Abstract:
Advantages of Cloud Computing include its flexibility, scalability, cost savings, and
around-the-clock availability with the latest features. It’s a cloud-based remote access
paradigm that allows users to access computer resources like servers, storage, and apps.
Storage service, a key offering in cloud computing, provides secure and backed-up data
across the globe, making it ideal for client organizations. However, cloud environments
are often multi-tenant, raising concerns about data security, as both internal and
external attacks can target confidential data stored in the cloud.Cloud computing
providers do not guarantee complete data security, so client organizations prefer to
secure data at their end by encrypting it before storing it in the cloud, requiring them
to manage the encryption and decryption keys. A Key Management System (KMS) is
essential for managing these keys and their associated metadata, including generation,
distribution, storage, backup, recovery, and destruction. However, security issues
like data confidentiality and unauthorized user access may arise.In my thesis, I have
worked on a distributed Key Management System (KMS), including premise-based and
cloud-based KMS, for managing cryptographic keys. My research combines traditional
cryptographic algorithms with quantum cryptography primitive (Lattices)to secure keys
against classical as well as quantum attacks while minimizing security concerns related
to cloud-based KMS.
