Title: Decoding method, decoding device, and recording medium for decoding program
Inventor: KASAHARA MASAO
IPC: G09C1/00
Filed: 2000-03-10
Abstract: PROBLEM TO BE SOLVED: To provide a touch cryptographic system using polynominals with multi-variables. SOLUTION: M(α)=Mβ1(α).Mβ2(α).....Mβt(α) is obtained by regarding a message M as elements (m1, M2,..., mk) of a Galois field GF(2k), and multiplying M by the polynominals β1(α)-βt(α). A (n-k)th order noise vector r(α) is added to M(α) in series to expand it to nth order, and M(α) is converted into Γ by permutation operation. Γ is multiplied by the element γx (γ is a primitive root of a multiplicative group of a Galois field GF(2n), to make it into a cryptograph C(M). Practically, the cryptograph C(M) can be obtained by substituting the message M for X of the public key C(X).  The cryptograph C(M) is decoded into M by multiplying the cryptograph C(M) by γ-x to separate the noise vector r(α) through an inverse permutation operation, multiplying it by inverse elements of β1(α)-βt(α) and raising it to a suitable power.

Title: Device and method for processing waveform data
Inventor: KAKISHITA MASAHIRO
IPC: G10H7/02
Filed: 2000-03-14
Abstract: PROBLEM TO BE SOLVED: To avoid pitch variation when reading independent plural waveform data at the same rate. SOLUTION: Waveform memory is storing attack waveform data and loop waveform data read out successively. A pitch AP at the time of reproducing the attack waveform is calculated by the processing of steps 206-222. A pitch LWP at the time of reproducing the attack waveform data is calculated by the processing of steps 224-228. The attack waveform data are re-sampled according to the ratios of AR to LWP AP/LWP by the processing of steps 230-236, and are rewritten to attack waveform data re-sampled from the original attack waveform data. Thus, pitch variation can be avoided even if the attack waveform data and the loop waveform data are continuously read out at the same rate.
