摘    要:针对Rabin-OAEP算法在自适应选择密文攻击下是否安全,采用Adversary和Simulator进行的合理交互,论证“分解大整数N=pq是困难的(其中P,q为2个大素数),则Rabin-OAEP算法在自适应选择密文攻击下是安全的”的逆否命题,结果证明了Rabin—OAEP算法的安全性。

关 键 词:公钥密码  Rabin—OAEP算法  自适应选择密文攻击

Abstract:This paper discuses about the security against adaptive chosen-ciphertext attack aiming at Rabin-OAEP algorithm.Construction of reasonable interaction between Adversary and Simulator is used to provide the inverse proposition of "Decomposition of large integer N=pq is difficult(for p,q are two large prime numbers),the Rabin-OAEP is secure against adaptive algorithm chosen-ciphertext attack." Result proves claim that Rabin-OAEP is an security algorithm.
Keywords:public-key cryptography  Rabin-OAEP algorithm  adaptive chosen-ciphertext attack
