    Abstract: This application is applicable to the field of terminal technologies, and in particular, relates to a photographing method, an electronic device, and a computer-readable storage medium. The electronic device includes a camera lens. The method includes: A camera application of the electronic device sends a photographing command to a hardware abstraction layer of the electronic device in response to a photographing operation. The hardware abstraction layer determines, based on a first image, a to-be-photographed image in response to the photographing command. The first image is an image that is captured by the camera lens and that is obtained by the hardware abstraction layer after the camera application is started. To be specific, when the camera application detects the photographing operation, the camera application does not detect a current focusing status, and does not wait for the HAL to report a focusing completion state.

    Abstract: A proxy-based encryption method includes generating, according to a private key of a sending end and a public key of a receiving end, proxy keys that correspond to at least two proxy servers, respectively. The number of the proxy keys is equal to the number of the proxy servers. The method further includes sending encrypted ciphertexts and the proxy keys that correspond to the at least two proxy servers respectively to the at least two proxy servers, respectively, so that the at least two proxy servers re-encrypt the encrypted ciphertexts according to the corresponding proxy keys.

    Abstract: Embodiments of the present invention disclose a ciphertext processing method, apparatus, and system. The method includes: selecting a random secret value; calculating a private key according to a partial private key acquired by the local end and the random secret value; calculating a proxy key according to the private key of the local end and a public key publicized by an opposite end, where the public key is calculated by the opposite end according to a random secret value selected by itself and a system public parameter; and sending the proxy key, so that the opposite end acquires a ciphertext obtained after a re-encryption operation is performed, according to the proxy key, on a ciphertext sent by the local end, and performs decryption. Therefore, information security is ensured better and the Public Key Infrastructure (PKI) is avoided, thereby having better extensibility.
