摘要： According to an embodiment, an authority changing device includes a first determiner, a second determiner, and a changing unit. A first authority is defined by a first combination of first to third item values, and a second authority is defined by a second combination of the fourth to sixth item values. The first determiner uses a logical expression to determine whether the change from the first authority to the second authority is possible, not possible, or unknown. The second determiner uses a first table to determine the availability of change from the first authority to the second authority when the availability of the change is determined to be unknown. The changing unit changes the first authority to the second authority when the change is determined to be possible.

摘要： An example information processing device includes first and second receiving units, a deciding unit, and first and second transmitting units. The first receiving unit receives adjustment limit information from a plurality of first external devices. The deciding unit determines adjustment rules on the basis of the adjustment limit information. The first transmitting unit transmits the adjustment rules to second and third external devices. The second receiving unit receives determination information from a fourth external device. The second transmitting unit transmits the adjustment rules to the first external devices when integrated schedule information satisfies a condition. When the integrated schedule information does not satisfy the condition, the deciding unit changes the adjustment rules. When the deciding unit has changed the adjustment rules, the first transmitting unit transmits new adjustment rules to the second and third external devices.

摘要： When converting an affine representation representing a 2r-th degree algebraic torus T2r(Fq) (r is a prime number, and q is an integer) to a projective representation representing a quadratic algebraic torus T2(Fq̂r), a representation converting apparatus acquires member (c0,c1, . . . ,cr−2), (ci is a member of a finite field Fq, where 0≦i≦r−2) of a 2r-th degree algebraic torus T2r(Fq) represented by the affine representation. The apparatus performs a multiplication operation on the acquired member. The multiplication operation is determined by a condition under which a member of a quadratic algebraic torus T2(Fq̂r) is included in the 2r-th degree algebraic torus T2r(Fq), a modulus and a base of a quadratic extension, and a modulus and a base of an r-th degree extension. The representation converting apparatus then performs an addition and subtraction operation determined by the condition, the moduli, and the bases.

摘要： In a computing device that calculates a square of an element in a finite field, a vector representation of the element in the finite field is accepted. The vector representation includes a plurality of elements. The computing device performs a multiplication operation on a base field using the accepted elements, and obtains a multiplication value. The multiplication operation is determined by a condition under which the element in the finite field is placed in an algebraic torus. The computing device performs an addition and subtraction operation using the obtained multiplication value and the accepted elements, and obtains a calculation result of the square of the element. The addition and subtraction operation is determined by the condition. The computing device then outputs the calculation result.

摘要： A decrypting apparatus that decrypts encrypted data that has been encrypted first data containing plain data, the encrypted data being represented by using an affine representation F_{p̂m}×F_{p̂m}̂*(where p: a prime number; m: a natural number; and ̂: exponentiation) obtains encrypted data represented in a vector format and a secret key corresponding to a public key and judges whether a vector component contained in the encrypted data is the affine representation F_{p̂m}×F_{p̂m}̂*. Further, based on the result of the judging process, the decrypting apparatus maps the vector component onto each of the members of an algebraic torus by forming a decompression map and decrypts the encrypted data mapped onto each of the members of the algebraic torus, by using the secret key, therefore obtains the plain data.

摘要： According to one embodiment, a representation converting unit converts a set of n elements (h0, h1, . . . , hn−1) (hi: a member of a finite field Fp^m, 0≦i≦n−1) that is a projective representation of a member g of an n-th degree algebraic torus Tn(Fp^m) (n: positive integer, p: prime number, m: positive integer) into a limited projected representation expressed by a set of n elements (h′0, h′1, . . . , h′n−1) (h′i: a member of the finite field Fp^m, 0≦i≦n−1) in which at least one element out of the n elements is a zero element 0 or an identity element 1. An arithmetic unit omits part of Fp^m operation that is arithmetic operation in the finite field Fp^m based on a fact that an element in the set of n elements (h′0, h′1, . . . , h′n−1) represented by the limited projective representation is a zero element “0” or an identity element “1” when performing Fp^mn operation that is arithmetic operation of a finite field Fp^mn in combination with the Fp^m operation.

摘要： A compressing unit compresses an element on an algebraic torus into affine representation according to a compression map. A determining unit determines whether a target element on the algebraic torus to be compressed is an exceptional point representing an element on the algebraic torus that cannot be compressed by the compression map.
