In the realm of technology, a revolutionary concept, often shrouded in obscurity, is poised to revolutionize our existence – Confidential Computing (CC).

Defined by the Confidential Computing Consortium, CC signifies safeguarding data in active operation by executing computations within a hardware-based Trusted Execution Environment.

These secluded domains thwart any unsanctioned access or alteration of applications and data during processing, thereby heightening security assurances for organizations handling sensitive and regulated data.

While the significance of encrypting data during transmission or storage is widely acknowledged today, preserving data integrity during its ‘in use’ state – a phase where it undergoes processing by a CPU (or in modern times, by a collection of GPUs, especially in AI applications) – remains a specialized venture, not comprehensively understood in the corporate world.

Yet, this final frontier of data protection stands as a pivotal factor enabling developers to construct adaptable and trustworthy applications. These applications possess the ability to handle confidential data with complete assurance, under demonstrable controls. 

Solving this ultimate data protection challenge promises to revolutionize the entire landscape of computing. From expansive cloud-based corporate applications to IoT devices in household settings, this transformation holds vast potential. 

When coupled with other recent innovations such as multi-party computation and blockchain technology, the possibilities for creating software systems with unequivocal trust are boundless. These innovations extend from streamlined currency tokens and intelligent contracts to spontaneous multi-party exchanges.

Traditionally, ensuring data confidentiality and security mandated stringent control over the ‘execution environment’. Corporations typically processed their data within their secure on-premise facilities or through reputable third-party vendors, steering clear of generalized cloud environments. 

However, this approach is plagued by significant issues. These include exorbitant expenses tied to operating and securing dedicated data centers, the escalating complexity of operating systems, continual discovery of new vulnerabilities, and the inherent security risk posed by ‘hypervisor’ software, a common component of virtualization technologies. 

Furthermore, there’s the ever-present risk of internal negligence or malicious intent, as highlighted in Verizon’s 2023 Data Breach Investigations Report, which revealed that nearly 20% of company data breaches were instigated by their own personnel.

Moreover, the urgency of data security concerns no longer pertains solely to large corporations; it resonates with every individual, permeating every home. This escalation in awareness is fueled by the proliferation of intelligent IoT devices, which increasingly process deeply personal data.

Recent explorations into ‘homomorphic computing’ have emerged as a potential solution to these challenges. In this approach, data remains encrypted throughout, eliminating the risk of leaks, barring the compromise of the cryptographic key. 

However, this method imposes stringent limitations on the processing capabilities while data remains encrypted. While determining the average value of a confidential dataset is feasible, executing a universal, data-dependent smart contract transcends the scope of this technique. 

Additionally, homomorphic encryption schemes impose substantial computational overheads, rendering them prohibitively expensive or unwieldy for most practical applications.
