WebJan 1, 2024 · Weaker assumption: our scheme is secure under the k-linear (k-Lin) assumption, while their scheme is secure under a stronger assumption, namely, the symmetric external Diffie-Hellman (SXDH) assumption. It is well-known that the k-Lin assumption is equivalent to the SXDH assumption when k=1 and becomes weak as k … WebAdvantages of symmetric encryption. One main advantage of symmetric encryption is its speed because keys are much shorter, and the overall process is quicker.. Disadvantages of symmetric encryption. One main disadvantage of using symmetric encryption is using the same key. This key is shared between the sender and recipient. It adds to overheads such …
