In Indonesia, it has been a public knowledge that cigarette is dangerous to consume. However, the involvement of advertisement and its huge economic benefit has driven the government to freely let cigarette be widely promoted; nevertheless the image of the cigarette would not be shown on the screen as per agreement with advertisers. These series of complexities in the cigarette advertisements have attracted the authors to investigate the way cigarettes are promoted without explicitly exposing them. Cigarette, advertising language, pragmatics, Indonesia advertisement, Indonesia In Indonesia, advertisements have become a major agent to influence society recently.
The categories of Signature scheme, which are modification of the ElGamal Signature Scheme, were developed. It is highly imperative to be cautious regarding the security of a signature scheme, in which a signed message could perform a vital financial and legal transaction as opposed to a cryptosystem where a message might be encrypted and decrypted only once using any cryptosystem which is known to be secure at th e time the message is being encrypted.
Again, a signed message is very likely to be Corresponding Author: Also, the message x in DSA should be hashed using SHA-1 before it is signed with a bit signature over bit message digest.
There are two points P and Q on the elliptic curves, which are define over Zp for some given prime number p. In order to compute and verify a signature in this ECDSA, a secret number k is chosen randomly and the value of kA is computed.
Let p be a prime and E be an elliptic curve defined over Fp. Let A be a point on E having prime order q, such that the Discrete Logarithm problem in A is infeasible. The value p, q, E, A and B are the public key, and m is the private key.
Otherwise the signature should be rejected. Hence, the signature is accepted Therefore the signature 85, 84 on message should be accepted by Ade. However, the signature 97, 53 example of the schnnor signature example over a message 50 cannot be verified and therefore be rejected.
We wish to verify Corresponding Author: Also, k must not be used to sign two different message x. This section examines the goal of an adversary, attack models and the security provided by signature scheme.
Some possible attack models against digital signature are here under-listed: This attack occurs when adversary possesses a list of messages previously signed by his host, i. The signature scheme since its existence has became a veritable tool in securing the information on the Internet.
However, it is quite notable that an information security is a continuous exercise that is subjecting to empirical analysis.
Anybody can therefore; lay his hand on the implementation and compute the equivalents of various digital signature algorithms.
The programming implementation also displays the speed of each of the algorithm. Journal of Cryptology  Schnorr, C. He has published some papers in the above-mentioned research areas.
