摘要：
本文提出一种新的对称加密方案构造，称为 SEBQ，其基于拟群结构。我们利用链式概念（如操作模式），并提出一种具有内置特性的分组密码。我们证明 SEBQ 能够抵抗选择明文攻击（CPA），并通过应用非平衡 Feistel 变换[19]，使其获得针对选择密文攻击（CCA）的安全性。随后，我们通过运行 NIST 测试套件对所提方案的随机性进行评估，并通过雪崩效应分析考察初始向量、秘密密钥和明文对密文的影响。我们还将结果与现有的基于拟群的方案[11,46]进行比较。此外，我们以加密和解密过程所需运算次数为指标，分析了计算复杂度。
英文摘要：
In this paper, we propose a novel construction for a symmetric encryption scheme, referred as SEBQ which is based on the structure of quasigroup. We utilize concepts of chaining like mode of operation and present a block cipher with in-built properties. We prove that SEBQ shows resistance against chosen plaintext attack (CPA) and by applying unbalanced Feistel transformation [19], it achieves security against chosen ciphertext attacks (CCA). Subsequently, we conduct an assessment of the randomness of the proposed scheme by running the NIST test suite and we analyze the impact of the initial vector, secret key and plaintext on ciphertext through an avalanche effect analysis. We also compare the results with existing schemes based on quasigroups [11,46]. Moreover, we analyze the computational complexity in terms of number of operations needed for encryption and decryption process.
