Definition ∞ Runtime encryption is a method of encrypting data while it is actively being processed or used by a computer program. This differs from traditional encryption, which typically secures data at rest or in transit. Runtime encryption ensures that sensitive information remains protected even when it is loaded into memory for computation. This technology is critical for applications requiring high levels of data confidentiality during active processing.
Context ∞ Runtime encryption is an emerging area of cryptographic research with significant implications for data security in sensitive applications, including those handling digital assets. Current discussions often focus on its application in secure computation and confidential computing environments, aiming to protect data from unauthorized access even by system administrators. Future advancements are expected to enhance performance and broaden the applicability of runtime encryption across various computational tasks.
