    (a) In any communication between a State agency and the Comptroller in which a signature is required or used, any party to the communication may affix a signature by use of a digital signature that complies with the requirements of this Section. The use of a digital signature shall have the same force and effect as the use of a manual signature if and only if it embodies all of the following attributes:
        (1) It is unique to the person using it.
        (2) It is capable of verification.
        (3) It is under the sole control of the person using
    
it.
        (4) It is linked to data in such a manner that if the
    
data are changed, the digital signature is invalidated.
        (5) It conforms to regulations adopted by the
    
Comptroller.
    (b) The use or acceptance of a digital signature shall be at the option of the parties. Nothing in this Section shall require a State agency to use or permit the use of a digital signature.
    (c) "Digital signature" has the meaning ascribed to that term in the Electronic Commerce Security Act.
