Abstract: The invention includes methods and systems for establishing communication between a first device and a second device. The first device forming a data packet and appending the data packet with a unique secure hash of the second device's public key. Next, the first device authenticating with a server. Next, the first device sending the appended data packet with the unique secure hash of the second device's public key to the server with the server storing it in memory. Next, the second device connecting and identifying itself to the server. Next, the second device authenticating with the server. Next, having positively confirmed the second device's identity, the server delivering all data packets with the unique secure hash of the second device's public key to the second device. Finally, the second device decrypting the data packets using the second device's private key.

Abstract: A secured computing system comprising a secure computing device capable of securing a host-computing device positioned nearby. The system further comprises a processing device, a battery charging circuit and a power measurement device, secured peripherals, radios such as 3G, 4G, Wi-Fi, Wi-Max, and LTE, a processing device to perform the required instructions and algorithms for configuring and performing security functions, processing device support components such as memory and co-processors to support the processing device. Finally, the system includes embedded software such as the source or executable files necessary to perform the instructions or algorithms to perform security functions.

Abstract: A method for establishing communication via a VoIP network bypasses the IP PBX component conventionally used to obtain address information. Instead of obtaining the IP address from a location register of the IP PBX, the method involves use of a server configured to assign and provide to the caller's communication device a unique address (IP address/port) of a proxy. The caller then sends a Short Message Service (SMS) text message to the callee with the assigned address of the proxy. Thereafter, the caller and the callee connect at the assigned address of the proxy, thereby forming a communication path. Preferably, the devices operated by the parties are conventional smart phones. According to the preferred embodiment of the present invention, the method further comprises the steps of: determining whether to encrypt the communication; and encrypting the communication, if it is determined that the communication is to be encrypted.

Abstract: A comprehensive solution for providing secure mobile communication is provided. The system includes techniques for authentication and control of communication end-points; chain of trust to ensure devices are certified as authentic; contact list management; peer-to-peer encrypted voice, email, and texting communication; and a technique for bypassing an IP PBX to ensure high levels of security. The system is able to support use of commodity mobile communication devices (e.g., smart phones, laptops) over public carrier networks.
