WebThe first direct construction of lattice based digital signatures in the standard model was given in (1). Technically, (1) constructs one-time signatures , i.e., signature schemes that can be securely used to sign only one message, and then extends them to sign arbitrarily many messages using a standard tree construction. WebNov 3, 2003 · More precisely, a valid signer can now create signatures that are a factor of N 1 4 closer to the expected closest vector in the lattice than was previously possible using the standard lattice of (8). paolo antonacci etàWebThe difference between NTRUEncrypt and NTRUSign is in how they use the lattice. All the NTRU algorithms are based on solving the Close Vector Problem in a particular form of lattice known as an "ideal lattice". For NTRUEncrypt, the encryption method is basically: Select a random point in the lattice. おいでやすこが m1 決勝ネタ
