Method, apparatus, device and medium for processing genetic data

An electronic device comprises:

• at least one processing unit;
• and
• at least one memory coupled to the at least one processing unit and storing instructions executed by the at least one processing unit, the instructions, when executed by the at least one processing unit, causing the electronic device to perform a method for processing genetic data, comprising:
• receiving, in a normal execution environment in a data processing system, ciphertext of genetic data from a data providing system via a public channel between the normal execution environment and the data providing system;
• in a trusted execution environment in the data processing system,
• receiving, a key for decrypting the ciphertext of the genetic data, from the data providing system via a secure channel between the trusted execution environment and the data providing system;
• decrypting the ciphertext of the genetic data using the key to obtain plaintext of the genetic data;
• and
• processing the plaintext of the genetic data to determine a processing result of the genetic data.

A non-transitory computer-readable storage medium, storing a computer program thereon, the computer program, when executed by a processor, causing the processor to implement a method for processing genetic data, comprising:

• receiving, in a normal execution environment in a data processing system, ciphertext of genetic data from a data providing system via a public channel between the normal execution environment and the data providing system;
• in a trusted execution environment in the data processing system,
• receiving, a key for decrypting the ciphertext of the genetic data, from the data providing system via a secure channel between the trusted execution environment and the data providing system;
• decrypting the ciphertext of the genetic data using the key to obtain plaintext of the genetic data;
• and
• processing the plaintext of the genetic data to determine a processing result of the genetic data.
