國際資料加密演算法

IDEA
An encryption round of IDEA
概述
设计者來學嘉和James Massey
衍生自PES
继承算法MMB, MESH, Akelarre,
IDEA NXT (FOX)
密码细节
密钥长度128 bits
分组长度64 bits
结构Lai-Massey scheme
重复回数8.5
最佳公开破解
The key can be recovered with a computational complexity of 2126.1 using narrow bicliques. This attack is computationally faster than a full brute force attack, though not, as of 2013, computationally feasible.[1]

國際資料加密演算法(英語:International Data Encryption Algorithm,縮寫為 IDEA),最早稱為改良建議加密標準Improved Proposed Encryption Standard,IPES),是密碼學上一種對稱密鑰分組密碼,由James Massey與來學嘉設計,在1991年首次提出。這個演算法的提出,是為了取代舊有的資料加密標準(DES)。[2]現在IDEA被認為是不安全的加密演算法。
