A secure reading and writing apparatus (1) receives a read command or a write command as input, and, when the read command is input, outputs a secret text [a[x]] which is an x-th element of a secret text sequence [a], and, when the write command is input, adds the secret text [a[x]] which is the x-th element of the secret text sequence [a], to a secret text [d]. A secure reading part (12) reads the secret text [a[x]] which is the x-th element from the secret text sequence [a]. A buffer addition part (13) adds a secret text [c] of an unreflected value c to the secret text [a[x]]. A buffer appending part (14) appends a secret text [x] and the secret text [d] to a write buffer [b]. When the number of elements of the write buffer [b] exceeds a predetermined value, a secure writing part (15) adds a value indicated with a secret text vector [b1] to an access position of the secret text sequence [a] which is indicated with a secret text vector [b0]."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Secure reading and writing apparatus, secure reading and writing method, and program","description":"Data is efficiently read from and written in a sequence without an access position being revealed.
