Abstract: A secured digital communication system, comprising: at least one secured network connected device, comprising at least one hardware processor connected to at least one digital communication network interface, and adapted for: in at least one of a plurality of iterations: appending an identified cryptographic key value to a first sequence of digital bytes to produce an extended sequence of digital bytes; computing a cryptographic signature value by applying a fixed length low computation complexity chunk-based hash function to the extended sequence of digital bytes; appending the cryptographic signature value to the first sequence of digital bytes to produce a signed sequence of digital bytes; and sending at least one message comprising the signed sequence of digital bytes to at least one other secured network connected device via the at least one digital communication network interface.

Abstract: A secure network system comprising: at least one secured network connected device, comprising at least one hardware processor connected to at least one digital communication network interface, and adapted for: in at least one iteration of a plurality of iterations: executing a binary code for computing a maliciousness score in response to an input message, where the binary code is received from a remote server via a network and encapsulates a classification model trained, using a plurality of historical messages collected by the remote server from a plurality of devices, to compute the maliciousness score in response to the input message; receiving a message via the at least one network interface; computing a message maliciousness score by providing the message to the binary code; and providing the message to a software object executed by the hardware processor to perform a message oriented task, subject to the message maliciousness score.

Abstract: A method comprising: identifying a gesture performed via a GUI, for navigating a set of user credentials from a list into respective regions within a priority scale having regions indicative of relative priority for attendance, sending to the user credentials, invitations including time slots and locations each associated with a relative ranking score, receiving responses, each associated with relative response ranking score and a participation score, and computing a single time slot and a single location by weighting the relative response ranking scores and participation scores for the time slots and locations, according to the region of the respective user credentials within the priority scale and according to the relative ranking score assigned to each time slot and each location, and presenting, within the priority scale of the GUI, color coding indicative of likelihood of attendance at the single time slot and the single location by each user credential.
