Applications Of The RSA, Encryption, Asymmetric Algorithm

Abstract RSA is a widely used asymmetric algorithm. It is commonly used as a public key cryptography solution for many applications including TLS and e-commerce. However, not only is the algorithm 40 years old, there have been numerous breaches of the algorithm. There also exist more secure alternatives, such as elliptic curve cryptography. It is time to replace the aging RSA. Keywords: RSA, encryption, asymmetric cryptography Introduction RSA is a widely used public key/asymmetric algorithm (Ambedkar, Gupta, Gautam, Bedi, 2011; Mao, 2011; Stallings, 2010; Yeh, Huang, Lin, Chang, 2009). It is used extensively in e-commerce solutions, as well as in most digital certificates (Ahmed, 2010; Aà ¯meur, Brassard, †¦show more content†¦In their methodology, Heninger and Shacham (2009) formulated a series of linear equations that would progressively approximate the RSA private key. This technique is very similar to the linear cryptanalysis method utilized for cryptanalysis of symmetric key algorithms (Alekseychuck, Kovalchuk, Palchenko, 2007; Keliher, 2007; Swenson, 2008). Zhao and Qi (2007) used a similar methodology to derive RSA private keys, also attacking smaller modulus implementations. Aciicmez and Schindler (2008) examined the RSA algorithm, specifically as implemented in SSL. SSL, or Secure Sockets Layer, is the protocol used to provide encryption on websites (Mao, 2011; Stallings, 2010; Stanoyavich, 2010). While the actual protocol has since been supplanted by a newer protocol, TLS (Transport Layer Security), many sources still use the term SSL (Stallings, 2010). In their study of SSL using RSA, Aciicmez and Schindler (2008) examined the timing for modular arithmetic operations used in that specific implementation of RSA. This ultimately led to a method for factoring the public key, thus yielding the private key used in that RSA implementation. The authors of this study were able to significantly decrease the time required to factor the public key in order to derive the private key (Aciicmez Schindler, 2008). Kleinjung et al. (2010), took a more traditional approach in their attempt to break RSA. The method most often employed to attempt to derive theShow MoreRelatedData Security Cloud Computing Using Rsa Algorithm1321 Words   |  6 PagesData Security in Cloud Computing using RSA Algorithm Abstract: In cloud computing, data security is the major issue. Security in single cloud is less popular than in multicloud due to its ability to reduce security risks. In this paper, we describe a new architecture for security of data storage in multicloud. We use two mechanisms-data encryption and file splitting. When user upload a file ,it is encrypted using AES encryption algorithm. Then that encrypted file is divided into equal parts accordingRead MoreUse Of Encryption And Decryption Techniques Essay1609 Words   |  7 Pagesdays coming, the algorithms still not strong as cryptanalyst can recognize with them.
