E-Voting with Hybrid Encryption RSA Algorithm

The previous encryption methods of hospital financial data have the problem of overburden. Therefore, a research study on hybrid encryption of hospital financial data based on Noekeon algorithm is proposed. From the basic principles of the Noekeon algorithm and the application and implementation of the Noekeon algorithm, a hybrid encryption scheme for hospital financial data based on the Noekeon algorithm is designed. In order to improve the security of the encryption system, the RSA algorithm is used to encrypt the encrypted content twice. The hybrid algorithm realizes the hybrid encryption of the hospital's financial data. Finally, a hybrid encryption system for hospital financial data based on Noekeon algorithm is designed. Experimental results show that this method has a higher success rate and better comprehensive performance. It not only improves the encryption efficiency of hospital financial data but also enhances the security of hospital financial data, which has greater application value.

Server System

Encryption is a well known technology for protecting sensitive data. ElGamal encryption and RSA algorithm is made before storing mails to mail server. ElGamal decryption and RSA decryption is made after retrieving mails from mail server. This system is implemented to secure mail server system for local government’s important mail messages. These algorithms consume a considerable amount of time and resources such as memory, CPU time, and computation time to encrypt and decrypt data. In this paper, the results are comparison of these algorithms in term of encryption time, decryption time, and memory usage over variable file sizes. After processing, it is proven that RSA performs a faster encryption process than ElGamal. However, ElGamal decryption process is faster than RSA. This system is also expressed comparison of storage Size between RSA and ElGamal. Both of these algorithms are cryptographic public-key algorithms but have functions in different ways. This system is using C# programming language and SQL Server to store mail messages.

Rsa Cryptography

This paper addresses the modification of RSA cryptography namely Symmetric-RSA, which seem to be equally useful for different cryptographic applications such as encryption, digital signature, etc. In order to design Symmetric-RSA, two prime numbers are negotiated using Diffie-Hellman key exchange protocol followed by RSA algorithm. As the new scheme uses Diffie-Hellman and RSA algorithm, the security of the overall system depends on discrete logarithm as well as factorization problem and thus, its security is more than public-key RSA. Finally, some new cryptographic applications of the proposed modifications are described that certainly extend the applications of the existing RSA.

The Impact

The Corona pandemic has created a push towards digitization in a number of fields, not least in the public sector including democratic processes. This of course includes an increased interest in e-voting via the Internet. The Council of Europe has a long-standing history of work in the field including two Recommendations – (2004)11 and (2017)5 – which have become the de facto yardstick against which every e-voting system is measured. Rec(2017)5 builds on a decade of experience with e-voting and particularly strengthens two concepts important in any electronic voting system: Voting secrecy and auditability/verifiability. This has distinct implications for the design of e-voting protocols. The aim of this paper is to analyse the impact on what arguably are the most popular voting protocol families, envelope and token protocols. How does the modified Recommendation impact on the viability of protocols and protocol design? The paper first presents the Council of Europe Recommendation and the technical issues it addresses. Then a model is introduced to assess a voting protocol against the Recommendation; a typical envelope and a token protocol are assessed in view of the model and finally the two assessments are compared including policy recommendations for a path to e-voting implementation.
