Professor, Institute ofInformation Technology & Management, New DelhiAbstractInformation security is the keyissue of today. Most of the information is being converted into the digitalform so that it can be stored and access easily, efficiently and securely. “Digitalform of Information” or “Digital form of Data” provides so many advantages likeflexibility, availability, integrity, authenticity, security, confidentiality,reliability and etc. but the major issue in managing the digital information issecurity.
1Security of information is the keychallenge of today from cyber attacks. There are so many algorithms and techniquesto protect cyber information from cyber attacks one of them is cryptography.The cryptography technique provides various algorithms and types to implementsecurity of information.
1This paper will focus on acomparison between symmetric and asymmetric encryption techniques to achievebetter security solutions. Keywords:Cryptography; Encryption; AES; DES; 3DES; Symmetric key encryption; Asymmetrickey encryptionI. IntroductionThehigh growth in the networking technology involves a common culture forinterchanging of the data very drastically. Hence it is more accessible of copyof data and reconstruct by hackers and viruses. Thus the information has to besecured though transmit it, Sensitive information like ATM cards, bankingdealings and public security numbers require to be secured. Differenttechniques are used to protect the confidential data from unauthorized use.Encryption is one of them and a very common technique for implementing theinformation security.
The development of encryption is moving towards aprospect of endless possibilities. Everyday innovative encryption techniquesand algorithms are being designed and developed to find better data security. Encryptiontechnique provides a verity of algorithm and types. This paper proposed thedetailed comparisons of symmetric and asymmetric encryption techniques for thebetter security results.
