Abstract: Systems and methods are disclosed, especially designed for very compact hardware implementations, to generate random number strings with a high level of entropy at maximum speed. For immediate deployment of software implementations, certain permutations have been introduced to maintain the same level of unpredictability which is more amenable to hi-level software programming, with a small time loss on hardware execution; typically when hardware devices communicate with software implementations. Particular attention has been paid to maintain maximum correlation immunity, and to maximize non-linearity of the output sequence. Good stream ciphers are based on random generators which have a large number of secured internal binary variables, which lead to the page synchronized stream ciphering. The method for parsed page synchronization which is presented is especially valuable for Internet applications, where occasionally frame sequences are often mixed. The large number of internal variables with fast diffusion of individual bits wherein the masked message is fed back into the machine variables is potentially ideal for message authentication procedures.

Abstract: A method for data cryptography includes accepting input data, which contains a section that is to undergo a cryptographic operation and starts at an offset with respect to a beginning of the input data, by a Direct Memory Access (DMA) module. The input data is aligned by the DMA module to cancel out the offset. The aligned input data is read out of the DMA module, and the cryptographic operation is performed on the section.

Abstract translation: 一种用于数据加密的方法包括：接受直接存储器访问（DMA）模块的输入数据，该输入数据包含要进行密码操作并且相对于输入数据的开始以偏移开始的部分。 输入数据由DMA模块对齐，以抵消偏移量。 从DMA模块中读取对齐的输入数据，并对该部分执行加密操作。

Abstract: A method for random number generation includes generating random number sequences using a Random Number Generator (RNG) circuit having an externally-modifiable configuration. The RNG circuit generates a first random number sequence having a first measure of randomness. The configuration of the RNG circuit is modified, causing the RNG circuit to generate a second random number sequence having a second measure of the randomness, indicating a degree of the randomness that is no less than the first measure.

Abstract translation: 用于随机数生成的方法包括使用具有外部可修改配置的随机数生成器（RNG）电路来生成随机数序列。 RNG电路产生具有第一随机度量的第一随机数序列。 RNG电路的配置被修改，导致RNG电路产生具有随机性的第二测量的第二随机数序列，指示不小于第一测量的随机程度。
