“…When electro-magnetic (EM) emission data collected by EM probe is used, the attack is called SEMA (Simple electro-magnetic analysis). DPA [6] is usually used in the attack against symmetric ciphers such as DES [5] or AES [5] algorithms. In the DPA, the attacker requires a large number of power traces in contrast to SPA.…”

Cryptosystems are widely used for achieving data confidentiality and authenticated access control. Recent cryptographic algorithms such as AES or RSA are computationally safe in the sense that it is practically impossible to reveal key information from a pair of plain and cipher texts if a key of sufficient length is used. A malicious attacker aims to reveal a key by exploiting implementation flaws in cryptographic modules. Even if there are no flaws in the software, the attacker will try to extract a secret key stored in the security hardware. The side-channel attacks (SCAs) are low cost and powerful against cryptographic hardware. The attacker exploits side-channel information such as power or electro-magnetic emission traces on the cryptographic circuits. In this paper, we will introduce the principle of SCAs and the countermeasures against SCAs.

“…The fundamental benefit in use of ECC technique is by providing same protection level with a smaller key length compared to RSA, thus will reduces the processing overhead and the processing time [1,2]. The ECC technique basically is more complicated to illustrate than either Diffie-Hellman or RSA.…”

Elliptic Curve Cryptography (ECC) lately obtained a lot of care in cryptography science because it is more secure than the other cryptography methods and it is consider as one of the most significant cryptography technique. The ECC offers same security with smaller key comparing with the RSA (approximately 160 bits vs. 1024 bits), hence, this will decreases processor overhead, lowering power consumption, increase processing speed, enhance the storage efficiency, requires smaller certificates and it is good in bandwidth saving. The ECC uses high level mathematical operations. The ECC is an algebraic structure in finite fields and it is differ than other encryption algorithm because of the cipher text is a points in Cartesian coordinates. This paper proposed a new effective implementation method for symmetric encryption over ECC by use of secret shared key between two parties and this key change for every symbol in message. This technique provides authentication, confidentiality and non-repudiation.

These threats for the elimination of many encryption technique improved [2,[6][7][8][9]. Cryptography is the all of mathematical technical studies related to information security.…”

Abstract. In this paper a different cryptographic method is introduced by using Power series transform, codes of ASCII and science of steganography. Here,we produce a new algorithm for cryptology,we use Expanded Laplace transformation of the exponential function for encrypting the plain text and we use codes of ASCII for support to the confidentiality of the chipertext. After, Chipertext have embedded by steganographic method in another plaintext to hide the existence of chipertext. We show corresponding inverse of Power Series transform for decryption.
