“…Kerberos principal obtains tickets for authentication and respective authorization. The tickets then contains the attributes of nodes, ticket lifetime, and the session key for the requestor for accessibility over network [ 10 , 11 ]. There was a lacuna during accessibility or transmission of messages over the network for interoperability.…”

The use of internet has increased significantly in the COVID-19 pandemic, and this has set the ground for various cyber-attacks, which are executed over the network during data transmission. This scenario is proven to be multifold for accessing the cloud remotely deployed in university premises. To provide secure authentication and compatibility over heterogeneous systems for cloud accessibility, every network communication applies an encoding scheme to standardize data transmission. With many wireless and ad-hoc networks where the nature of communication is difficult to monitor, the encoding scheme prevents malicious code injection during data transmission. The objective of this paper is to study encoding schemes available for data transmission and their application in terms of authentication protocols such as Kerberos and LDAP. Furthermore, it will also emphasize on the design of integration model of Kerberos and LDAP to Cloud and Shared Storage to evaluate the impact of ASN.1 vulnerability.

“…Instead of generating a private key from a user password, the method exploits SHA-256 hashing and 3-DES algorithm. Another method [6]used Dynamic Passwords and Diffie -Hellman Algorithm to prevent dictionary attacks and to exchange passwords. The security of Kerberos Server (KDC) and replay attack is not addressed here.…”

The corporate world is intensively thinking of how to process vast datasets efficiently and securely. Apache Hadoop, an open source framework serves this requirement. Most of the current Hadoop technologies use Kerberos Authentication to incorporate security aspect to Hadoop, which suffers from numerous security and performance issues. The reliance on authentication credentials, a single point of failure as well as a single point of vulnerability, the insider threat and time synchronization problem adds to the list. A comprehensive review of various authentication issues in Kerberos-enabled Hadoop Clusters is provided in this paper. This paper proposes an authentication framework for Hadoop that uses an enhanced One-time Password (OTP) that can solve all the identified problems. The simulation results in Riverbed Modeler proves that the proposed model performs as good as traditional Kerberos Authentication Mechanism. A comparative analysis with existing mechanisms is also presented to strengthen the claims of proposed method
