DIGITAL SIGNATURE
Authentication of Electronic Records
Subject
to the provisions of this section any subscriber may
authenticate an electronic record by affixing his
digital signature.
The
authentication of the electronic record shall be
effected by the use of asymmetric crypto system and
hash function which envelop and transform the
initial electronic record into another electronic
record.
Explanation -
For
the purposes of this sub-section, "Hash function"
means an algorithm mapping or translation of one
sequence of bits into another, generally smaller,
set known as "Hash Result" such that an electronic
record yields the same hash result every time the
algorithm is executed with the same electronic
record as its input making it computationally
infeasible
|
(a) |
to
derive or reconstruct the original electronic
record from the hash result produced by the
algorithm; |
|
(b) |
that
two electronic records can produce the same hash
result using the algorithm. |
Any
person by the use of a public key of the subscriber
can verify the electronic record.
The
private key and the public key are unique to the
subscriber and constitute a functioning key pair. |
