| 发明名称 | Detection of data tampering of encrypted data | ||
| 摘要 | A device includes storage hardware to store a secret value and processing hardware coupled to the storage hardware. The processing hardware is to receive an encrypted data segment with a validator and derive a decryption key using the secret value and a plurality of entropy distribution operations. The processing hardware is further to verify, using the received validator, that the encrypted data segment has not been modified. The processing hardware is further to decrypt the encrypted data segment using the decryption key to produce a decrypted data segment responsive to verifying that the encrypted data segment has not been modified. | ||

| 主权项 | 1. A device comprising: storage hardware to store a secret value; and secure programmable logic device, coupled to the storage hardware, to: receive an encrypted data segment with a validator, wherein the encrypted data segment is part of a bitstream;derive a decryption key using the secret value and a plurality of entropy distribution operations;verify, using the received validator, that the encrypted data segment is unmodified;responsive to verifying that the encrypted data segment is unmodified, decrypt the encrypted data segment using the decryption key to produce a decrypted data segment; andcryptographically process the decryption key to derive an updated decryption key. | ||
