Claim:
1. A method for transmitting signed data, comprising: receiving, from an external device, a signing request data packet at an instruction execution system of an electronic signature token, the instruction execution system having at least one processor, wherein the signing request data packet comprises data to be signed; signing the data to be signed with the instruction execution system of the electronic signature token to obtain signed data; obtaining a preset first transmitting strategy, generating first data to be transmitted based on to a part of the signed data and according to the preset first transmitting strategy, and transmitting the first data to be transmitted to the external device according to the preset first transmitting strategy, the first data to be transmitted being transmitted all at once or divided into multiple segments of first data, each segment of first data being transmitted individually, with the instruction execution system of the electronic signature token; after receiving the signing request data packet, extracting critical information of the data to be signed with the instruction execution system of the electronic signature token, and outputting the critical information of the data to be signed, with a display or sound device of the electronic signature token; receiving a confirmation instruction for the outputted critical information of the data to be signed with an interface or a key of the electronic signature token; and after receiving the confirmation instruction, obtaining a preset second transmitting strategy, generating second data to be transmitted based on a remaining part of the signed data and according to the preset second transmitting strategy, and transmitting the second data to be transmitted to the external device according to the preset second transmitting strategy, the second data to be transmitted being transmitted all at once or divided into multiple segments of second data, each segment of second data being transmitted individually, with the instruction execution system of the electronic signature token.
