Hybrid Encryption Algorithm for Data Transmission over public network

Information Technology

NATIONAL CONFERENCE ON TECHNOLOGICAL ADVANCEMENTS IN ENGINEERING

To improve the data transmission over the public network is very essential aspect. Cryptography provides some methods for securing the data. For that Encryption Algorithms are used to protect the confidentiality of data. Hybrid encryption is a method used for securing the data. Hybrid encryption is a process by which combines two or more algorithms together and provides more security than a single encryption can do. This provides safe mechanism for data transmission over the network. This mechanism includes confidentiality, integrity, authentication of identity, and non-repudiation. This mechanism also provides dual protection by taking the advantages of the algorithms used, so the data transmission in the network will be more secure. Here, some hybrid encryption mechanisms are discussed; that are based on combination of 3DES and RSA algorithms and combination of AES and ABE algorithms. Encryption speed of 3DES algorithm is faster than RSA algorithm distribute key safely and easily . RSA algorithm AES overcomes the disadvantages of 3DES. It is an effective method to resolve the problem of safe transmission in Internet.
