A computer-implemented method of resource encryption and display, comprising: performing (S200) file splitting and local encryption on a pre-downloaded splash screen resource file, wherein the local encryption is encrypting of at least one component part of the pre-downloaded splash screen resource file obtained by performing the file splitting on the pre-downloaded splash screen resource file; calculating (S202) a current true time according to a correct time obtained from a server and a device power-on time difference of a client, and determining whether a current device time is reliable according to the true time, comprising: determining (S2020) whether the device has restarted since the correct time was last obtained from the server; when the device has not restarted, calculating (S2022) the current true time according to the correct time last obtained from the server and the device power-on time difference, wherein the device power-on time difference is a difference between a first power-on time of the device when the correct time was last obtained from the server and a second power-on time of the device that is obtained currently; comparing (S2024) whether a current system time is equal to the true time; and determining (S2026) that the current device time is reliable when the system time is equal to the true time; and when the current device time is reliable, obtaining (S204) the splash screen resource file through decryption and splicing, and displaying the splash screen resource file without waiting for communication with the server. performing (S200) file splitting and local encryption on a pre-downloaded splash screen resource file, wherein the local encryption is encrypting of at least one component part of the pre-downloaded splash screen resource file obtained by performing the file splitting on the pre-downloaded splash screen resource file; calculating (S202) a current true time according to a correct time obtained from a server and a device power-on time difference of a client, and determining whether a current device time is reliable according to the true time, comprising: determining (S2020) whether the device has restarted since the correct time was last obtained from the server; when the device has not restarted, calculating (S2022) the current true time according to the correct time last obtained from the server and the device power-on time difference, wherein the device power-on time difference is a difference between a first power-on time of the device when the correct time was last obtained from the server and a second power-on time of the device that is obtained currently; comparing (S2024) whether a current system time is equal to the true time; and determining (S2026) that the current device time is reliable when the system time is equal to the true time; and determining (S2020) whether the device has restarted since the correct time was last obtained from the server; when the device has not restarted, calculating (S2022) the current true time according to the correct time last obtained from the server and the device power-on time difference, wherein the device power-on time difference is a difference between a first power-on time of the device when the correct time was last obtained from the server and a second power-on time of the device that is obtained currently; comparing (S2024) whether a current system time is equal to the true time; and determining (S2026) that the current device time is reliable when the system time is equal to the true time; and when the current device time is reliable, obtaining (S204) the splash screen resource file through decryption and splicing, and displaying the splash screen resource file without waiting for communication with the server. <EOS>
