Advantages and Disadvantages of Symmetric Cryptography

Advantages and Disadvantages of Symmetric Cryptography:

Advantages:

• Keys of encryption and decryption are small.
• Using these there is a chance of generating stronger ciphers, with simple transformations.
• These are used to have a higher rate of data throughput i.e. in a range of hundreds of mega bytes/sec in hardware implementations. Where as the implementation is software generates a throughput of mega bytes/sec.

Disadvantages:

•  Being a single key at both ends, it should be kept secret at both ends.
•   As the number of keys depends on the number of communicating parties, key stack in larger networks will be more which affects the maintenance.
