摘要:
A key generating apparatus generates a fibration X(x, y, t)=0 of an algebraic surface X serving as a part of a public key and defined on a finite field Fq (where q=pr [p is a prime number and r is an extended degree]) and a private key which is two sections D1 and D2 corresponding to the fibration X(x, y, t)=0. The fibration X(x, y, t) is generated such that a term (cij(t)xiyj) of xiyj having a 1-variable polynomial cij(t) of t as a coefficient is included in the fibration X(x, y, t).

摘要:
In a picture data reproducing method of reproducing picture data recorded to a recording medium according the MPEG standard, there is provisionally stored, into a stream buffer, picture data grouped as a GOP which begins with an I picture, the picture data provisionally stored in the stream buffer is read sequentially starting with a previous picture and the read picture data is decoded in the course of a FORWARD reproduction being done, and picture data acquired from the recording medium is additionally supplied to the stream buffer. When the picture data provisionally stored in the stream buffer have been read in the decoding step to before last N frames, a predetermined amount of picture data is additionally supplied, in the data adding step, beginning at the head of a GOP including picture data in the remaining N-th frame in the stream buffer. Thus, a smooth variable-speed reproduction can be done according to the MPEG Standard.

In an STC generating step, STCs (STC_d) delayed a time “System_delay” from STC (STC_medium) in compressed picture data read from a recording medium in the normal-speed reproduction mode is sequentially generated. In this STC generating step, there is set at shift from a variable-speed reproduction to normal-speed reproduction an STC initial value on the basis of results of comparison between PTS (PTS_s) in display picture data at the time of reproduction mode shift and {STC_medium at the shift−(delay due to the shift (shift_delay)+System_delay)}. Thus, when shifting the reproduction mode from a variable-speed one to normal-sped one in compliance with the MPEG standard, pictures can smoothly be displayed in the normal-speed reproduction mode without skipping over any displayed pictures.

摘要:
According to one aspect of the present invention, a public-key encryption method which can assure security even though a quantum computer appears, which can be securely realized by an existing computer, and which may be realized in a low-electric-power environment can be constituted. More specifically, one spect of the present invention uses an integer solution of a diophantine equation as a private key. In this manner, an encryption apparatus, a decryption apparatus, or a key generation apparatus of a public-key encryption method using a problem that calculates an integer solution of a diophantine equation having no general solution algorithm as the basis of security is realized. Therefore the above problem can be solved.
