It is designed for Xilinx and Altera devices. IPX-HMAC-SHA-1 is an implementation of the Key Hashed Message Authentication Code standard, which describes a mechanism for message authentication using cryptographic hash functions. It enables computation of the keyedhash message authentication code (HMAC) for audio and video assets. This HMAC module uses the SHA1 core in combination with a secret key and the text message provided by the user in order to generate a fixed length MAC value. The key advantages of the IPX-HMAC-SHA-1 IP-Core are its high throughput and low latency. Its interface can handle a frequency of at least 125 MHz, which is highly suitable for applications like Gigabit Ethernet. Resources The IPX-HMAC-SHA1 can be provided for the most recent Altera and Xilinx FPGAs. Resources can be provided on request. Key Features High operating frequency supported Low footprint Compatible with Gigabit Ethernet data throughput Ideal for Digital Cinema applications (DCI)
