1[3. Authentication of electronic records.--(1) Subject to the provisions of this section any subscribermay authenticate an electronic record by affixing his digital signature.

Explanation.--For the purposes of this sub-section, "hash function" means an algorithm mapping ortranslation of one sequence of bits into another, generally smaller, set known as --hash result" such that anelectronic record yields the same hash result every time the algorithm is executed with the same electronicrecord as its input making it computationally infeasible-- (a) to derive or reconstruct the original electronic record from the hash result produced by thealgorithm; (b) that two electronic records can produce the same hash result using the algorithm. (3) Any person by the use of a public key of the subscriber can verify the electronic record. (4) The private key and the public key are unique to the subscriber and constitute a functioning keypair.]

1[3A. Electronic signature.--(1) Notwithstanding anything contained in section 3, but subject to theprovisions of sub-section (2), a subscriber may authenticate any electronic record by such electronicsignature or electronic authentication technique which-- (a) is considered reliable; and (b) may be specified in the Second Schedule. (2) For the purposes of this section any electronic signature or electronic authentication techniqueshall be considered reliable if-- (a) the signature creation data or the authentication data are, within the context in which they areused, linked to the signatory or, as the case may be, the authenticator and to no other person; (b) the signature creation data or the authentication data were, at the time of signing, under thecontrol of the signatory or, as the case may be, the authenticator and of no other person; (c) any alteration to the electronic signature made after affixing such signature is detectable; (d) any alteration to the information made after its authentication by electronic signature isdetectable; and (e) it fulfils such other conditions which may be prescribed. (3) The Central Government may prescribe the procedure for the purpose of ascertaining whetherelectronic signature is that of the person by whom it is purported to have been affixed or authenticated. (4) The Central Government may, by notification in the Official Gazette, add to or omit anyelectronic signature or electronic authentication technique and the procedure for affixing such signaturefrom the Second Schedule: Provided that no electronic signature or authentication technique shall be specified in the SecondSchedule unless such signature or technique is reliable. (5) Every notification issued under sub-section (4) shall be laid before each House of Parliament.]
