The invention belongs to the technical field of biomedicine, and particularly relates to CRISPR-Cas9 (clustered regularly interspaced short palindromic repeats-Cas9) homing sequences and primers thereof, and a transgenic expression vector and an establishment method thereof. The CRISPR-Cas9 homing sequence sgRNA comprises SIDT1-gene-specific Target site-1 of which the target is positioned on E1 exon, and SIDT1-gene-specific Target site-2 of which the target is positioned on E2 exon, wherein the nucleotide sequence of the Target site-1 is disclosed as SEQ ID NO.8, and the nucleotide sequence of the Target site-2 is disclosed as SEQ ID NO.9. The CRISPR-Cas9 transgenic expression vector is formed by connecting the Cas9 homing sequence Target site-1 and Target site-2 to the BsmB I and Bbs I enzyme digestion sites of a recombinant shuttle Cas9 tool plasmid. The recombinant shuttle Cas9 tool plasmid can be quickly assembled with homing sequences of the two target sites of the genome, thereby packaging the recombinant adenovirus vector specifically for the two target sites; and the recombinant shuttle Cas9 tool plasmid can independently complete the editing of the large-segment genome without dependence on the synergistic actions. The establishment process is simple and quick, and has high efficiency for performing the genome large-segment editing function.

A new computational machine is invented, called a clock machine, that is a novel alternative to computing machines (digital computers) based on logic gates. In an embodiment, computation is performed with one or more clock machines that use time. In an embodiment, a cryptographic cipher is implemented with random clock machines, constructed from a non-deterministic process, wherein the compiled set of instructions (i.e., the implementation of the cryptographic procedure) is distinct on each device or chip that executes the cryptographic cipher. In an embodiment, by using a different set of clock machines to execute two different instances of the same cryptographic procedure, each execution of a procedure looks different to malware that may try to infect and subvert the cryptographic procedure. This cryptographic process also makes timing attacks more challenging. In an embodiment, a detailed implementation of the Midori cipher with random clock machines is described.
