TL;DR: In this paper, the O'Nan Scott classification of primitive groups was applied to prove that the permutation group generated by the round functions of an AES-like cipher is the alternating group.
Abstract: In a previous paper, we had proved that the permutation group generated by the round functions of an AES-like cipher is primitive. Here we apply the O'Nan Scott classification of primitive groups to prove that this group is the alternating group.

TL;DR: In this paper, a plurality of irreducible polynomials are used in self-synchronizing encryption/decoding circuits to eliminate the effects of missing data and enable encryption and decoding with communication lines on which gaps readily occur in the data being communicated.
Abstract: Self-synchronizing encryption/decoding circuits are provided with a plurality of irreducible polynomials. An irreducible polynomial to be used in encryption between sending and receiving stations is selected prior to cipher communication. On the sending side, the selected irreducible polynomial is used to encrypt communication information to be transmitted. On the receiving side, the selected irreducible polynomial is used to decrypt communication information that is received. Use of an irreducible polynomial as a key provides a simple structure which eliminates the effects of missing data and enables encryption and decoding with communication lines on which gaps readily occur in the data being communicated.

TL;DR: A chaotic system and two Nonlinear Feadback Shift Registers (NFSRs) are used to generate a new stream cipher that has good cryptographic characteristics and can be used for efficient encryption in resource-constrained devices or environments.
Abstract: A chaotic system and two Nonlinear Feadback Shift Registers (NFSRs) are used to generate a new stream cipher in this paper. This design can be used for efficient encryption in resource-constrained devices or environments. The chaotic system is quantified and integrated with two NFSRs based on the technology of Field Programmable Gate Array (FPGA). Many analyses are made from the angle of entropy in order to verify the cryptographic characteristics of the stream cipher, and National Institute of Standards and Technology (NIST) statistical test is completed to analyze the cipher. The test results show that the stream cipher here has good cryptographic characteristics.

TL;DR: Wang et al. as mentioned in this paper investigated the essential properties of MPPS and DNA coding, and then proposed an efficient chosen-plaintext attack to disclose its equivalent secret-key, which only needs ⌈ log 256 ( 3 ⋅ M ⋆ N ) ⌉ + 4 pair of chosen plain-images and the corresponding cipher-images, where M × N and “3” are the size of the RGB color image and the number of color channels, respectively.

TL;DR: The results from entropy analysis, difference analysis, statistical analysis, sequence randomness analysis, cipher sensitivity analysis depending on key and plaintext have proven that the compound chaotic sequence cipher can resist cryptanalytic, statistical and brute-force attacks, and especially it accelerates encryption speed, and achieves higher level of security.
