Based on mutually coupled vertical-cavity surface-emitting lasers (VCSELs) with optical feedback, a bidirectional dualchannel chaos security communication system are proposed and theoretically investigated. The results show that, through selecting suitable system parameters, high-quality isochronal synchronization can be obtained for the x-, y-LP mode as well as the total intensities, respectively; the synchronization performances for each LP mode and the total intensities preserve a certain extent tolerance to intrinsic mismatched parameters except they are sensitive to frequency detuning between the two VCSELs. Based on the chaos synchronization of the x- and y-LP modes, bidirectional dual-channel communication performances have been preliminarily examined under two encryption methods, namely chaos masking (CMS) and additive chaos modulation (ACM)..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
