assumption that the underlying compression function is a pseudo-random function family. Converse...
NTRU is a fast public key cryptosystem presented in 1996 by Hoffstein, Pipher and Silverman of Brown University. It operates in the ring of polynomials Z[X]/(XN − 1), where the ...
NTRU is an efficient public-key cryptosystem proposed by Hoffstein, Pipher, and Silverman. Assuming access to a decryption oracle, we show ways to recover the private key of NTRU ...
