Do we have AES in gate syllabus?

---

I don't think it's in syllabus but frequently asked in test series.. Better to touch the basics only.. Like aes is symmetric key encryption algorithm like DES

Answer 1

1. RSA and Diffie-Hellman both are asymmetric key algorithm
2. AES (advanced encryption standard) and DES both are symmetric key algorithm.

how DH key is the asymmetric key algorithm???

@ akash.dinkar12 

in DH two parties create a symmetric key to exchange the data without remembering key  in future. 

so here this not mean that this is symmetric key algorithm.
