To guarantee the secure transmission, we employ an independent randomization encoding strategy to encode the confidential message. We aim to maximize the network utility. Based on the finite length of a secrecy codewords strategy, we develop an improved control algorithm, subject to network stability and secrecy outage requirements. On the basis of the Lyapunov optimization method, we design an control algorithm, which is decomposed into end-to-end secrecy encoding, flow control and routing scheduling. The simulation results show that the proposed algorithm can achieve a utility result that is arbitrarily close to the optimal value. Finally, the performance of the proposed control policy is validated with various network conditions.<\/jats:p>","DOI":"10.3390\/a12020049","type":"journal-article","created":{"date-parts":[[2019,2,25]],"date-time":"2019-02-25T10:56:53Z","timestamp":1551092213000},"page":"49","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Secrecy Control of Wireless Networks with Finite Encoding Blocklength"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4700-0844","authenticated-orcid":false,"given":"Qiuming","family":"Liu","sequence":"first","affiliation":[{"name":"Nanchang of Jiangxi University of Science and Technology, 1180 Shuanggang Road, Nanchang 330013, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shumin","family":"Liu","sequence":"additional","affiliation":[{"name":"Nanchang of Jiangxi University of Science and Technology, 1180 Shuanggang Road, Nanchang 330013, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chunshui","family":"Zeng","sequence":"additional","affiliation":[{"name":"Nanchang of Jiangxi University of Science and Technology, 1180 Shuanggang Road, Nanchang 330013, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaohong","family":"Qiu","sequence":"additional","affiliation":[{"name":"Nanchang of Jiangxi University of Science and Technology, 1180 Shuanggang Road, Nanchang 330013, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"He","family":"Xiao","sequence":"additional","affiliation":[{"name":"Nanchang of Jiangxi University of Science and Technology, 1180 Shuanggang Road, Nanchang 330013, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,2,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1355","DOI":"10.1002\/j.1538-7305.1975.tb02040.x","article-title":"The wire-tap channel","volume":"54","author":"Wyner","year":"1975","journal-title":"Bell Syst.
