Today’s digital world is entirely managed on the internet digitally. So to confirm Confidentiality, Integrity and Availability of users data in transit at rest using a hybrid encryption place particular algorithm. In this paper we are going propose approach which combination multiple symmetric block ciphers stream primarily AES-GCM, Chacha20 Poly-1305, Multi Fernet assure more security an accep...

We aim to construct a general framework for portfolio management in continuous time, encompassing both stocks and bonds. In these lecture notes we give an overview of the state of the art of optimal bond portfolios and we re-visit main results and mathematical constructions introduced in our previous publications (Ann. Appl. Probab. 15, 1260–1305 (2005) and Fin. Stoch. 9, 429–452 (2005)). A sol...
