Weak Encryption: Insecure Mode of Operation
Abstract
請勿將密碼編譯加密演算法與不安全的作業模式搭配使用。
Explanation
區塊編碼器的作業模式是一種演算法,它描述如何一再套用密碼的單一區塊作業來安全地轉換超過一個區塊的資料量。有些作業模式包含了電子程式碼籍 (ECB)、加密區塊鏈結 (CBC)、加密回饋 (CFB) 和計數器 (CTR)。
在本質上,ECB 模式的安全性較低,因為它會為完全相同的純文字區塊產生一樣的加密文字。CBC 模式容易遭受 Padding oracle 攻擊。CTR 模式則無這些弱點,因此為優先選用的模式。
範例 1:以下程式碼使用 AES 加密搭配 ECB 模式:

Abstract
識別的呼叫使用無法保證敏感資料保密性的低等加密演算法。
Explanation
過時的加密演算法 (如 DES) 無法再提供可供敏感資料使用的足夠保護。加密演算法依賴金鑰長度做為其中一個能夠確保加密強度的主要機制。加密強度通常是依產生有效金鑰時所需的時間及運算能力來衡量。運算能力的進步,使現在能夠在合理的時間範圍內取得短型密鑰。例如,在 1970 年代初次開發出 DES 演算法時,要破解此演算法中使用的 56 位元金鑰面臨極大的運算困難,但今天可使用平常便可取得的設備,在不到一天內破解 DES。

Abstract
請勿將密碼編譯加密演算法與不安全的作業模式搭配使用。
Explanation
區塊編碼器的作業模式是一種演算法,它描述如何一再套用密碼的單一區塊作業來安全地轉換超過一個區塊的資料量。有些作業模式包含了電子程式碼籍 (ECB)、加密區塊鏈結 (CBC)、加密回饋 (CFB) 和計數器 (CTR)。
在本質上,ECB 模式的安全性較低,因為它會為完全相同的純文字區塊產生一樣的加密文字。CBC 模式容易遭受 Padding oracle 攻擊。CTR 模式則無這些弱點,因此為優先選用的模式。
範例 1:以下程式碼使用 AES 加密搭配 ECB 模式:

Abstract
請勿將密碼編譯加密演算法與不安全的作業模式搭配使用。
Explanation
區塊編碼器的作業模式是一種演算法,它描述如何一再套用密碼的單一區塊作業來安全地轉換超過一個區塊的資料量。有些作業模式包含了電子程式碼籍 (ECB)、加密區塊鏈結 (CBC)、加密回饋 (CFB) 和計數器 (CTR)。
在本質上,ECB 模式的安全性較低,因為它會為完全相同的純文字區塊產生一樣的加密文字。CBC 模式容易遭受 Padding oracle 攻擊。CTR 模式則無這些弱點,因此為優先選用的模式。
範例 1:以下程式碼使用 AES 加密搭配 ECB 模式:
