METHOD FOR PROTECTING DATA FROM ALGEBRAIC MANIPULATION

METHOD FOR PROTECTING DATA FROM ALGEBRAIC MANIPULATION

According to the present invention, a data protection method includes the following steps: receiving a data word (s ∈ f^d_q) to be protected; fixing a basis for a Riemann-Roch (L(m_dQ)) space to a F_q-vector space; evenly deducing index (i) from a set (I); and encoding s to (s,I,f_s(p_i)) ∈ f^d_q x...

Zusammenfassung:According to the present invention, a data protection method includes the following steps: receiving a data word (s ∈ f^d_q) to be protected; fixing a basis for a Riemann-Roch (L(m_dQ)) space to a F_q-vector space; evenly deducing index (i) from a set (I); and encoding s to (s,I,f_s(p_i)) ∈ f^d_q x I_n x F_q. 본 발명에 따른 데이터 보호 방법은, 보호될 데이터 워드()를 수신하는 단계; 리만-록(Riemann-Roch, L(mQ)) 공간에 대한 기저를-벡터 공간으로 고정하는 단계; 집합(I)으로부터 인덱스(i)를 균일하게 도출하는 단계; 및 s를로 인코딩하는 단계를 포함한다.
