The invention relates to the technical field of communication data security, in particular to an electric power data private communication method based on a hybrid encryption algorithm. The method comprises the following steps that a sender randomly generates an AES session key and encrypts an electric power data plaintext m to be transmitted by using the session key to obtain a ciphertext M; thesender encrypts by adopting an elliptical encryption algorithm session key to obtain an encrypted key, and uses a digital signature; the ciphertext M, the encrypted key and the digital signature are sent to a receiver; the receiver decrypts the session key by using an ECC decryption algorithm and performs signature verification; if the signature verification is passed, the ciphertext M is decrypted by using the session key to obtain original power data m; if the signature does not pass, the error information is returned. Through hybrid encryption, the confidentiality and integrity of the dataare ensured, the encryption and decryption speeds are increased, meanwhile, the problems of key management and distribution of an AES encryption algorithm are solved, and the power data communicationprocess is optimized.
