SCP-Mediated Secure LCS Channels Without Performance Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional LCS communication security techniques are limited and degrade performance, failing to adequately secure communications between Logically Composed Systems (LCSs) across multi-tenant environments, particularly when distributed across multiple resource systems.
Innovation Solution
A System Control Processor (SCP) engine configures secure communication channels using first and second keys to facilitate secure communication between host processing systems, enabling secure transmission of communications between LCSs via a network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional LCS communication security techniques are used, then security is provided, but performance degrades
Solution Approach 1:
The system segments security functionality into a dedicated security processing unit that operates independently from the main LCS processing. This allows security operations to be performed in parallel without blocking or slowing down the primary computation paths, thus maintaining performance while providing security.
Solution Approach 2:
A security processing unit acts as an intermediary between LCSs, handling all security-related operations. This intermediary manages cryptographic operations, authentication, and secure channel establishment without requiring the main LCS processing systems to be involved, preventing security overhead from degrading LCS performance.
2Reliability
If security is implemented between LCSs across multiple resource systems, then security coverage is improved, but system complexity increases
Solution Approach 1:
The security processing unit is designed as a universal component that can serve multiple LCSs across different resource systems. It provides centralized security management, authentication, and encryption services that work across the entire multi-tenant environment, eliminating the need for separate security implementations in each LCS or resource system.
Solution Approach 2:
The security processing unit serves as a centralized intermediary that mediates all security operations between LCSs. It manages security policies, handles cryptographic operations, and establishes secure channels without requiring complex security logic to be distributed across multiple systems, thereby reducing overall system complexity while improving security coverage.
3Reliability
If secure communication channels are established between multiple LCSs, then security is enhanced, but communication overhead increases
Solution Approach 1:
Secure communication channels are established in advance between LCSs through the security processing unit. Authentication, key exchange, and channel setup are performed beforehand, so that when actual data communication occurs, the security mechanisms are already in place and do not add significant overhead to the communication process.
Solution Approach 2:
The security processing unit automates security operations including authentication, key management, and channel establishment without requiring manual intervention or complex coordination between LCSs. This self-service approach reduces communication overhead by eliminating repeated authentication handshakes and manual security configuration.

AI summary
A secure LCS communication system includes a first host processing system that is configured to provide a first LCS, a second host processing system that is configured to provide a second LCS, and an SCP device that is connected to the first host processing system and that is coupled to the second host processing system via a network. The SCP device uses first keys associated with the first LCS to configure a first secure communication channel with the first host processing system, and uses second keys associated with the first LCS and the second LCS to configure a second secure communication channel with the second host processing system via the network. When the SCP device receives a communication from the first LCS via the first secure communication channel that is directed to the second LCS, it transmits the communication via the second secure communication channel to the second LCS.
