Address validation using signatures

A computer-implemented method comprising:

• receiving, by a component from a device, a request i) for data stored in a memory location and ii) including data in an address field and that has a first length;
• extracting, from the data in the address field, address data that has a second length that is less than the first length;
• extracting, from the data in the address field, a first signature that has a third length that is less than the first length, the first length being a sum of the second length and the third length;
• generating, using the address data, a second signature;
• determining whether the first signature is the same as the second signature;
• and
• in response to determining that the first signature is the same as the second signature, providing, by the component and to the device, data from the memory location.

A system comprising:

• a data processing apparatus;
• and
• a non-transitory computer readable storage medium in data communication with the data processing apparatus and storing instructions executable by the data processing apparatus and upon such execution cause the data processing apparatus to perform operations comprising:
• receiving, by a component from a device, a request i) for data stored in a memory location and ii) including data in an address field and that has a first length;
• extracting, from the data in the address field, address data that has a second length that is less than the first length;
• extracting, from the data in the address field, a first signature that has a third length that is less than the first length, the first length being a sum of the second length and the third length;
• generating, using the address data, a second signature;
• determining whether the first signature is the same as the second signature;
• and
• in response to determining that the first signature is the same as the second signature, providing, by the component and to the device, data from the memory location.
