Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a secure communication device like SME-PED is used to provide high-level security, then security is improved, but device complexity and cost increase, limiting feature updates and requiring users to carry multiple devices
Solution Approach 1:
The invention divides the secure communication system into two separate components: a cryptographic device that provides security functions and a communication device that provides communication capabilities. The cryptographic device can be disparately located from the communication device, allowing each component to be optimized independently. This segmentation resolves the contradiction by enabling high security without requiring the communication device itself to be complex.
Solution Approach 2:
The cryptographic device is designed to work with multiple different communication devices through network connections, providing universal security functionality across various platforms. This allows a single cryptographic device to secure multiple communication devices, reducing the need for users to carry multiple specialized devices while maintaining high security standards.
2Reliability
If encryption hardware is integrated into the communication device, then security is improved, but the device becomes larger and more expensive
Solution Approach 1:
The invention extracts the encryption hardware from the communication device and places it in a separate cryptographic device. This allows the communication device to remain compact and consumer-sized while still providing high-level security through the externally located cryptographic device that performs all encryption and decryption operations.
3Reliability
If discrete cryptographic device and communication device are used separately, then security and communication features are improved, but integration between them is limited
Solution Approach 1:
The invention introduces a network connection as an intermediary between the cryptographic device and the communication device. This allows the two disparately located devices to communicate effectively, with the network serving as a mediator that enables seamless integration while maintaining the physical separation needed for security. The network connection allows commands, data, and encrypted communications to flow between the devices.

AI summary
The present invention relates generally to facilitating secure voice and data communication by way of a commercially available communication device (i.e., smartphone/smartdevice). Specifically, the device and system for pairing a specialized cryptographic device with a non-specialized communication device, wherein the two devices engage in bidirectional communication to facilitate encryption of voice and data for secure transmission over a network. While providing the sensitive cryptographic features for secure communications, the cryptographic device further implements and enforces security policies for the communication device by way if an intermediary native application executed at the communication device. The encryption device is suitably designed to be carried discreetly and may be used in conjunction with a commercially available communication device.
