Thin Client Protocol Translation for Secure Channel Encryption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable devices using older communication protocols, such as EMV 1.0, lack the security enhancements of newer protocols like EMV 2.0, making secure data exchanges between portable devices and remote computers challenging, especially when replacing a large number of devices is not feasible.
Innovation Solution
A thin client is used to receive transaction data from a portable device of an older type, determine its type, apply an encryption protocol associated with a newer type, and establish a secure channel with a remote computer to encrypt and decrypt data, enabling secure transactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If portable devices of the first type using older protocols continue to be used, then device replacement costs and complexity are avoided, but security levels remain insufficient compared to newer protocols
Solution Approach 1:
The patent introduces a thin client as an intermediary device between the portable device and the remote computer. This thin client acts as a mediator that receives data from the portable device using the older first protocol, applies encryption using the second protocol, and transmits the encrypted data to the remote computer. This intermediary approach allows secure communication without requiring replacement of the existing portable devices, thus improving security while maintaining protocol compatibility.
2Reliability
If all portable devices of the first type are replaced with second type devices, then security is improved, but the scale and cost of replacement become prohibitive
Solution Approach 1:
Instead of replacing billions of portable devices, the patent deploys thin clients at the communication endpoint (remote computer side). This intermediary approach secures communication from the point where data enters the network, protecting against eavesdropping and interception without requiring changes to the portable devices themselves. The solution scales by adding security infrastructure at the server end rather than requiring mass device replacement.
Solution Approach 2:
The patent changes the security parameters at the communication channel level rather than at the device level. By applying encryption protocols and establishing secure channels between the thin client and remote computer, the system transforms the security characteristics of the communication path. This allows existing portable devices to continue operating while the security parameters of the transmission channel are enhanced.
3Reliability
If encryption protocols are applied to data from older portable devices, then data security is improved, but processing complexity increases
Solution Approach 1:
The thin client serves as a dedicated intermediary that handles the complexity of protocol translation and encryption. By concentrating the encryption and decryption operations in this intermediary layer, the patent isolates the processing complexity from both the portable devices and the remote computer. The thin client manages the cryptographic operations, key management, and protocol conversion, simplifying the overall system architecture while maintaining high security standards.
Data Source
AI summary
A method for conducting a transaction is disclosed. A processor in a thin client may receive transaction data from a portable device of a first portable device type. The processor may determine that the portable device is the first portable device type. The processor may apply an encryption protocol associated with a second portable device type to the transaction data to create encrypted data. The processor may transmit the encrypted data to a remote computer, wherein the remote computer utilizes the encryption protocol to decrypt the transaction data, and thereafter process the transaction data to conduct the transaction.
