An information processing apparatus inputs the first information and second information which is key information or a ciphertext of the functional encryption scheme that corresponds to a particular piece of second correspondence information into a decryption function of the functional encryption scheme and, when the truth value of a logical formula corresponding to the combination of the particular piece of first correspondence information corresponding to the first information and the particular piece of second correspondence information corresponding to the second information is true, generates a decryption result.

摘要： Security against CCA is improved without providing space for just improving the security against CCA in a ciphertext space. In encryption processing, a first ciphertext C1 is calculated from a plaintext M and a symmetric key K; a value containing a value corresponding to the symmetric key K and a value corresponding to the first ciphertext C1 is put into a collision-resistant function H to calculate a function value of the function H; and r corresponding to the function value is used to calculate second ciphertext C2=r·(Σμ=1nvμ·bμ)+ρ·bn+1∈G1n+1. In decryption processing, the second ciphertext C2∈G1n+1 and key information D1*=α·(Σμ=1nwμ·bμ*)+bn+1*∈G2n+1 are put into a bilinear function e to calculate a function value S˜=e(C2, D1*)∈GT; a value corresponding to the function value S˜ and the first ciphertext C1 are put into the collision-resistant function H to calculate a function value of the function H; and it is judged whether r˜ corresponding to the function value satisfies C2=r˜·(Σμ=1nvμ·bμ)+ρ˜·bn+1∈G1n+1.

摘要： A tag device causes a second calculator to read a confidential value from a confidential value memory and to apply a second function F2 which disturbs a relationship between elements of a definition domain and a mapping thereof to generate tag output information. The tag device delivers the tag output information to a backend apparatus. Subsequently, a first calculator reads out at least part of elements of the confidential value from the confidential value memory, and applies a first function F1, an inverse image of which is difficult to obtain, and a result of such calculation is used to update a confidential value in the confidential value memory by overwriting.
