The contents of the present document are subject to continuing work within the TSG and may change following formal TSG approval. S
19、hould the TSG modify the contents of the present document, it will be re-released by the TSG with an identifying change of release date and an increase in version number as follows: Version x.y.z where: x the first digit: 1 presented to TSG for information; 2 presented to TSG for approval; 3 or grea
20、ter indicates TSG approved document under change control. y the second digit is incremented for all changes of substance, i.e. technical enhancements, corrections, updates, etc. z the third digit is incremented when editorial only changes have been incorporated in the document. Introduction This Rep
21、ort has been produced by ETSI SAGE Task Force for the design of the GSM A5/3 and GEA3 encryption algorithms. The work described in this report was undertaken in response to a request made by Security Group GSM Association. The work was done under supervision of the ETSI Mobile Competence Centre (MCC
22、) and the GSM Association. ETSI ETSI TR 155 919 V15.0.0 (2018-07)53GPP TR 55.919 version 15.0.0 Release 151 Scope This Technical Report has been prepared by the ETSI SAGE GSM A5/3 Task Force, and gives a detailed report on the design and evaluation of the A5/3 encryption algorithms for GSM and ECSD,
